Advice on caring for damaged VRAM (5870)

post #1 of 4
Thread Starter 
Long story short; Upon moving house, I stupidly moved my original 5870, together with Accelero Extreme cooler while it was still inside the case, causing one of the VRAM heatsinks to fall off. With the heatsink so close to the GPU cooler, it sat in there and I didn't notice it was no longer touching the chips until 2-3 months later :\\

After 3-4 hours of moderate to high GPU load, the screen would freeze, then show a series of green or grey vertical stripes, requiring a hard reset, and an hour or so to cool down before I could game again....

After re-attaching the heatsink with a rubber band, the system was mostly back to normal, but lowering the GPU clocks to 830/1100 eliminated any and all crashing I've been running it this way for 4 or so months now without issue, and have since found another 5870 on ebay, relegating the battered card down to secondary GPU duty in preparation for BF3

Anyway, is there anyway to repair the damage caused by the overheating VRAM? Failing that, I'm mostly looking for your stories of cooling horror, or any advice on how to care for the hurt GPU

Re-apply thermal tape / adhesive between the heatsink and the chips.

There's no way to repair the memory if that's what you mean, but you can reapply the heatsink using ceramique or another non conductive paste.

In terms of funny cooling stories, I reckon the best I saw was a friend of mine running a psu under a pile of clothes. We could smell the plastics in the clothes burning and thought nothing of it for a few seconds.

When we finally realised and he pulled the psu out, the 120mm fan was running at full speed, and it was LITERALLY like a smoke machine blowing horrible smoke out of the back end

edit: oh yeah and that psu worked absolutely fine afterwards.

Go to a hardware store and buy some thin, transparent type double sided tape.
