I have that card also, I could dig it up tonight and see if we can get any wiser?

That sounds great, thanks! From what i can understand the color gives out the Farad rating and the size of the cap the voltage.

I highly doubt that the missing cap would do any harm.
Anyway, just add a generic 47 or 100nF cercap in the corresponding package. You can get them as spares from nearly every pcb nowadays.

Of course it shouldn't be a problem to run it but i'm not in a hurry to run the card. I'd rather run it with the capacitor soldered, I mean they've put the cap there for a reason obviously 😀
Probably the white ones are 10nf and the brown ones are 100nf. The small caps like the C51 and C52 are rated for 16v correct? If C56 ends up being brown i'm just going to solder a 100nf 16v cap in there.

110Mhz RAM on a Voodoo 2 is pretty rare indeed. Definitely worth fixing. 😀

For what its worth, I've replaced components like that before. I just harvest something that looks very similar from a similar type\era of card and I've never had any problems doing this. Only had to do it a few times thankfully, because soldering things that tiny with an iron can be a bit annoying.

Don't you need those tweezer irons for this?

Yes, you do. I'm lucky that I got the last one at my computer store since my plan is to check the SMD caps on my ASUS laptop (not retro) for any lost uF, and replace caps or chips, such as the YMF262M, for example on older sound cards.

I'll just replace the iron tip for a tiny one. I might ask a friend for some bad hardware from that era to desolder some caps. The problem is i only have the good stuff 😜

I'm sorry, I wasn't able to get the card this evening. Hopefully tomorrow!

Okay, found the card(s). They were in a build I forgot about. I have two Trust Voodoo Dragon 2 cards, one with 100MHz memory chips and one with 110MHz memory chips.

C56 is light brown on the 100MHz one, and dark brown on the 100MHz one. PIcs:

100MHz:

110MHz:

Interesting to see, I have 6 Voodoo2 12MB cards, they look pretty similar at first glance, but the details vary wildly. I also have one with no memory chips on the back, just on the front. It says 12MB on the board.

Take heed and capitalize the "I" no matter where it appears.
Just funny. I can't speak proper English, but here I am, giving lousy lessons in moral. 🤣
I just thought was important (I made this mistake in the beginning out here, too).

Alrighty, we got something in common - three capacitors missing in my Voodoo 2. But even so, my card is working like a rock star.

Brown ? Like so ?

(3) 100uf 16v is all that I need ?

Are you listen ? If something happens to this card, I'll go ballistic 😀
Please, show me the way. And although it's easy for me to replace those tiny SMD caps nearest modern GPUs, I can't fix this!
I feel trapped.

Yes, they do. I noticed mainly rearrangement of caps and resistors.
Still, my card (CT6670) lacks plenty of memory chips (there are caps next to the empty places, why are they here?
I assume, in reality that cap from the top of my card is redundant. There are only two caps pendent).

That said, the card I posted is evenly matched with my model: CT6670 (8 Mb, I think).

Thanks for the pics! I'll just try to find a used cap with the same color as the 110mhz one from late 90s cards. It is a bit strange they used different cap even though they are the same card, only different memory frequency.

Edit:
On the other hand they might be the same value cap, just different color because the large caps also have a darker color. Maybe different brand/revision of the caps? I don't know.
