Mmm first post...
Just got a ti4600 but it has a problem. The old user said when changing the hsf two diodes were knocked off. The card is an ASUS v8640. Can anyone work out what diodes these are so i can try and resolder them on? The picture is really poor quality but i don't have the card yet and he doesn't own a camera so he used his phone. If it helps, i can get a decent pic hopefully in a few days but i dont think that will make much difference.

Those look like capacitors... i'd be able to tell you for sure if I still had my Ti4400, but I already sacrificed it to a chainsaw.. ;)

haha, just couldn't resist could you? :banana:
They may be caps, but can someone confirm exactly what they are? Someones gotta have a GF4 Ti card :)

Common guys, i know someone knows what goes here. I got a new pic which is alright quality and i added the numbers of the components.

"c" means capacitor ;)
You could likely bridge right over the solder points without worrying, all they generally do is smooth voltage spikes (if any) on POST or clean RF/EMI interferrence or trace noise (crosstalk) from a trace close by.
Trace pen or solder would work well (trace pen even has some capacitance to it) or a good heavy mark (the more the better) with a pencil.

Thanks but i tried that last night and it wouldn't even boot.

More than likely these are simply decoupling capacitors. I would try soldering in a 1uF cap at each just to give some value to the circuit. Buy them here (http://www.digi-key.com).

Had a few of these lying around so i gave it a shot. It booted fine but had nasty screen corruption. Is the card just borked? or should i try different values? :confused:
