I'd would guess something between 0.1 and 1uF, partly on the grounds that for 10uF they used an electrolytic (I'm assuming that Nichicon replaced a surface mount 10uF can).

Looking at a Voodoo2 component map that was posted ( Voodoo 2 component map ), for that they used 0.15uF near the connector and RAM, so might be worth trying that.

going to try 1uf... on both... guess it not heart....

but my problem can be worse... like... failing gpu..

Oh, I'd have no great hope of it working, normally a single decoupling cap isn't going to make any difference. That said, there was someone else here who fitted a missing cap near the connector to their graphics card and it started working, so you never know.

If you don't have any luck, try posting pictures of the front and back of the card and see if anyone here can spot anything that looks odd.

Does not sound like a capacitor problem.
What type of motherboard and bios is it and how many beeps do you hear ?
Does the computer work with a different video card ?

You should also check the scratches in the red circles. It looks like the solder on the pads is scratched in a way that connects/shorts those pads.
Depending on what signals are on those pads those shorts can cause graphical errors up to a completely dead card.
Check the rest of the card for similar damage.

You probably already know but just in case you didn't: You can usually fix this type of damage by applying some flux to the spot and going over the pads with a hot soldering iron. Usually you won't even need soldering braid.

Edit: I believe the upper circle shorts are all adress lines (which should probably only cause graphical bugs) while the lower circle shorts are VSSQ-DQ29 and VDDQ-DQ31 (which could possibly prevent the card from working at all).

The pc works with other videocards..yes.

The beep is a joint of two different sound beeps togheter.. short ones.. not the classic beep..

Going to check the soldr pads of the empty memorys...

So. I had indeed some solder connecting the memory pads.. take CARE of that..

And installed two 1uf in place of the missing and broken capacitors. I've checked and had ground connectivity on One SIDE so i have instaled the 1 UF capacitor accordlenly.

And nothing..

Same strange beep.. beeeeebipbip

Lol. Cant add videos here

Just to say, i'm using a soltek 65kv2 with via 133a and universal agp.. so.. everything should work just fine

One long, two short beeps is a graphics card error in AMI and Award BIOS. There is another defect somewhere on the card I'm afraid. 🙁

Given the shorts that Doornkaat spotted (good eyes, I didn't see those), could you post some photos of the front and back of the whole card in case there's anything else to be seen?

I give you the links for images with better resolution.

maybe we can figure it out, where to move next... before the reballing, can be something to change before.

You can't just replace any ceranic cap with a large electrolytic. Remove the cap from C105 and C121 and try the card again.
Also what's that brown stuff on C120?

I ment well... obviously i dont know the values for that two caps so i went with a relative safe value. 1 uf.. nevertherless i dont think that will be the cause to the major failure of this card.

My guess is memory failure and/or gpu failure.

that brown stuff is just the left overs of some ruste but superficial...

You're probably right. I was hoping C121 was helping signal integrity on the bus and the large cap was just too much but yeah, some major failure is more likely. 🙁

Is is worth having another look over the board for damage? Have you got pictures of the back of the card? There's what looks like it might be another short on the space for U3. Also might be worth taking the fan/heatsink off and checking for any damage under it.

I'm slightly baffled how there is so much damage to the pads, but apparently so little damage elsewhere.

hmm... actually, it is stange, yeah... the card was taken from a pile of cards at the recicling center.. was not inside an computer.. at least when i grabe it. dont know if it came already loose or was in a computer case..

but the damege in this foto seens like it was beaten, not bits of solder.
