Need help determining capacitor value

[[email protected]]

I got a trashed unbranded (probably Chaintec) nVidia ti4200, which is
missing a capacitor. Believe it or not, the card is still running, but
in Windows, the screen is all messed up (vertical stripes and
corruption). I hope this is due to the missing capacitor, which could
well cause underpowered memory chips.

The card is a reference design. However, I have been unable to
determin the value; it's the only one on the board. Here is a picture
of a similair card. The value I'm after is that of the purple
aluminium electrolytic capacitor on the top right hand of the card
(C2267). This is the only pic I could find, and I can't read it

If anyone knows what value it has, or has a suggestions for
alternative parts, please let me know.

I'm betting it's probably the same value as the other caps. Ballpark
guess, I'd try something like 10uF (at least 10volt rating). Might be
as high as 100uF.

BTW, I just looked at a video card I had in the drawer and the filter
caps were all 100uF, 16volt.

If you enlarge the picture, it appears that cap has the following markings on
it:

224
???
82
16

Not sure what the section I put ??? is..looks like letters to me, but I can't
be sure. I think this would make it a 16 volts cap, 84uf or 224uf? Someone who
knows how to read these can tell you for sure though.

I think it is 82uF 16V.
