Hi will this work if i loop it with the TNT2? Or do i get Problems on the Driver Side? The TNT is a AGP Card and well the Voodoo is PCI.
And if i want to lets say use the better TNT2 for gaming do i need to remove the Loop Cable? Or cann the Voodoo 1 just Passthrough the Signal?
Thank you 😀

Shouldn't be a problem. You can keep the Voodoo inside and use its passthrough. Voodoo will take over when you run glide applications, and TNT2 will be your main adapter for 2D, opengl and d3d. You might want to disable D3D from voodoo drivers so there won't be any conflicts or if games for some reason should prioritize the voodoo.

Beware: Image quality might take a slight hit, and the voodoo 1 does not play nice with machines over 400-500 mhz in my experience.

I totally agree with xpladv570.
Nothing more to add.

Builds:

Xp3000+ gf3 ti200 + vd2 SLI 12MB + 768MB + SB live @ WinXP & 98 Dualboot.

P2 350mhz + Diamond Viper V550 + 3Dfx Voodoo 2 12MB + AWE64 + 128MB SDR @ msdos / win98.

So running on a p3 800mhz wont work? What will it cause? Like what kind of Problems?

And how big is the imagie quality hit?

Thanks for the Help.

Well, above a certain processor speed the voodoo accelerator will be displaying either a blank screen or checkerboard pattern (or other corrupt image) when you will attempt to use it in a 3d application. It is quite interesting because to my knowledge it is the only graphics card that straight up refuses to work on a machine that is "too fast" and i am not quite sure why it does that. Either way, 800 mhz p3 is most likely a no go. A pentium 3 is a rather weird platform for the original voodoo card anyway. If you insist on using a P3, perhaps something in range of the 500E - 600E will work...But don't expect a smooth sailing.

As for image quality loss there is always some because you have a passthrough cable and a bunch of electronics that the original signal must go through, rather than a straight connection from display adapter to the screen. It also depends on how well your TNT is built, some cards have better image output than others.

What if i lets say slowdown the P3, could this work? Its a VIA Chipset Board so ill have 15 slowdown Options.

It's not only the speed, I think it is front side bus related too..
If you use a Katmai, It might work on the max 600mhz. The Coppermine is less certain especially if you use a socket cpu instead of the slot1 variant. The copper mine T has a Frontside bus of 133mhz If I recall it correctly. It is just error and trial. I have seen voodoo1 cards running on 1ghz p3's just don't ask me how. It is very dependent on the mainboard cpu combination you use.

Builds:

Xp3000+ gf3 ti200 + vd2 SLI 12MB + 768MB + SB live @ WinXP & 98 Dualboot.

P2 350mhz + Diamond Viper V550 + 3Dfx Voodoo 2 12MB + AWE64 + 128MB SDR @ msdos / win98.

Well bought a Coppermine-128, Celeron 600mhz, FSB 66 Cpu today cause all my p3 are 133 FSB ones. hopes that it will work.

Well ive saw "https://www.voodooalert.de/board/forum/index. … /&postID=190497"
hope links are ok at vogons.... its german but selfexplaining and it did work with a celeron 1200 out of the box. As i bought a BX board aswell and changing from VIA to BX in case it wont work.
I guess it should work?

I'm looking into something similar, though with a PIII 733. I do have an eye on a Diamond Viper V770. Though I assume this would out pace a voodoo 1?

The Viper V770 would destroy a Voodoo 1. Voodoo 1 in this case would be for (older) Glide or nostalgia to play newer games circa 1999 at 10-15fps @640x480 because you couldn't afford a V770 when new. When you use the Voodoo1, if your motherboard can downclock to a 66MHz FSB your Voodoo 1 would be operating at or near optimal capabilities.

Thanks Meatball, I'm mainly toying with options. At the moment I'm using an old Cirrus Logic CL-GD5446 as a spare. I did have a M64 but it broke. Not bad card. I can get a Viper for $50 with free shipping. Around $90 for a Voodoo. I think it is a Gainward card. I also saw the S550, a tad cheaper but not sure which to go for? I'm mainly playing some glide games, win9x, some Dos also. Just a card with good performance and not too expensive.

Go with the V770. If you get the 55" TV, you'll wish you bought the 65" not too long afterward. Same with video cards.

Besides, the VGA output of the TNT is spotty. You get better video and performance for a little bit more with TNT2. Unless you have some games which require a Voodoo1, or "heck-bent" on a Voodoo1, or want a retro-machine to play games around 1996-97, I would skip it. Save your money and get a voodoo 2, then you have no CPU/FSB constraints. You'll have a heck of a 98-99 system for sure.

Just ordered Voodoo 2 and V770 😁. Will post build in Rig area when parts arrive 😁 Thanks.

Oh the far better choice on this system is indeed a voodoo2 graphics card.
I have a viper 770ultra laying at home too and combined it with the voodoo2 in SLI, in this setup the voodoo cards came close to 70% of the performance of a V770 Ultra on 1024resolution. And some games close to 90%. It's a nice combo.

Xp3000+ gf3 ti200 + vd2 SLI 12MB + 768MB + SB live @ WinXP & 98 Dualboot.

P2 350mhz + Diamond Viper V550 + 3Dfx Voodoo 2 12MB + AWE64 + 128MB SDR @ msdos / win98.

Sounds amazing Aebtdom. Yeah cost a little bit, but shipping was free on both.

FYI, even with a Voodoo 2, you can still experience issues related to speed in certain statically linked DOS games (black screen / out of range / checkerboard patterns). It's unclear if this is a hardware/design issue or a software issue with the way some of these games initiate the Glide API (my guess is software issue).

From my tests, it doesn't seem like CPU speed is the main problem, though, it's more closely related to FSB speed (with the Voodoo 2, staying at FSB100 seems to work great for all old DOS games, while the Voodoo 1 might sometimes need FSB66).

Even weirder is the fact that Voodoo 1 cards can sometimes work with extremely fast systems (with very fast double/quad pumped FSB frequencies), so we're probably still missing a piece of the puzzle.

Maybe you could help. I've installed the Riva TNT2 first then the Voodoo 1 but I only get a 16 Colours mode...or 2.... I have the Monster 3D Options but I can't change the Nvidia ones. Any clue what I am doing wrong?
