Dual Celerons; Chap. 9

Dead ATX power supplies. Yesterday was my first day back at work in a while (I was burning up vacation time most of last week). I “fixed” an ATX power supply first thing that morning by unplugging it and plugging it back in after waiting 10 seconds. I see that problem somewhat frequently on Micron desktop PCs for some reason. If it gets to be a regular occurrance on a particular PC, we get Micron to RMA the power supply.

Mac-PC font conversion madness. We also ran into some problems migrating some documents from Macs to PCs, so the resident Unix guru, who’s also the other resident Mac guru, and I spent all afternoon struggling with it. Finally, we just started converting a couple of the crucial Type 1 (PostScript) fonts manually to get around the problem. He had his Linux laptop with Netatalk configured, so I dumped the fonts to his Linux box, which he then converted and I grabbed on a PC via FTP.

There is no good free way to move fonts between the Mac and Windows, alas. From the Mac to Unix is no big deal. But all the freebie converters have major drawbacks. I went and got the $45 shareware CrossFont from www.asy.com and tried it out. It gave satisfactory results on two of the fonts, but totally mangled the line spacing on the third. We suspect that font has problems, so it may not be CrossFont’s fault, but it would be nice to know for sure.

Speaking of Type 1, Adobe Type Manager Light is now a free download for both Windows and the Mac. Get your copy at www.adobe.com. There aren’t a huge number of free PostScript fonts out there, but there are some.

The Epson Stylus 1520. Today was a Mac problem day mostly. I ended the day by troubleshooting an Epson Stylus Color 1520 that didn’t want to print pure colors. Pushing the clean button didn’t help. I finally just switched over to the printer’s local port (we usually print via the Epson Stylus RIP to get PostScript Level 3 support), opened an application, loaded a file, chose to print, then hit the Utility button from the print dialog box. I do wish there were an easier way to get to the utility function. I cleaned the nozzles and aligned the print heads, and voila, we once again had nice prints.

Too bad Epson hides that utility so deeply, because I spend a lot of time cleaning those stupid printers and that’s really something an end user could do, if they could remember how. (I have a hard time remembering how, which is part of the reason why I’m putting it here. Running a Web site has its advantages…)

The other problem I have with this printer is that because it cost $500, people seem to think it’s a high-volume printer, capable of printing thousands of pages a month. It’s not. It really is a consumer-grade printer. While the print quality is very good as long as you have the right paper, that’s this printer’s appeal, and that’s why it costs so much. Printing thousands of sheets a month is a great way to burn through printheads, and that’s not something that’s user-replaceable. It’s not even something I can do–it has to go into the shop. And no, when you pay $500 for a printer, you don’t get onsite service.

Dual Celerons; Chap. 9

Name-brand memory vs. generic

Dave Farquhar Hardware , , , , , , , , ,

The difference between brand-name RAM and commodity RAM. I’ve been seeing a lot of questions along the lines of, “Do I really have to buy name-brand memory when I can find memory for half the price on PriceWatch?” on message boards lately. I talked about memory some in Memory-buying secrets, but I didn’t really go into the difference between generic/commodity/broker memory and the expensive stuff.

There are three factors that go into the quality of a memory module: the quality of the chips, the quality of the printed circuit board (PCB), and manufacturing.

When memory chips are made, they are tested. A memory chip that runs at or below spec gets classified as an A-grade chip. Chips with minor defects are classified as C-grade chips and shouldn’t be used in PCs.

Memory manufacturers will also charge varying amounts based on how much testing they do for the chips. Top-tier chips are guaranteed to have a failure rate of .1% or less–we’re talking one in a thousand chips failing here.

The least expensive chips aren’t tested at all.

The only way to ensure you’re getting these best-of-the-best chips is to buy name-brand memory. The best way to ensure you’re getting C-grade or untested chips is to buy the cheapest module you can find.

Inexpensive PCBs use a four-layer design, with signal layers on the outside, and power and ground sandwiched inside. This is inexpensive to produce and easy to repair. Unfortunately, this design leaves you open to signal noise, which can corrupt the data stored in the chip, and lead to unpleasant things like BSODs.

A better approach is to put the signal layers inside, and put power and ground on the outside, protecting them. Better still is a six-layer design, which adds two more ground layers for even better isolation. The higher the memory speed, the more important this extra isolation becomes.

You can sometimes tell the difference between a 4-layer and a 6-layer board by looking at it under a strong light. By turning it slowly, you can isolate discrete layers with the naked eye. However, it’s impossible to tell the difference between power, ground, and signal layers with the naked eye.

Name-brand vendors use high-quality PCBs. Some even proudly proclaim it when they use 6-layer boards. Again, the best way to get a poorly designed 4-layer board is to buy the cheapest memory you can find.

The third factor is assembly. When soldering chips to PCBs, things can go wrong. Trust me. I’m very good at demonstrating. While no one puts together memory modules by hand (I hope), my plumber-like soldering skills make me appreciate good equipment. Quality solder joints are bright and shiny, and they’re applied very quickly. Intermittent solder joints cause problems, and they’re maddening.

Kingston puts every module through rigorous testing. Other name-brand manufacturers test as well. When you don’t even know who made your module, it’s impossible to know whether it’s had the proper testing. Putting it in a PC and watching the BIOS check is not proper testing. Memory has to be very far gone to fail that test.

Miscellaneous computer memory.
The module on the right has Samsung chips on it, but that doesn’t necessarily mean it was made by Samsung. I’d be fine with putting the HP module directly below it in a PC, though. The same goes for the Kingston module at the top of the image.

Frequently vendors will advertise Micron memory or NEC memory. A Micron or NEC stamp on the chips doesn’t necessarily mean they manufactured the module! Be sure to find out who assembled the module–they usually stamp the PCB, or they put a sticker on the module itself. If you find a so-called Micron module on Pricewatch for half the price that Crucial is asking (Crucial is a division of Micron), chances are it’s a no-name module that just happens to have Micron chips on it.

So, does it really make a difference?

As an IT professional by day, I work on a large network–roughly 700 PCs. I’ll conservatively estimate that farm of PCs has 1,000 memory modules collectively. We buy name-brand memory (Crucial, Kingston, Viking or Simple) exclusively. We buy PCs from Micron, so they have Crucial modules in them. Macintoshes generally come with Crucial or IBM modules.

A typical memory module has 8 chips on it, and it only takes one bad chip to make the whole module bad. I’ve seen two bad memory modules cross my desk–so we’re talking two bad chips out of a batch of 8,000. So if you’re buying a single module for a home PC, your chances of getting a lemon are pretty slim if you get a good name brand.

For my own use, I buy name-brand memory modules. Usually this means Crucial; I got a great deal over the summer on some PNY memory so I bought a couple of sticks. I use high-quality memory, I don’t overclock, and I generally don’t run experimental software. I almost never get a BSOD or an illegal operation error, even when running Windows 95 or 98. I reboot my Windows 9x boxes about once a month on average, and half the time that’s because I installed or uninstalled something and it requires me to reboot. To give you an idea how I use PCs, at the moment I have seven applications running, with 11 windows open between them, and two TSRs running. That’s my idea of moderate use.

I’d rather have 64 megs of Crucial memory than a gig of the cheap stuff. Hopefully now you see why.

AMD, part II. Intel will have its work cut out for it when Micron releases its Mamba chipset for the Athlon and Duron. Micron noticed a great waste of space in its Samurai chipset, so they decided to turn the wasted silicon into 8 MB of high-speed, low-latency L3 cache. Intel wouldn’t license the P6 bus to Micron, so Micron went to AMD, who of course welcomed them with open arms.

The Mamba is expected to perform 15% faster than the AMD 760. Unfortunately, I know nothing about expected release dates.

And what of AMD’s great hope for the Duron, the VIA KM133? Horrendous 2D performance holds it back. While it has the memory bandwidth of the earlier KT133 and KX133 and offers decent 3D performance, its 2D performance seriously lags behind the SiS 730–and SiS video isn’t exactly renowned for performance. In other words, the reason the Savage series flopped as a standalone card remains. Intel’s integrated chipsets put up better numbers overall, so if AMD’s going to beat Intel in this space, it’s going to have to be on price.

The new Musicmatch Jukebox. I normally don’t pay any attention to this app, but I caught a review of it and it includes a compelling new feature. It’s optional, and most privacy activists will hate it, but that’s why you can turn it off. For me, it’s the draw.

Tell it your favorite artist, and it streams stuff that other people who like the same thing like. I punch in Aimee Mann (who else?) and it responds by playing a set of Aimee Mann, Moby, Abra Moore, and Lou Reed. Nice. The next set was David Bowie, Iggy Pop, and Blur. And none of the tracks was the artist’s best-known song.

For me, the whole point of radio is to discover new stuff. I love my music (I’ve got a modest-sized collection of nearly 200 CDs), but radio has become so repetitive and it’s really hard for a quality artist like Aimee Mann to get any radio play. And when she does get play, it’s “Voices Carry” (her smash 1985 hit with her band, ‘Til Tuesday), or if a station is especially progressive, her Oscar-nominated “Save Me.” About once a year, you might hear one of her minor hits like “I Should Have Known” or “That’s Just What You Are” or “Red Vines.” The problem is, she doesn’t have the promotional engine behind her to give radio stations much of anything in return for playing her stuff (short of the occasional concert ticket, but she doesn’t tour much). So we get the same ‘N Sync and The Backstreet Boys and Celine Dion and Elton John songs over and over and over. Nothing new about that.

Sometimes a good station does come around, but when you hear a new song, good luck finding out anything about it because the DJ usually doesn’t say (except for the songs everyone already knows). When a song is playing, MusicMatch optionally brings up a browser window with album info, a review, a listing of the most popular tracks off the album. And in some cases, you can download a free track off the album. And–unlike radio–if you don’t like a track, you can skip it!

You can also choose from a list of 18 preset stations, and you can tell it to mix selections from the stations. So if you yearn for the days when AOR stations mixed in a dash of alternative music, you can approximate it by mixing Classic Rock, Hard Rock, and Adult Alternative (since that’s what they now call most of the stuff that was considered alternative in 1992).

The other nice thing is it’ll favor the artists whose MP3s you rip using the program in the 18 preset stations. So presumably if I rip a lot of Badfinger and Cars (I still have trouble calling The Cars classic rock) tunes, if I click on the Classic Rock station I’ll hear something other than a constant barrage of Led Zeppelin, Pink Floyd and Rush (which, as far as I can tell, is all that anyone listened to in the ’70s). Sounds good to me.

This, I think, is a killer application for the Internet. Musicmatch is at www.musicmatch.com.

Spam. If it sounds too good to be true, it is. At least the phrase “boost the reliability of ordinary Windows 3.x…to nearly the level of Windows NT or 2000” gave me a chuckle.

Ignore these chumps.

Dear Windows User,

Now you can boost the reliability of ordinary Windows 3.x, 95 and 98 to nearly the level of Windows NT or 2000, Microsoft’s professional and industrial version of Windows.

The new WinFix 4.3 is a very effective way to improve the reliability of Windows, because it makes Windows fault-tolerant and self-repairing. And WinFix is very safe, because it operates completely independent of Windows.

This can’t wait. The two graphics giants have wed, sort of. nVidia has purchased 3dfx’s core assets.  That’s the end of the line for 3dfx.

This leaves nVidia as the undisputed leader in 3D graphics, and in graphics, we’re now down to a Big Three of nVidia, ATi and Matrox, with ATi and Matrox making boards and nVidia supplying other board manufacturers such as Guillemot and Creative.

So, what went wrong? A lot of things. They were late delivering new products. They lost focus, buying out struggling boardmaker STB and entering the graphics card business. In doing so, they entered foreign territory and they alienated their former allies. Rather than strengthening their brand, it weakened it–suddenly there was one company promoting their stuff, rather than six or seven. Then the combined company had to sell their product for such a low price, it killed profitability and harmed them more than it harmed the competition. Dumping only works when you’re much bigger than your competitiors.

They made a good product, and really, they deserve a lot of credit for reinvigorating the PC game market. But history is littered with the carcasses of companies that made great contributions but weren’t able to remain competitive for one reason or another.

Apologies for the supershort post. I’ve got a story to tell, and that’s the main reason why my mind isn’t working so well right about now. It’ll be here in the morning.

Corel pulling out of the Linux market? It’s no great surprise, but there are reports that Corel’s selling its Linux business.

The original P4 design. If you thought the Pentium 4 seemed underly ambitious, there’s a reason for it. Read about what it almost was at The Register.

Makes me wonder if once they get down to .13 micron, if they might not dust off more elements of the original design and give it a shot. AMD may force their hand, if their 32/64-bit Sledgehammer CPU is as good as they’re saying it will be. (Question is, is that the engineering department or the marketing department talking?)

By the way, there are Linux distributions incompatible with the P4. They don’t recognize the CPU so they refuse to run. The various companies are releasing patches to fix the problem.

The Asus A7V motherboard and Unix. I’ve been seeing a lot of search engine hits with phrases containing “Asus A7V” and various Unix bretheren (NetBSD and Linux, most recently). I know exactly what posting is turning up under that query–the dream system of a few weeks back.

Is there something weird about the A7V and the BSDs and Linux that people should know about? Installation difficulties? Or are people just trying to confirm compatibility?

Any of you intrepid searchers care to comment? I have to admit, you’ve got me curious.

I used to keep a trap for spambots on the page, but this is more effective. Though maybe I should set a trap again. Depends on how vindictive I feel, I guess.

Disable your screen saver before playing DOS games inside Windows. I forgot to mention this little tidbit in Optimizing Windows, and I also forgot to mention it in my upcoming Computer Shopper UK article, which is about getting cantankerous DOS games running, even under the reputedly DOS-unfriendly Windows Me.

The games will run, but if you’re sitting there thinking for a long time and your screen saver kicks in at the wrong moment, your system may freeze. Doesn’t seem to happen all that often, but it happened to me yesterday when I was playing The Secret of Monkey Island (I’d forgotten how much I love that game).

That game also makes me feel old. I first played it on a CGA system. Needless to say, it looks a lot better in VGA.

My standard screen saver advice. Screen savers are generally a bad idea anyway, because most screen savers do more harm than good these days. In the days of low refresh rates, images could burn into the screen’s phosphers if the screen sat idle for too long. The high-refresh monitors made since 1994 or so are largely immune to this. But people continue to use screen savers out of the mistaken belief that they’re good for your computer, or because of tradition, or because they look cool.

The more colors a monitor has to display in rapid succession, the more likely it is to deterriorate quickly. The easiest color for your monitor to display is black, because all the guns are off. Keep a rapidly changing image up on the screen, and your monitor actually ends up working harder. As does your CPU–the 3D screen savers make your CPU work harder than Word and Excel and Outlook do. Combined. This increases heat and electrical usage, two things that businesses tend to worry about a lot. They buy green PCs, then keep their energy-saving features from ever truly kicking in (other than spinning down the disk, the savings of which is negligible) by not banning screen savers. Yet they think they’re being all eco-friendly.

Case point: one of the PCs I use at work was first used by a contractor we let go back in March after he’d been there about a year. He had every gimmicky blinky obnoxious screen saver out there, and he used them, leaving the monitor on all the time. The monitor still works, but the color is all messed up. The color quality on my ancient NEC MultiSync 3FGe at home is much, much, much better than on this two-year-old Micron-branded monitor.

If you want to treat your monitor right, use the Blank Screen screen saver or another blanker. And don’t fret if you have to disable it from time to time.

Impressions of Windows Me

Dave Farquhar Windows , , , , , , , , , , , ,

Afternoon: Short shrift thoughts on WinMe. I’ve got it running on a Celeron-400. I installed a 15GB Quantum Fireball lct I bought some time back and never used for anything, so as to preserve my existing Win98 setup. I see little difference between WinME and 98SE, with a few exceptions:

Improved Defrag. Defrag’s speed now rivals that of a third-party package. It still won’t give the results that a well-tuned Norton SpeedDisk will, but at least the days of 18-hour defrags are over.

Improved boot times. When I saw people bragging that WinME made their systems boot in a minute and a half, I was hardly impressed. I can get even Win95 to boot many systems in under 30 seconds. WinME booted this C400 in 15 seconds. I did the boot speed tricks out of Optimizing Windows, and got the boot time down to 14 seconds. So Microsoft has obviously streamlined the boot process considerably. The old tricks still work, but don’t give much improvement. But what would you rather do, pay $50 or $90 for a faster boot time, or spend 5 minutes streamlining your MSDOS.SYS file?

Stability. WinME is a bit more solid on this C400 than vanilla Win98 was. I’m currently serenading my neighbors with an MP3 tune from A Flock of Seagulls (I’m sure they appreciate it) while I’m on the Web. That was a great way to make the system bluescreen before. Of course, that could just be due to a fresh installation as well. That 98 installation is about 14 months old, so it’s due for a scrubdown.

Speaking of sound… I bought the SB Live! card in this machine mostly for its voice recognition abilities, but the sound quality coming out of this thing is far greater than any other sound card I’ve seen. If you’re in the market for a sound card, give Creative’s SoundBlaster Live! series a long, hard look. Now that their main competition is buried I don’t know how long they’ll keep making good stuff, but this card is something else.

Morning: I finally did it. I did what I recommend no one do. I bought a copy of Windows ME last night. I’m making a bit of a living writing about 9x, so I had no choice. I’m writing a Windows optimization series for Computer Shopper UK, and I have to cover ME because that’s what an increasing number of people have.

I could review it here but I doubt I’ll bother. I can’t imagine anyone would be interested. The best advice for any Microsoft 9x product is to not buy it unless you buy a new PC that comes with it. That was true for four years, and with ME’s lack of backward compatibility with DOS, it’s probably even more true.

My new project is starting to rival the ramdisk project in difficulty. Windows ME appears to be faster and more stable than its predecessors but I don’t like the installation program. It seems to take liberties I wish it wouldn’t with the existing Windows directories it finds. Why do I care about that? You’ll find out if I’m successful — I don’t want to get anyone’s hopes up yet. Plus a little air of mystery is always a good thing.

Subject: Memory Brands
Dave,

First let me say that I’m probably not the first person to question your choice in memory, and I probably won’t be the last.

Have you ever heard of a company called Mushkin, Inc.? They were just purchased by Enhanced Memory Systems (the fine makers of the first PC-150 SDRAM chip and HSDRAM modules). I have used Mushkin’s memory modules for a little over one year now, and I must say that I have been very pleased. Out of several hundred of these parts that I have sold to my clients, only one such module has ever failed. The best part: it worked fine until their building was directly struck by lightning.

Read Anand Tech’s “PC133 SDRAM Roundup – April 2000” here http://www.anandtech.com/showdoc.html?i=1213 . You’ll be amazed at the performance of the Mushkin modules. Unfortunately, this performance comes at a cost. Their 128 MB High-performance revision 2.0 modules cost $166.00 each. (I get a small discount since I’m a reseller, and I order in large quantities. This price is retail.)

These modules are also very stable. I’m using mine with my timings set for “Turbo”, my CAS Latency set for “2”, and my memory clock at “133 MHz” in the CMOS setup. Using both Windows 2000 Professional SP1 and SuSE Linux 6.4, I have not yet had a lockup or error. The system has been running stable for almost three months.

I have used Micron memory in the past, and I will probably use them again. If a customer either does not want to pay the price for the Mushkin parts, or they simply don’t believe me when I tell them that those few extra dollars almost guarantees a more stable and higher performing part, then I will gladly sell them the Crucial/Micron memory. I don’t want to keep pushing something that I know my customers won’t buy.

My point is this: since you’re recommending parts based on “money is no object” then you should go with the best parts available. I believe Mushkin fulfills that role.

Sincerely,

Well, all this time of posting that picture of your book “Optimizing Windows” paid off. I saw it in the store today and bought a copy.

I don’t know if it’s such a good idea to post a picture of yourself, though: I have vinyl records older than you.
(What are vinyl records?)

~~~~~

Thanks! I hope you enjoy it and find it useful.
 
Hmm, vinyl records. LPs spun at 33 1/3 rpm; singles came on smaller discs that spun at 45 rpm. Older records spun at 78 rpm. You had to put little plastic inserts in the holes in 45s so you could play them on most turntables. I read about them in history class.
 
Actually, I bought records in the early 1980s. I think CDs became commercially available in 1983 but they sure weren’t commonplace until later–I know the first recording to sell a million copies on CD was U2’s The Joshua Tree, in 1987. I didn’t get a CD player until 1989, so until then I was buying records and tapes. I know around here somewhere I have vinyl records older than me too.
 
Not sure if my age is a disadvantage or not. I frequently tell people that computers are the only thing large numbers of people want a 25-year-old’s opinion on. I spend enough time talking about Amigas that people probably figure out pretty fast that I didn’t become interested in computers in the 1990s. I was always fascinated with them (I first saw one in 1981) and from second grade on, we had them in school. I was writing simple programs when I was 10, and by the time I was 15 I had enough confidence to take them apart and work on them. There are plenty of writers with as much or more computer experience, but there won’t be very many who’ve spent as great a percentage of their lives with them.
 
I know when I was selling the things, the younger you looked, the more credibility you had. Then again, people equate age with wisdom, and I grew a beard mostly because it gives me a few years and I notice the difference at work. I’ll probably change the photo at some point, but for now I’ll see how this one flies.

Cool. So far I don’t see anything in WinMe that I object to, and maybe, just maybe, there’s enough in it for the $50 “limited time” step-up from 98/98SE to be worth it (especially if you can get it at a slightly discounted price). If your system is old enough to be running Win95, however, I see no use for it. There aren’t enough new features to be worth the $90 going rate and the system is likely to be marginal enough that WinMe will be a slug on it.
 
The Zip folders feature is nice, making working with Zip files in Explorer just like working with any old folder. That saves you whatever WinZip costs and I think I like it better. Internet Connection Sharing, of course, is a must for some people. Those two make it worth upgrading from vanilla Win98. I can’t comment yet on stability or compatibility.

How to get noticed: Get sued

Dave Farquhar General , , , , , , , ,

~Mail follows today’s post~

Linux Today antics continue. I see on Jerry Pournelle’s site that they’ve dared him to sue them for libel. Smart move on their part, actually–I remember in my Magazine Publishing class, we raised the question in one session of how to drum up publicity for an upstart that nobody knows or cares about. (Linux Today would certainly qualify as this–it’s small potatoes and obviously knows it.) I raised my hand. My project in the class was a rebel computer mag. I’m sitting there in ripped-up jeans and a Joy Division t-shirt, known among my peers as the managing editor of a student newspaper that had an audience mostly because we baited the big, established paper, and my business plan called for taking this to the next level.

“Get sued,” I said.

Several people laughed. The professor gave me a look he gave often, a look that said, basically, I don’t know yet where you’re going with this, but I’ll humor you.

“It’s cheaper than advertising and it lasts longer,” I continued. “Suddenly, you’re news. People pay attention to you because someone big and important pays attention to you. By the time it manages to get through the courts, you’re either huge or you’re out of business, so it doesn’t matter.”

It made for nice classroom theory. It might work in the real world. But such kamikazee tactics are a sheer sign of desperation that begs the question: Why are they desperate? What do they know that the rest of us haven’t figured out yet?

Chances are, rather than sue, Jerry Pournelle will just solve the problem by eventually not saying a word about Linux at all. Linux zealots never say anything about John C. Dvorak, because Dvorak never says anything at all about Linux. The other lesson Linux Today and the zealots need to learn is that there’s no such thing as bad publicity. Whatever Jerry Pournelle or any other mainstream columnist says contributes to mindshare. Mindshare, not rose-colored glasses, is what wins marketplace battles. It’s not like anyone who knew anything had anything nice to say about the original IBM PC–it won because of sheer mindshare.

This is a tired subject, and I’m dead tired. Time for lunch and a nap.

Hello again Dave, glad to see you posting again. If you don’t remember me I e-mailed you about the compaq I was working on that had memory on the

“Hey, who was the genius who decided it was a good idea to cut, copy and paste files from the desktop?”

Have you tried http://www.officerecovery.com?
I noticed you said you downloaded a recovery program, but you did not say which one, so if this wasn’t it I hope it can still help you.  I found it
a few months back when a paniced friend called me and said he had a report due the next day and that his office document was corrupted.  Luckily, the demo version that I downloaded was able to get the cruicial

On to my question, this is a good one too.  I put together a computer for my roomate and I tried upgrading it. (I’m using this computer now since
mine sucks[acer] and i’m waiting on DDR memory so I can start a new system)

Got the picture? I mainly use it to play Asherons Call, to schoolwork, e-mail, ect.

So, for the upgrade, i’ve got a 13.6Gig Hd and I’m going to buy a 128meg Dimm since they are SO cheap now.  Here is where I ran into a problem.  I usually check pricewatch and some other sites to keep track of what things cost.  If I want to upgrade the processor on this computer my only option that is worth it is a Higher Mhz k6-3.  The problem is they are expensive.  2 weeks ago I noticed that they were under 60$, so I ordered one, a 450Mhz k6-3.  I ploped it in to my board and the bios comes up, says it’s running at 50Mhz and checks the memory then
stops.  Now, I expected this, because the processor I bought was a MOBILE processor, AND, I made sure my board supported the voltage (2v) and made sure to set it at 2v. But it didn’t boot.  I tried everything, set all the bios settings to default, rebooted, even tried lower than 450Mhz clock speeds. but no, it wouldn’t
work. Unfortunatley they won’t take it back because they EXPECT people to not set their boards to 2v and fry them (and I don’t blame them).  What I’d like
to know is if you know any way to get this to work?

Things I may try are:
taking everything out except the video card, trying dimms instead of simms, tweaking bios so everything is at minimum settings pulling my hair out (which will be hard cause I have thick hair) I know it was foolish, but, If I could get this to work I can put my old system backtogether and give it to my uncle and cousins, who really could use a omputer for school.  Well, thanks for everything, just so you know I’ve always highly recommended your books to everyone I know that is into computers (some have even bought it too) and I look forward to your next work.

I remember your name; I don’t remember the Compaq problem specifically (I rarely do). Good to hear from you again.

I’d heard of OfficeRecovery.com but I don’t know that I’ve ever tried their stuff out. I certainly will. It’s 11 pm and I just called and left a message on her voice mail that someone who read Optimizing Windows and reads my site had a suggestion for something I could try. Weirdest hour in the world, but I wanted to make sure she didn’t delete the corrupt files if she hadn’t
already. (Authorship has its priveliges–we have smart readers who always know something we don’t, and sometimes are willing to share. Thanks!)

Your question may not be too tough, especially since you do have a working CPU. Indicating a 50 MHz CPU speed usually means the BIOS doesn’t recognize
the CPU properly. Go to FIC’s page and download the very newest BIOS. I’ve noticed most of the reputable Super 7 manufacturers have revved their BIOS lately to support AMD’s newer stuff. So get the newest BIOS, flash the board, load setup defaults (if you have a choice between safe and turbo or safe and normal, go safe–I know the 503+ but it’s been a while since I worked with it), then try bringing up a minimal system (new CPU jumpered properly, just a video card, and a pair of SIMMs) and see what appens. Once you get it working, tweak the BIOS settings for better speed and add hardware, using the good engineer’s method of one change at a time.

I checked FIC’s site for VA-503+ BIOSes, and none of them explicitly list 2v MD CPU support, but it’s possible, especially if you have a particularly old revision, that something about the newest BIOS will allow it to work. They did make a lot of changes related to the K6-III in the past.  And you bring up an excellent point: The two things that usually stand in
the way of CPU upgrades are voltage settings and BIOS support. Sometimes, unfortunately, you have one but not the other. Hopefully this time you can
get both; the 503+ is a pretty good board, and a r
arity these days in that it’s AT, takes both SIMMs and DIMMs, and works with reasonably fast CPUs.

If you get it working, be sure to pair it up with good memory. I’ve always recommended Crucial; another reader wrote in this week recommending Mushkin
(www.mushkin.com), which is more expensive but he says his systems run even more stable with it than with Micron/Crucial stuff. Please don’t buy one of
the commodity DIMMs currently running $53 on  PriceWatch; sometimes those work, frequently they appear to work but then give you trouble down the
line.

Thanks for the compliments on the book, I really do appreciate it! I don’t know when I’ll write another right now; I really enjoyed this last magazine
piece and would like to just keep going that route for a while. I’m signed up to do two more and hopefully that’ll lead to still more stuff down the line. These are UK-only, but there’s a possibility I’ll be able to get them published in the States at some point as well. I may have another Web exclusive coming up soon, provided I didn’t burn too many bridges this week.
It’s unpredictable but it makes it more exciting.

Apple. you call this tech support?

Dave Farquhar Macintosh , , , , , , , , , , , , , ,

This is why I don’t like Apple. Yesterday I worked on a new dual-processor G4. It was intermittent. Didn’t want to drive the monitor half the time. After re-seating the video card and monitor cable a number of times and installing the hardware the computer needed, it started giving an error message at boot:

The built-in memory test has detected a problem with cache memory. Please contact a service technician for assistance.

So I called Apple. You get 90 days’ free support, period. (You also only get a one-year warranty unless you buy the AppleCare extended warranty, which I’m loathe to do. But I we’d probably better do it for this machine since it all but screams “lemon” every time we boot it.) So, hey, we can’t get anywhere with this, so let’s start burning up the support period.

The hold time was about 15 seconds. I mention this because that’s the only part of the call that impressed me and my mother taught me to say whatever nice things I could. I read the message to the tech, who then put me on hold, then came back in about a minute.

“That message is caused by a defective memory module. Replace the third-party memory module to solve the problem,” she said.

“But the computer is saying the problem is with cache, not with the memory,” I told her. (The cache for the G4 resides on a small board along with the CPU core, sort of like the first Pentium IIs, only it plugs into a socket.) She repeated the message to me. I was very impressed that she didn’t ask whether we’d added any memory to the system (of course we had–Apple factory memory would never go bad, I’m sure).

I seem to remember at least one of my English teachers telling me to write exactly what I mean. Obviously the Mac OS 9 programmers didn’t have any of my English teachers.

I took the memory out and cleaned it with a dollar bill, then put it back in. The system was fine for the rest of the afternoon after this, but I have my doubts about this system. If the problem returns, I’ll replace the memory. When that turns out not to be the problem, I don’t know what I’ll do.

We’ve been having some problems lately with Micron tech support as well, but there’s a big difference there. With Apple, if you don’t prove they caused the problem, well, it’s your problem, and they won’t lift a finger to help you resolve it. Compare this to Micron. My boss complained to Micron about the length of time it was taking to resolve a problem with one particular system. You know what the Micron tech said? “If this replacement CPU doesn’t work, I’ll replace the system.” We’re talking a two-year-old system here.

Now I know why Micron has more business customers than Apple does. When you pay a higher price for a computer (whether that’s buying a Micron Client Pro instead of a less-expensive, consumer-oriented Micron Millenia, or an Apple G4 instead of virtually any PC), you expect quick resolution to your computer problems because, well, your business doesn’t slow down just because your computer doesn’t work right. Micron seems to get this. Apple doesn’t.

And that probably has something to do with why our business now has 25 Micron PCs for every Mac. There was a time when that situation was reversed.

The joke was obvious, but… I still laughed really hard when I read today’s User Friendly. I guess I’m showing my age here by virtue of getting this.

Then again, three or four years back, a friend walked up to me on campus. “Hey, I finally got a 64!” I gave him a funny look. “Commodore 64s aren’t hard to find,” I told him. Then he laughed. “No, a Nintendo 64.”

It’s funny how nicknames recycle themselves.

For old times’ sake. I see that Amiga, Inc. must be trying to blow out the remaining inventory of Amiga 1200s, because they’re selling this machine at unprecedented low prices. I checked out www.softhut.com just out of curiosity, and I can get a bare A1200 for $170. A model with a 260MB hard drive is $200.  On an Amiga, a drive of that size is cavernous, though I’d probably eventually rip out the 260-megger and put in a more modern drive.

The A1200 was seriously underpowered when it came out, but at that price it’s awfully tempting. It’s less than used A1200s typically fetch on eBay, when they show up. I can add an accelerator card later after the PowerPC migration plan firms up a bit more. And Amigas tend to hold their value really well. And I always wanted one.

I’m so out of the loop on the Amiga it’s not even funny, but I found it funny that as I started reading so much started coming back. The main commands are stored in a directory called c, and it gets referred to as c: (many crucial Amiga directories are referenced this way, e.g. prefs: and devs: ). Hard drives used to be DH0:, DF1:, etc., though I understand they changed that later to HD0:, HD1:, etc.

So what was the Amiga like? I get that question a lot. Commodore released one model that did run System V Unix (the Amiga 3000UX), but for the most part it ran its own OS, known originally as AmigaDOS and later shortened to AmigaOS. Since the OS being developed internally at Amiga, Inc., and later at Commodore after they bought Amiga, wasn’t going to be ready on time for a late 1984/early 1985 release, Commodore contracted with British software developer Metacomco to develop an operating system. Metacomco delivered a Tripos-derived OS, written in MC68000 assembly language and BCPL, that offered fully pre-emptive multitasking, multithreading, and dynamic memory allocation (two things even Mac OS 9 doesn’t do yet–OS 9 does have multithreading but its multitasking is cooperative and its memory allocation static).

Commodore spent the better part of the next decade refining and improving the OS, gradually replacing most of the old BCPL code with C code, stomping bugs, adding features and improving its looks. The GUI never quite reached the level of sophistication that Mac OS had, though it certainly was usable and had a much lower memory footprint. The command line resembled Unix in some ways (using the / for subdirectories rather than ) and DOS in others (you used devicename:filename to address files). Some command names resembled DOS, others resembled Unix, and others neither (presumably they were Tripos-inspired, but I know next to nothing about Tripos).

Two modern features that AmigaOS never got were virtual memory and a disk cache. As rare as hard drives were for much of the Amiga’s existance this wasn’t missed too terribly, though Commodore announced in 1989 that AmigaDOS 1.4 (never released) would contain these features. AmigaDOS 1.4 gained improved looks, became AmigaOS 2.0, and was released without the cache or virtual memory (though both were available as third-party add-ons).

As for the hardware, the Amiga used the same MC68000 series of CPUs that the pre-PowerPC Macintoshes used. The Amiga also had a custom chipset that provided graphics and sound coprocessing, years before this became a standard feature on PCs. This was an advantage for years, but became a liability in the early 1990s. While Apple and the cloners were buying off-the-shelf chipsets, Commodore continued having to develop their own for the sake of backward compatibility. They revved the chipset once in 1991, but it was too little, too late. While the first iteration stayed state of the art for about five years, it only took a year or two for the second iteration to fall behind the times, and Motorola was having trouble keeping up with Intel in the MHz wars (funny how history repeats itself), so the Amigas of 1992 and 1993 looked underpowered. Bled to death by clueless marketing and clueless management (it’s arguable who was worse), Commodore bled engineers for years and fell further and further behind before finally running out of cash in 1993.

Though the Amiga is a noncontender today, its influence remains. It was the first commercially successful personal computer to feature color displays of more than 16 colors (it could display up to 4,096 at a time), stereo sound, and pre-emptive multitasking–all features most of us take for granted today. And even though it was widely dismissed as a gaming machine in its heyday, the best-selling titles for the computer that ultimately won the battle are, you guessed it, games.

10/30/2000

Dave Farquhar General , , , , , , , , ,

Leading off, some baseball news. Baseball and network execs are puzzled over why this was the lowest-rated World Series ever. (Story here.) Could it be that no one’s interested in watching $200 million worth of spoiled brats from New York throw temper tantrums? Nah, couldn’t be.

Baseball needs a Cinderella story. Bad.

Athlons are dirt cheap. Don’t buy one. Dan Seto noticed and mentioned that AMD Athlons are now cheap as dirt, at least compared to their once-stratospheric levels. He cited a 1 GHz Athlon for $320. So I hopped on the Web, and sure enough, you can easily find one in the $300 range. Some of the bottom-feeder vendors are selling them for as little as $260.

The rest of the lineup? 700/$99, 750/$108, 800/$129, 850/$146, 900/$166, 950/$224.

Remember, though, before you rush out to buy a supercheap gigahertz CPU, that CPU speed is but one factor in performance. Match it up with a video card that treats you right, and with a sound card that isn’t going to suck up all your CPU cycles (the SB Live! MP3+ is an outstanding inexpensive choice), and most importantly, with a hard drive that doesn’t hold you back. If you’re building a performance system, particularly one that’ll be running Linux, NT, or W2K, give serious thought to a SCSI disk. You’ll be happier with a SCSI-equipped 700 MHz system than with an IDE-equipped GHz system.

If money were no object, here’s what I’d get today and why (then I’ll tell you why I still wouldn’t buy it, even if money were no object):

  • Asus A7V mobo — most stable Athlon board available, and every time I buy something other than an Asus I regret it later
  • AMD Thunderbird 1.2 GHz — strictly for braggin’ rights
  • 256 MB Crucial PC133 RAM — Micron memory, the best in the business
  • Adaptec 29160 Ultra160 SCSI PCI host adapter — hey, it’s Adaptec
  • Seagate Cheetah X15 18GB 15K RPM hard drive — Who cares about drive size? This bad boy has a 3.9 ms seek time, a 4-meg buffer and 15,000 rpm spindle speed. It’ll heat my apartment, it’ll wake up my neighbors, but I won’t wait on it (much).
  • Plextor UltraPlex Wide 40X CD-ROM — I love my Plextor drives
  • Plextor 12X CD-R with Burnproof — no coasters with this drive
  • Sound Blaster Live! Platinum — same as the MP3+ but with a nice front-mounted breakout box for my audio gear
  • 3Com 3CR990 NIC — this is the coolest NIC on the market, far and away. It has an onboard processor that handles much of the TCP/IP encapsulation itself, freeing CPU cycles. Same principle as 3D acceleration on your video card and DirectSound acceleration on your sound card. A hundred bucks, but probably worth every cent. Nobody seems to know about it, so I’m telling you.

I wouldn’t worry so much about the video card. My two-year-old STB Velocity 128 frankly is enough card for most of what I do. I suppose I’d get an nVidia GeForce256-based model of some sort. Since the nVidia Riva128 chipset has long since been sent to the gulag, the value chipset is the TNT2. Hot tip if you’re building a value PC: I’m seeing Creative Labs OEM TNT2-based cards for $60, and that’s more than enough card for all but the most die-hard gamer.

Amazingly, you could have this system for well under $3,000. I figured buying the best of everything would run into the $4500 range easily.

I suspect AMD slashed prices precisely because this is a good time to wait and they don’t want you to. Those in the know know that the AMD 760 chipset, which supports DDR SDRAM (basically 266 MHz SDRAM) comes out this week, so anything available today is old hat. This isn’t the multiprocessor AMD 760MP though — we’re looking at January for that. Sorry.

So why not buy now and replace the motherboard later? The 760 introduces a newer, faster front-side bus. If you want to exploit its full potential, you need a new CPU. No one is going to want these old ones now.

I spent a good part of the weekend working on an article. Essentially, I’m distilling chapter 2 of Optimizing Windows into a 3,000-word piece. That’s hard. The tips fit into that, but with very little explanation and very little flair. So much for the difference between it and every other “21 Ways to Speed Up Windows” article, except mine may be more complete for lack of explanation and flair.

Some argue they don’t want flair. They’re lying. Without flair, it reads like an economics textbook. Without explanation, you haven’t done anyone much good.

The line I really don’t want to lose: “I hate screen savers. I hate them so much, when I was once invited to make an appearance on a US television program called The Screen Savers, I turned them down.” Then I go into explaining why screen savers are the cause of everything wrong with the world today.

I was at 3,600 words Saturday, down to about 3,200 by Sunday afternoon. I can cut the two least important tips, leaving 20, and be at 2946, which might leave room for some screenshots. I’m half tempted to ask him if I can do the page layout for this thing as well… That’s not likely, but worth asking.

Fun with electricity

Dave Farquhar Hardware , , ,

Fun with electricity. I’m trying to figure out if I’m overreacting or not. What really scares me is that this journalist seems to know a whole lot more about electrical safety than some other people working in an IS/IT department.
The scenario: I had a PC that wouldn’t boot or power off. It sat there in a catatonic state, HD LED solid, power LED solid, fans running, but no other signs of life. The only way to power it off was to pull the plug. Plug it back in, and it reverted instantly to the catatonic state. I popped the hood and didn’t see anything obvious. I did notice a weird smell, which isn’t unusual for an electrical problem, but it was somehow different. Organic… I unplugged the ATX power connector and went and plundered an ATX power supply from an old P166. I came back, plugged the plunder into the board’s power connector, connected the cord, and hit the switch. It fired up and the system POSTed. OK, it’s a short in the power supply. I’ll just e-mail Micron with the details and the serial number, and they’ll overnight me another one. In the meantime, this one’s not doing anything anyway.

So I unbolt the bad one, pull it out, flip it over, and get a nice splash of black liquid. What the? 10W40!? In a computer!? Wait… Suddenly the smell made sense. Old coffee. With cream and sugar, judging from how sticky my hands were getting. So I went to the facilities to wash my hands and get some paper towels to clean up the coffee spill that had now migrated to the IDE cables and elsewhere inside the case.

I cleaned up, assembled the system, and e-mailed my boss and my boss’ boss to ask what, if anything, needed to be said or done. My boss is incredibly busy, but my boss’ boss asked if we could loan them another Pentium II until theirs was fixed. I told him he was missing the point: I already got their computer working. My problem with the situation was we had an electrical device with liquid in it and no one told me before I started trying to fix it. The $35 power supply is meaningless. It’s a lot more expensive to repair or replace techs if they electrocute themselves.

He asked me what part of policy isn’t working if it’s not safe to work on equipment.

Am I the only one who remembers from grade school not to put a hair dryer in the bathtub? It’s the same principle, just with more current and less liquid. And I also remember from science class that pure water isn’t a conductor. It’s the stuff dissolved in the water that conducts. St. Louis has hard water. Add coffee. Add cream and sugar. Now you’ve got enough conductivity to short out the power supply. Having some idea what kind of juice accumulates in the power supply (I shook hands with a power supply a few years ago, which is why I don’t open power supplies anymore), this situation strikes me as dangerous.

I was at least owed the courtesy of being told they spilled coffee in there so I knew not to reach in with both hands and complete the circuit. The embarrasment is better than finding a dead Dave laying in their cube next to a dead Micron, isn’t it?

I guess I didn’t explain it well enough.
