Graphics Corruption on Card -> Card Dying?

post #1 of 3
Thread Starter 
Hi Everyone,

I have a 6970 (system is sig rig) that is starting to give me issues. Recently its started randomly displaying snow all over my desktop (at idle) for no apparent reason. It seems to happen whenever I let the desktop idle, but when I start using it, the snow disappears. Thinking this is related to the voltage drop in idle mode, I tried boosting the idle voltages. This seemed to sort of fix the issue, but snow still sometimes appears in significantly smaller quantities.

I haven't changed any software before the issue appeared, and an update to the latest beta driver didn't fix it. Although, the update seems to have made the issue better on the mini-display port output. I have overclocked the card, but it was running stock when the it went haywire, and I never increased the voltages beyond stock.

So, is this card dying on me, or has anyone else experienced similar issues (hopefully with a simple fix!)?

Sounds like it's dying to me, and if the problem shows up when voltage is dropping I think your best bet to make the card last until you grab a replacement is to just lock the voltage up where it runs and get rid of idle drop altogether.

I've always thought that bouncing around between voltages was bad for a GPU anyways. It just adds to the problem of physical stress from thermal expansion and contraction.

That is what I'm fearing. I've set the voltages all to high for now, but it still corrupts some (but not nearly as bad). Is there anyway to stop the card from dropping into the Low power mode? I'm running Linux on this box, so the usual tools probably won't work against it.

I think why the voltage drop happens is purely to try and save power (since that is a big thing these days). It probably doesn't help life time though.
