Voodoo1 in sli is not possible, sli is voodoo2 only (or indeed some quantum cards).

Anthony (guy that makes "new" voodoo cards) has two voodoo 1s running in SLI, and that's who I'm sourcing my cards from. Turns out the voodoo 1 was perfectly capable of SLI, it just wasn't enabled on the original cards.

The Voodoo Graphics absolutely supported SLI. It was just not implemented for consumer-grade cards.

Anthony makes very cool stuff. I would only ask why you would want the Voodoo1 SLI over the Voodoo2 SLI. Best!

I know I know 🤣. It's for a Pentium MMX build so the Voodoo 2s would be held back pretty hard.

Voodoo1 SLI with two texture units each would be fun to play with on a 486 or Pentium system. There will be lots of different configurations to play with to get different games working. Some will run better than a single Voodoo2 and some will run not quite as well, I bet. Let us know your results!

Well the triangle setup engine of the Voodoo II would benefit lower end CPUs a bit. Overall the cards would be bottlenecked, but I think your overall performance would still be higher. SLI Voodoo 1 is a novel enough party trick though and I don't think you'd be giving up THAT much performance wise.

Why do something that's always been done when you can do something that's rarely been done, no-one is building these retro systems for convenience

"voodoo held back" is just a silly phil myth to gaslight others to putting in rages and virges instead based on stupid benchmark bars to "fit the spec" disregarding driver reliability/features and such. They're not "held back" if they can multitexture and blendfunc worth a damn, they were considered the bare minimum for doing just that in a world of better cards (i.e. anything after November 1998)
