meh, i need to play wow again, left it for a week after multiple crashes on my 4870x2 just messed up my system.
For me, after installing Rivatuner i noticed that with 8.10's and hotfixes, and maybe the ones before at completely random intervals the ati drivers were resetting fan speed down to its lowest and I'm semi sure the driver recovery or full on crashes were caused by overheating. I got smegged off with WoW and tried other games, other games seem to be fixed and in general the system is much more stable since a reinstall, installing just the latest hotfix drivers with no old drivers about and also since I took off the shroud, put a 120mm fan on and dropped the temps by half.
ANyway, just incase its an overheating issue, rivatuner and hardware monitoring, keep an eye on temps, the memory, and shader core can be quite a lot higher than the main gpu core temps that the CCC shows.
I really don't know why it was resetting either, for me I would set the fan speed in CCC to 33% ish in windows, and 45-50% in games and completely randomly, sometimes not for hours on end, it would simply drop the fan to 26% and temps skyrocketed. To be honest i still don't know if thats what actually caused the crashes. Maybe Aero + 3d game is causing it problems, I seem to have a few issues with games not always clicking the card into full 3d speeds for some reason, and sometimes it won't return to stock speeds after leaving a game.
