Most SMD caps on these cards are 100 nF / 16V / 0603 size.
Either way, C94 is identical to the one next to it, C88, so you can desolder the latter and measure it.

You can find decent photos of the Voodooo 3 2000 on TheRetroWeb

Thanks,

I have found answer here too. Need to get better at forum search.

I am adding a photo of the board

Unfortunately, the card shows artifacts right from boot.
I was wondering if it's worth trying VBIOS flashing?
I tried pressing on the GPU heatsink while powering on, but it didn’t make any noticeable difference.

Any suggestions would be appreciated!

Regular patterns like this often indicate a memory issue- if the VGA BIOS was corrupt you probably wouldn't have got that far. I suggest replacing any damaged or missing caps and carefully checking whether all the pins on the RAM chips are still intact and connected.

You need to check the contact of each memory chip pin with the pad on the board, gently shaking it with something thin, like sharp tweezers. Some places look pretty bad. And look for scratches on the back of the board that could damage the conductive lines to the memory.
What were the photos taken with? I liked the image quality.

C101 is another 10uF 16V as you noted already.

I’ve used 50V 10µF capacitors to replace all five of the larger ones. Probably overkill, but they fit and work fine for now. For the smaller one (100nF / 16V / 0603), I used a capacitor from an old board. It measured correctly and, while slightly larger, I was able to solder it without issue.

This setup is just for testing—I'll order the original spec parts once I confirm the card is saved. Hopefully, any oscillations in the components won’t be an issue at this stage.

Planning to reflow/resolder the memory contacts by the end of the week.

Photos were taken with an iPhone 14 Pro Max. I placed the card near the window and used sunshades to control direct sunlight.

Thanks all for tips and replies.

Could not find any "cold solder joints" on the card, so I had it checked under a professional microscope. They also didn’t find any soldering issues. However, they discovered that one memory chip is broken and needs replacement. Unfortunately, I don't have pictures. Now I need to find a replacement chip — no idea where yet.
Hopefully, this isn't the end.

These are the chips you want, which are compatible with all SDRAM Voodoo 3 2000 / 3000 cards: https://ro.mouser.com/ProductDetail/454-W9816G6JH-5
As a bonus, these are rated for up to 200 MHz. 😀

Got the picture — not sure how I missed it.
Noob question:
If I replace just one W9816G6JH-5 chip, will it still be compatible with the others, or do all of them need to be replaced?

Yes, no need to replace them all, just the faulty IC.
