Do you happen to have other systems to test the card?

Recently I had a Voodoo2 which had much trouble in an Intel 815E based system. The only thing it would ran was the Donut Demo. Worked flawlessly in an older Pentium 200 system with VIA chipset.

No, only this one system, it has the VIA 694X chipset

I'd try some games in pure DOS just to rule out windows/software reasons

atm i do not have any dos games, but what i have found out, only with rightous drivers the card clicks atleast when it is trying to switch modes, all other non righteous drivers do not have it

With nfs 3 i get following picture

And monster truck madness 1, whiplash (fatal racing) and the orchid tool start but freezes and have the same glitches like nfs

Interesting, never knew the Righteous V1 had relais, making the card somewhat mechanical.
My guess those are for enabling/disabling the input and output port.

Does the Donut Demo run with any driver?

which donut demo?

on a rightous cd there was the whiplash 3dfx version, this one i managed to run under dos with 3dfx, it doesnt crash, but still has this glitches, so i think the card has some hardware issues

I contacted the seller and he is willing to refund me the money. was bit lucky i think

BTW how do I uninstall alle the drivers which i have tried out? If I get a new card i want to have a fresh try?

yeah this sort of thing is only going to get worse as time goes on.
im looking for a voodoo1 here in australia and the price is around $200 for a card that has most of the time not been tested properly or not tested at all, and as you know showing a POST screen is not properly testing. If I buy from overseas it is cheaper but then shipping and import taxes take the price back to up near $200, and then what happens if the car needs returning (and the seller actually accepts a return)
if the cards were cheap it wouldnt matter as much, you would take a gamble and if it doesnt work you accept the small financial loss..
instead we are in a situation for 1997-1999 (peak voodoo years) where this one card costs 4x (or more) than the rest of the system.

1 isnt P3 even at 400MHz still too fast for V1?
2 needs refreshing all solder joints and will be fine

no p3 400 is fine, there is a guy here who tested it on even faster p3.

You are safe at 300/333 366 can be tricky...400Mhz and above will likley have errors in D3D. Glide is another thing.

i was testing only glide, no d3d. but atleast it shouls run somehow on 400, but not lock up on every start.

Begin with the visual check of jammed pins and soldering of the chips pins (check it with the thin nail)
Clean the PCI contacts with stationery eraser and liquid cleaner.

The card has 2 scratches at the backside.

Nevertheless, the seller accepted a refund, so i will not spent my time one that one.
