If it's a matter of AGP compatibility problem, you could always go for the V5 PCI and use it alongside an AGP card. Well, in theory at least... those cards are being hoarded like it's the end of the world *clears throat* 😜

Most Pentium 4 boards require 1.5V AGP support if they're going to be used with an AGP card, and Voodoo5s are 3.3V. You can go with a PCI card or find an AthlonXP board that will support 3.3V. According to Dodge Garage the Epox 8K3A+ will work, as should other boards with the VIA KT333 (looked up a few on ebay and they appear to have AGP Universal slots).

So Pentium 4 systems don't support 3.3 V anymore?

What about late Pentium 3 Tualatin compatible systems?

My understanding is Pentium 4 never officially supported 3.3V AGP - I remember reading some conspiracy theory about how Intel had colluded with unknown dark forces to end 3dfx by removing 3.3V support starting with the 845/850 chipsets, no idea if there's any merit to that though. I don't think I've ever seen a Pentium 3 keyed for 1.5V only.

Well the manual doesn't mention anything:

The AGP slot has no keys at all.

Is there a performance difference between the AGP and PCI version of the Voodoo 3?

That's a universal AGP slot - it should work with 3.3V or 1.5V cards (universal AGP slots are supposed to).

Here are some benchmarks which test how a Voodoo 3 PCI responds to overclocking the PCI bus. Doesn't seem to matter much.
With a Voodoo5 it will matter to some degree.

Looks like I should go for a PCI version so I can test in the a Pentium 4 as well. But looking at some test it appears that the Voodoo 3 2000 is exactly as fast as Voodoo 2 SLI.

I would get a V5 5500 PCI just to have it, but not for Pentium PRO MMX 300 it that even excists.?
Is it a overdrive cpu? or a old PPRO or a PMMX at 300?

I assumed that "Pentium Pro MMX 300 Mhz" just means a Pentium II 300. I think some old tools output that description, and it's not actually that wrong.

V4 and v5 cards are very benefits from 66mhz bus speed. No matter pci or agp. On 33 MHz bus perfomance significantly degrades. There are exists 3.3 to 1.5 agp adapter. Or you can try to mod card to 1.5 on you risk

Here is the compatibility list for Voodoo3, should be the same for Banshee and Voodoo 5. Yes, all the most popular games will work:

v3 pci vs v3 agp is about equal in performance, but v5 is a different story. And yes, v3 2000 is on par with v2 sli (with better image quality).

I tested my v5`s on my 1,4 tualatin and the agp version is 20% faster.... on a slower system ofcourse they become more and more equal and on a faster athlon xp system i expect the gap to become even bigger (will test that soon)

I think that you can use a v5 on a 800-1000mhz system perfectly fine if you use the AA option. If you don`t or have a slower system imho a v3 is a better option (and i a nice allround card for very lttle money)

Really cool chart. I was trying to play Archimedean Dynasty a few months ago on my V3 and looked very weird. Initially, I thought this was how the game was supposed to look but now it all makes sense!

Yeah, they're SUPPOSED to, but would you take a chance with a Voodoo 5? I'd try booting it up with some crappy old 3.3v card first that won't be such a big loss if it burns up.

I'd like to take a second to point out The Dodge Garage, to anyone who may not be aware of all the 3DFX equipment and prototypes therein.

I generally wouldn't be using hardware that I hadn't tested completely, and I absolutely agree with your reasoning - always better to verify stuff will work with "disposable" parts before jumping in headlong with rare/exotic hardware. I'd also probably test a new-to-me Voodoo5 in some crappy motherboard before putting it in a main system just to protect both sides. 😀

I will add that I've never had issues with my 815 board and its universal slot, so the function does work somewhere. 😊

I was wondering about that, too. Aren't the 3.3v and 1.5v slots keyed completely differently? Well, I mean you could take a file, and try to shave off a contact to force it to fit, but still...

Yes they're keyed differently, and they have different signaling voltages. See here for more in-depth: http://www.playtool.com/pages/agpcompat/agp.html

I'm guessing you can get an "adapter" for this just like you can get "adapters" that make HDMI into VGA or whatever other nonsense. Very few of these abominations ever work, and in a lot of cases can cause damage to one or both devices used in the attempt (the "funniest" one I've seen recently is a "FireWire to USB cable" - 🙄).
