A cautionary tale for OCers..
So, I'd been running it for a week straight. OCd with AB, 940MHz core oc/820MHz mem uc. Stable at 80C per core. Using CCC to boost the power to each core by 4 and 5 pct, 0 and 1 respectively.
Anyway, I decided to take the memory down further. Unlocked AB and took it to 700. No worries. So then I tried 600. Only I didnt type 600, I typed 300.
Artifacts and malignment everywhere. Then it hung. So I turned it all off and went back to BIOS 2, restarted. Soon as windows loads - fan at 100%, frozen. Restart. Uninstall CCC, start again. Now it dies during install. Im tearing my hair out.
I figure CCC has the power settings somewhere that didnt uninstall. So instead of doing it again, I manually delete every ATi and AB file and registry. After which, run uninstall again, and reinstall. With baited breath I waited....
And it worked! Stable, CCC runs OK. (I didnt mention - the only way to start outside safe mode was to open taskmgr and kill MOM.exe before it could do anything.)
So, I start mining again, running AB and CCC. I restore the power settings, leave the memory at a safe 820MHz uc. D'oh. I didnt disconnect the DVD drive I connected to reinstall drivers. Power down, take it out, reboot.
I now have deny all user access to both instances of MOM, and CCC. I'm fairly sure the card memory is fried now, or at least damaged. Its mining at a happy 810Mhash/s right now, I'm scared to game with it though.
Moral of the story? WATCH YOUR GODDAMN FAT FINGERS.
