Hi,

I just bought a Voodoo5 5500 PCI with a 1.11 BIOS (now on 1.16)

I’m having huge troubles getting the card to run properly and I am very afraid that I’ve bought a dud.

The card works in 2D, both DOS and Win98. However, as soon as i try to run a 3D accelerated game, the screen shows artifacts or a black screen and crashes.

I have tried the card in two very different machines. A SS7 K6-III (no oc) and on a p4 2.4ghz machine. The same thing happens.

I have tried googling but it haven’t found anything that matches my troubles. Any ideas?

I am no expert on the Voodoo 5, but just to get the ball rolling for others to answer more easily, what drivers are you running ?

Post clear images of the card, front and back, maybe someone with expertise can spot visible defects or rule it out.

Ah yes, I thought it didn’t matter since the card doesn’t work in DOS 😀

I have tried the official 1.0400 and the Amigamerlin 2.0 as I read they were stable and good for the v5

Thank you .

Your initial post did not explicitly mention that 3D does not work in DOS . You only said that 2D works in both DOS and Windows 98 .

What DOS game(s) did you try ?

Here are the photos: https://imgur.com/a/5nGgIkZ

For DOS games I have tried Screamer 2 and Screamer Rally as well as Descent 2, but I think the D2 patch is iffy.

In windows I have tried GLQuake, Quake 2, Half-Life, WC: Prophecy, dxdiag test, 3dfx Museum demo and I-war with the 3dfx patch.

Anything else I should try?

Edit: and of course, I am the one thanking here!

Non-update: The evolution 1.01.16_v45 drivers does not help.

On no, I tried it one chip mode, and it works. What a heartbreak.

Do you guys know if it is possible to fix it?

Sorry to read that . I don't know how common the symptom is, but somebody else has a similar issue here . Voodoo 5 5500 AGP only work in single chip mode!

EDIT : If both your cards came from the same source, there may be something fishy going on.

I don’t think so, I bought it off a fellow dane, who had used it in an Amiga.

Screamer games on v5 is hard to get working so no wonder you have problems. Dosglide games can be difficult without a v1 or v2.

In windows try direct3d first on both chips (3dmark99 or 3dmark 2000 for example) also check if both chips work, on the p4 the single chip should be much slower. On the k6 the cpu is a bottleneck for even one chip (is like a voodoo4 4500 still).

A good game with glide support under windows for testing is DRIVER, so try that one as well with direct3d and glide (make sure you copy the glide dll from your 3dfx driver to the game directory)

The 2 purple caps (100uF & 470uF) look like they had leaked all over U13 (SC1175) which is the switching controller.

Don think those solid caps will leak but the card does need some cleaning in that area. Recapping however is never a bad idea.

Also start simple and clean the pci edge connector.

Those leak just like any others. and they tend to cause issues as pointed out with surrounding components. I've seen where people have cleaned up the affected areas and gotten components to work, only to fail again after the cap leaks some more.

Yeah some of them do leak. Here are some that had blown their tops and failed open. They are from an HD4850 GPU that I repaired. Some constructions are not entirely solid but are hybrid, they use a mix of solid and liquid electrolyte.

Maybe try disabling guardband clipping - mine only runs in dual chip mode with that disabled (still no idea why). There's an environment variable for that or you can set it in the registry. Alternatively you can use a 3rd party driver like Amigamerlin which has it in the 3dfx tools options.

Someone at this forum also tried an alcohol bath for cleaning the card. While that may not help with your issue it should at least allow you to have a better look at bad joints. Just make sure you don't use too much as you don't want the alcohol to reach the thermal glue. Like kalohimal said that area looks like the caps leaked there.

For testing just fire up dxdiag and click the Direct3D test, no need to install games for testing 3D mode. Not good news but probably the second chip or the second chip's memory is broken.

Those are Sacon FZ caps, which are chronically faulty liquid caps that eVGA especially was in love with around 2007 or so. They're one of those series of caps that's so chemically defective that they leaked even if never used. Solid caps don't have vents like those do.
The Sanyo Os-Cons pictured on the card though are solid polys of the highest quality. I think the cloudiness in the (very busy) area between them is just flux residue.
