Hi guys!
My new Voodoo 3000 arrived and I want to stick it into my K6 (as I'm yet to finish a Slot 1/S370 build), but I have no idea if this board would have any issues with voltage regulators. How can I check that? I inspected the region around the AGP slot and did not find anything that looks like a linear regulator, so I do not know how to proceed. It is an EFA Viking 3 (P5MVP3-AT), capable of accepting both AT and ATX PSUs (but currently using an AT one, if that makes any difference). What should I do now? The CPU is dog slow (K6-2 366), so I'd probably not stress the card, and I'm only using a Voodoo 3000 because it was cheaper to get it than a Banshee and requires less slots than a Voodoo2 setup.
Thanks!

Your motherboard should be fine, if anything the problem with your motherboard would be handling videocards of later and more powerful nature! I would suggest finding a k6-2 500 for that machine for a good combo 😀 the mvp3 is a great chipset and I really love it. Combine that system with around 128mb or 256mb of good pc100 and a awe32 or sb 16 and you should have a good little DOS/9x system. EDIT: Try OC'ing that k6-2 to at least 400mhz through bus speed or multiplier and it would do pretty well even 😊

If it is the same board as the luckytech P5MVP3-AT it should have a switching voltage regulator and should be fine with a voodoo3. A lot of ss7 boards can't cache more ram than 128mb so it will get a lot slower with more ram and a k6-2. k6-2+, k6-3 or k6-3+ cpu fixes this problem but 128mb should be enough to run any game the cpu can handle anyway.

With a 2mb cache motherboard you can cache more ram.

For stability: disable any fancy agp feature in the bios as the voodoo3 doesn't use them anyway, and put a fan on the voodoo3. No need to overclock the v3 as the k6 does not have enough power to max out the v3.

Overclocking the k6-2 to 400 is a good idea as the 100mhz fsb will perform better. Replacing it with a 500mhz k6-2 cpu won't make a big difference as the k6 scales badly. If you need faster take a k6-3(+) cpu.

Well, I installed it and it is working fine! I'm currently posting from it, using Firefox 2.0 \o/
And it actually works @ 1080p, but the default timings were wonky and did not work correctly... nothing a little bit of Google (and ToastyTech) and some registry tweaking didn't fix. The image is very sharp, and everything is looking good!

Btw, since I don't want/need this to be fast enough to go up against a Pentium 2/3 build, should I rather get a K6-400 or a MMX 233 and play around OCing it to 300+ MHz? I'm thinking about getting an MMX and replacing my Compaq (PMMX 200MHz) as my always assembled retro-machine, as this seems to be a lot more interesting (AGP slot, ability to go past 66MHz FSB, more/better distributed expansion slots, etc.) and easier to tweak, as much as that Compaq has some sentimental value (first retro-PC I bought and my gateway to start collecting and playing around with older hardware)

300+ on a mmx is nearly impossible to get even remotely stable. A 233mmx can do nothing a 200mmx can't do so just take that one from the compaq.
Same goes for the 400, the k6 you have can do 4x100 just as easy. Only thing worth buying would be a k6-3, k6-2+ or k6-3+ as the cache can help a lot in some cases.

For the mmx 2.5x 100 could be stable or 3x 83mhz is a good setting as well. Absolutely max would be 3x100 with a bump in voltage above 3v and a good cooler. Performance wise it would be close to the k6-400 in games.

It will never come close to a p3. A p3-450 is even fastes as a 6-3+ at 600mhz. p3 has a much faster fpu and that counts for a lot in later 3d games.

Take some time to read a post by vetz about voodoo3 compatibilty: a lot of older glide games (voodoo1/2) can work with a voodoo3.

The problem with the one on my Compaq is that it has limited multipliers. I know it doesn't do 3.5x, but I haven't tested lower ones. Will do so to check once I get home. Here in Vogons I've seen a thread where some models are restricted to 2.5 and 3, so I guess it would be fine for those clocks specifically.

Guess I have to install my Voodoo2 together with it, since Tomb Raider has issues with the Voodoo3. No biggie, I just need to clear a PCI slot for it.

EDIT: Scratch that. It doesn't fit (the processor is in the way - the only slot that would fit is being blocked by the cooler I attached to the Voodoo3). Guess that is what you get for using a baby-AT motherboard. Guess I can always play Tomb Raider on my other Socket 7 Pentium machine or the Compaq itself.
