Re: A 40 MHz FSB → and PCI ← 486 Motherboard

How do you know your integrated IDE is running at 40 MHz and not at 27 MHz? For example Luckystar LS486E has specific jumper for 1:1 PCI bus.

Late C3 (Nenemiah) are not the best option for underclocking and I would say that it's so hard to find. Ezra/Ezra-T are better and there's plenty of those on ebay.

I did extensive tests only with FPM. so that's not the case.

Most motherboards will run with a 40 MHz PCI bus just fine, minus the onboard IDE So far I had no trouble with integrated IDE on my SIS boards.

Actually it works with EDO. Probably will put it on the back burner. Because I don't have required parts and not so sure if this will help.

I was wondering about this particular motherboard - if anyone has been able to get L1 write-back working on it. Can't test mine due to dead voltage regulator and DX4 overdrive in my possession is WT only.

That's how both SLI and Crossfire work since introduction I think SLI scissor mode reduced VRAM usage for frame buffer on each card. Maybe ATI tiling mode did that as well.

Motherboard was received "as is". It works fine without L2 cache. BIOS time stamp and description: 06/25/96-SIS-496-497B-PVI-4SP3C-00 All SRAM works fine in another board. Yes.' P.S. Replaced all jumpers - no luck.

Board is in good shape, no parts are missing or damaged. I've checked the chipset pins with a needle and they look okay too, everything is solid and without short circuits. Tried to change some jumpers with no luck, will try to change all later. But it seems that buffer theory is the most plausible …

So, apparently 320x200 (640x400) mode is plagued by vertical lines just as early Trident video cards, when paired with LCD monitor. But this model has a lot of jumpers (mine even has DIP switches on the back), is it fixable?

I think it would much easier to find more modern card.
Re: Pentium 3 Xeon slot 1 mod?
Posted on 2018-07-21, 06:16
Nearly impossible to mod due to difference in size, notches, slot pins, etc. Probably possible to design custom adapter, but that would require BIOS rewrite too. So good luck with that. Also it won't fit in any ATX case.

It's not fast even in VGA though and more memory won't fix that.

Should work just fine. There's literally zero difference between 8mb and 12mb versions.
