I got this last night with my 5870. I overclocked it in ATI Overdrive on Wednesday with the overclock set at 900/1300 and decided to play some Dirt 2, everything was fine that night and i was regularly checking my temperature to make sure it was below 75c (despite it did hit 82c, which i wasn't happy about). Anyway, long story cut short, nothing failed that evening until last night.
I decided to play Dirt 2 again and two laps into my race the blue screen of death greeted me with open arms. I was quite ****ed at the fact it had happened, but i simply reset the computer and it booted up fine. Once i got onto the desktop, i lobbed it back to default settings and went on Dirt 2 again and it was absolutley fine, which means my card was most likely hitting dodgey temperatures (i didn't check my card temperatures when playing last night) and the previous night kind of led this as a suspicion considering it hit 82c.
Yeah, i checked it out last night in Afterburner but there's a problem, i have no idea what the max voltage for a 5870 is, so i don't know whether i'm over volting or not.
Some people are running 1300-1400mv with watercooling, with the stock cooler I'd be incline to stay below 1200mv (stock voltage is 1125mv I think).
i've started getting this in the last week, stock Sapphire 5870 from the 1st batch on release day. 3 Light Grey Screens of death in < 7 days. Nothings really changed at my end , so no idea why its started happening. Win7 64bit
Arent running the card o'cd or any voltage mods, stock bios and its happened in Eyefinity and Single screen.
good point, yes i'm running q6600 at 3.38 but have been for some time without issue ..
