Did you use a 2D VGA card in conjunction with the Diamond Monster 3D? The Voodoo Graphics (and Voodoo II) are 3D add-on cards.

No, just Voodoo alone. Do i need to add another VGA card to PCI slot for voodoo to work, or did i misunderstood You? I have never own a Voodoo card before, and i don't know 🙁
This is the card i tried (in attachment)

Of course you need a graphics card, no need fof it to be PCI it can be any random and cheap AGP one.

You need another 2D capable graphics card; Voodoo 1 and 2 were 'only' expansion cards that took over the 3D part. Typical and contemporary choices would be cards from Matrox, Nvidia (Riva 128/TNT/TNT2), or S3 Virge. The two cards are then connected via a loop cable, and the monitor is connected to the Voodoo. In 2D mode, the image is then passed through the Voodoo to the monitor via the loop cable.

Ok, officially, i'm an idiot!!! I didn't know that, and of course, when i added another Graphics card, it worked perfect!!!
Thanks a lot, i should ask this question before, it would save me some nerves 😀

Voodoo1 is speed sensitive, around 500-600MHz is where you start getting into trouble

I had one running fine on an athlon xp@ 1000 (geode) with a very late model (~2008) sis chipset.
The same card failed to work on another earlier sis board and an axp @1150.
I suspect the chipset is the issue more than the cpu speed.

Nah, it wasn't Athon that gave me troubles, it was my "knowledge" about Voodoo cards 😀

What rasz_pl is saying is that you should be mindful of your CPU frequency. From my experience, Voodoo 1 runs just fine on anything up to 300 MHz or 66MHz FSB in general, but as soon as the FSB is raised to 100MHz or you start going south 450-500 MHz, all sorts of weird glitches start showing up. Keep that in mind, as you may need to move to a slower system, typically any of the early Pentium II or late K6-2, III and + CPUs will be more than enough to push as much out of the card as possible.

Ok, thanks.
I was just testing the card in that mbo, because it was on my table.....
I'm going to put the Voodoo into 486 - 133MHz computer 😀

That would be way too slow for the Voodoo 1. Consider that it was aimed at Pentium 133 - 166 and it scales pretty nicely all the way up to early Pentium II systems. Performance will be pretty bad on a 486 of any kind, I would recommend a different system for first time users.

I second the recommendation to use a Pentium instead of a 486.

The Voodoo was best for games from 1996 to 1997. You'll want a Pentium or Pentium MMX system to get decent performance.

Ok, if i'm going to be disappointed with performance of my favorite AMD, i will choose Pentium 😀

Again, mine was absolutely fine on AXP 10x100
