Hey Mike.
I am just running the quads all stock. I'd like to OC them, but since they are not mine, I don't want to toast any of them haha
are you running your's on air?
I'm running all my Q6600's at 3.42GHz (380 x 9) on air with max temps of 50C under 24/7 full Boinc load without a problem - I like to make them work for their dinner
