strange powder on my card

post #1 of 5
Thread Starter 
Alright, so after some help in another thread and the replacement of my previous graphics card, a Sapphire Radeon HD 6870, which I thought was damaged from an OC, may not be damaged. I found the error to be in a stick of RAM, which now leaves me with a card that may not be fried. The only thing that makes me question its state is this strange powder I found on it, does anybody know if this is a normal occurance or result of some damage?




Thank you all for your assistance.

were the ram chips completely covered by the cooler? If not could it just be some dust?

The only components likely to spew anything out if they get damaged are the largish can-type capacitors. None of those in the photo seem to be bad (they'd swell up and have leakage if so).

Hmm, well I certainly feel silly. I think that may be a pattern blown onto them by the copper piping, the cooler isn't entirely covering the chips, but the piping is, maybe blown down on it by that pattern?

Dust is much better than a blown capacitor thumb.gif It can get everywhere. Airflow doesn't need to follow straight lines so it seems the most likely to me. Does the spacing match up with any of the heat pipes in the cooler?

Did you have to clean off dust from elsewhere on the card when you tool it out?

Did you have to clean off dust from elsewhere on the card when you tool it out?

The angles it came off look strange, but the spacing would seem consistent with those of the pipes, but nowhere else had that much build up, light particles, but nothing like that, which is what really through me off, along with the way it felt compacted together while cleaning it off, made it seem more like a form of corrosion to me. but thanks for the help!biggrin.gif
