Do you have the latest drivers?
Try rolling back a single version (If you can?) and try then.

Try backing the memory down a bit. Generally speaking you want Core > Mem OC anyways.

you should try each card by itself ....you may have a card that is just not going any higher

if you could turn your rig info on it would be helpful also....mb and psu for starters smile.gif

usually when the drivers crash it is a voltage problem...strange that even at 1.29v makes no diff.....trying each card seperate will help narrow it down
