What to look for in a motherboard

What to look for in a motherboard

I’ve been building PCs for more than 20 years and I tend to keep them a very long time, so it occurred to me that someone might be interested in what I look for in a motherboard to ensure both a long, reliable life and a long useful life.

Technology has changed a lot but what I look for has remained surprisingly consistent over the years.

Expanded vs Extended memory, or EMS vs XMS

Expanded vs Extended memory, or EMS vs XMS

DOS veterans may remember messing with expanded and extended memory to get memory above 640K. Here’s what you need to know about expanded vs extended memory, or EMS vs XMS. They are two different approaches to solving the same problem.

Don’t buy a “desktop replacement” laptop

I found this oldie but goodie Lifehacker article: When two computers are cheaper than one. It advocates buying a cheap laptop and building a desktop PC to meet your computing needs.

I think it makes a lot of sense. A few weeks ago, a coworker asked me what the most I would be willing to pay for a laptop. I hesitated, thought for a while, and said you might be able to convince me to spend $600. “Wow,” he said. “I’m considering a $3,500 laptop.”

I wouldn’t. Read more

Bargain potential for AMD Socket FM1s

Anandtech has an interesting overview of building HTPCs using AMD’s dead-end Socket FM1. I think it has interesting implications for anyplace you’re looking for value, not just in HTPC applications.

Yes, it’s a dead end, because Socket FM1 will be going away in favor of Socket FM2 in the coming months. But that’s one reason why there’s value potential here.

And speaking of SSDs, here’s how Oracle performs on an SSD

Andy Black is a former colleague and an Oracle DBA. Several times in the last few years, I ran into problems where I wished he wasn’t a former colleague, because my team got into some jams that I was pretty sure he could have fixed. (And let’s not even mention the time I got blackmailed into building an Oracle server.)

Last year, Andy did a thorough investigation of Oracle performance on SSDs, and observed very favorable results. Read more

Stress test computer hardware with Prime95

Let’s say you’ve just bought a used PC with a short (typically less than 2 weeks) warranty. Or a new PC that’s not the brand you know and trust. Maybe you’ve built a new PC and you want to make sure it’s going to hold up before you start using it every day. Or you have a new server, and you want to make sure it’s going to hold up under heavy loads. What should you do to stress test computer hardware (or burn in computer hardware) like that?

Do what overclockers do.

Thrift-store PCs

In the comments of a recent post I did, reader Glaurung Quena brought up a good topic: secondhand PCs, acquired cheaply, strictly as rebuild fodder.

I like the idea, of course, because I’ve been doing it for years. In the 1990s I built a lot of 486s and Pentiums into former IBM PC/ATs, basically until all the board makers relocated the memory slots into a position that wasn’t clear on the original PC/AT due to a beam that supported its drive bays. And of course the adoption of ATX and MicroATX killed that, at least for a while.

But now ATX has been around as long as the old AT architecture had been when ATX came along, and efforts to replace ATX haven’t been successful. So that trick makes more sense again. Buy a secondhand machine cheaply, intending to re-use the case, and regard anything else inside that happens to be reusable strictly as a bonus. Read more

Trailing edge computing

I found a blog entry today suggesting that you buy 3-year-old computer hardware and software.

I’ve been doing this for years, although I never put that much thought into it.The idea goes like this: Instead of buying cutting-edge computers, which depreciate faster than cars do, buy a machine that’s a few years old, and then run older software on it. He says games, but the trick works fine for other software too. Just make sure the software you run is still getting updates. Microsoft generally continues releasing updates for 10 years, for example.

He suggests scouring the bargain bins at game stores for old software, but you can get used copies of pretty much anything you want online too, such as at Amazon. If the game is rare the price can be high, but the titles you’re likely to want are also likely to be common and cheap.

I haven’t built a new PC since 2002, which might surprise some people since there was a time when I would either build a new PC or do a major upgrade once a year or so.

But it’s telling that when I built that machine I didn’t use cutting edge parts either. I used a surplus Compaq motherboard and the cheapest ATI video card I could find. Is it useful? You bet. My wife uses it every day.

The PC I use most often now is a 2 GHz Compaq, most likely an off-lease business PC. I put a discrete video card in it and filled its memory slots. It probably dates to 2002 or 2003 also, but it’s almost as peppy as the 3 GHz PC I use at work.

Needless to say, I like the idea a lot.

As far as whether you should build a PC from old (or mostly old) parts or buy an entire PC, it really depends. I bought the Compaq because there was no way I could build anything comparable for the price, even if I reused components (and I have a lot of parts I could reuse). I can assemble a PC in less than an hour, so time wasn’t a huge consideration for me, but it would be for some people. A PC built entirely with off-the-shelf components is more upgradable, but this Compaq is tiny, and I really liked that.

If I could have bought a bunch of cheap parts, I might have gone a different direction.

The first PC I ever built

I’ve noticed a disturbing trend lately: Everyone who built his own PC knows everything. Just ask him.
Now, don’t get me wrong: It’s admirable to build your own PC rather than just buying Dell’s special of the week (although some people would be better off just doing exactly that), and it does require at least skill with handling a screwdriver. But it’s not what it used to be. Today, building a PC makes you know something. It no longer makes you an expert.
