Registered modules is ECC too Practically always true, but not because of any technical requirement. They're independent variables, but there's hardly ever been any market demand for Registered memory that didn't support ECC. I believe there were some Registered non-ECC modules made for DDR1. They …

What do you think? With a few exceptions such as the theoretical CPU benchmarks in SiSoft Sandra and a few DOS tests, the K6-III 450 is better despite being clocked 50 MHz less. I haven't tested a K6-2+ myself, I just remember some other people's benchmarks (maybe philscomputerlab) that seemed to …

I am really surprised that the Asus A8N-SLI board supports registered ECC memory. Officially it's not supposed to. On my board (which is just a plain A8N-SLI, not a "Premium" like W.x. has) I recall it worked easily with 512MB Registered modules but I had to disable "Cool 'n Quiet" and maybe all …

The main reason ECC memory is cheap on eBay is because people are afraid of it. It's a great bargain sometimes, but too many sellers just say "ECC" when they should be saying "Registered", and jumbling those together keeps people away from anything that says "ECC" on the listing. ECC is nothing more …

I'm at least 10, maybe 15 years out of date on MAME, and I won't even try to talk about frontends. I don't know anything about this game, but look for a controller that's a good match to the arcade hardware you care most about replicating. Are you saying you need analog? Most arcade games use …

I found a cheap K6-III 450 AFX, i prefer the K6-III CPUs because of the larger cache. The onboard L2 Cache doesnt work anymore. I still don't understand the K6 tools. Which ones do I need and what can they do? I don't actually need overclocking, quite the opposite. Only 50 MHz more, but now there …

If you want to be a little more adventurous, with a possibility it doesn't work: The key question is whether the BIOS will support a Coppermine. Coppermine recognition/support may have made it's way into later BIOS updates but Compaq isn't likely to have ever mentioned it since it's not officially …

I agree with rasz, try Win2k/XP if you have it. I ran a Ti4200 on a P2B-F under Win2k without issue. The 980XGL is higher end but it's still the same family of cards/GPUs. I don't think Win2k even needs a chipset driver for the 440BX, you can just install the nVidia driver and it should work. Also …

The last official BIOS for the Tyan S1590 supports the K6-III, but not the "+" CPUs. The modded BIOS that adds support for the K6-2+ says something like version "J.2" on the POST screen. If that's the version you have then it should be working. I've used a K6-3+ with that BIOS, and I think a 2+ also …

Some of the boards you posted are Baby AT and some are ATX. Do you have an AT / BabyAT(BAT) case you want to use? ATX cases and power supplies are much more readily available. Older ATX cases can hold a BAT board, so this isn't a dealbreaker on using a BAT motherboard, but you still have to adapt …

You seem to have a stability problem which you're operating on the edge of, depending how you set the clocks. Make sure the dividers are set correctly (so PCI is running at or close to 33MHz). If that's set wrong, PCI could be at 1/2 of FSB which would put it in the high 40s - which won't be stable. …

Do you have a multimeter? If so, try checking the +5V and +12V voltages from one of the unused drive connectors. That's an unusual board. Not many socket 370 motherboards have AT power connectors. Those were obsolete when this board was new. They would have only been included to encourage upgrades …

The video card is an important variable. A Radeon 9800 draws heavily from the 5V rail. I think the following generation X800/etc cards draw mainly from the 12V rail.
