Yes, I run a Voodoo3 in my cyrix 5x86-120 system, the board is a LS486E, your best bet might be to find a SIS 496/497 chipset as thats what I run.

I got SIS 496/497 chipset. But I ask about 486 not 586 😉

Not sure, I have'nt tested with an actual 486 chip but it also ran fine with a Pentium Overdrive 83

Im sure you already know this but the cyrix and pod struggle to run anything accelerated as it is, do you just want a 3d accelerator or an all in one like a banshee/Voodoo3?

Anything

Anyone managed to run any voodoo card with a 486 cpu?

I've managed a 3dfx Voodoo2 12MB in a M919 w/ AM5x86-133 in the past. There IS a benefit when using it with GLQuake and Activision's 3d games (MW2, I76, BZ), since their software rendering is kinda hopeless on a 486

I've used a Voodoo 1 with an IBM DX2/66 before. Board was a Microstar MS-4145 (ALi M1489 chipset).

I too have run Voodoo 1 and 3 on a 486 board (SiS 496). What CPU you use doesn't matter. What matters is whether the chipset's PCI implementation gets along with the Voodoo.

Voodoo3 requires using older drivers unless you run a Pentium Overdrive. Apparently they required Pentium instructions in later drivers. I don't remember which driver set works.

But you won't find very many 3D aaccelerated games that will run adequately on any Socket 3 CPU. The Pentium OD is fastest for 3D games, especially if you can get it to run at 100 MHz (40x2.5), but it's really a troublesome CPU overall.

Don't expect a Voodoo3 to work with a UMC 888 chipset, at least for all 3 of my boards.

Wouldn't early S3D games (particularly on a stock-clocked 2 MB Virge 325) be relatively well-suited to such a low-power CPU in the sense that the graphics card would be closer to being the bottleneck, at least with visual quality settings and/or resolutions set high. You'd need to set resolution/detail really low for faster CPUs to be the limiting factor, and obviously, you'd eventually hit a point where the card was the only bottleneck. (which, granted, eventually happens to all accelerators)

Or a similar case with a Rage I (or maybe Rage II), or Direct3D games running on the Virge or Rage for that matter.

Actually, it would be interesting to figure out what the best-matched system would be for 3D gaming on a Virge or early Rage, albeit with some variables depending on the specific games compared, detail settings, and drivers used.
It may very well be that a fast socket 3 system would be among the most realistic candidates for those types of cards, as far as 3D game performance goes, especially at default/common detail settings. (albeit, those weren't always the ideal settings for those cards' specific performance envelopes)
Of course, there's also the problematic (or nonexistent) Direct3D and OpenGL driver issues with several of those cards, apart from actual performance limitations.

Don't know what was doing wrong before, but now voodoo1 and voodoo2 work with 486DX25 😀
