when i did 5-5-5-15 @ 1000 it was at 2.0, i pushed it to 2.1 but still couldnt get the cpu stable. i didnt wanna keep it there either because the specs are 1.8v - 2.0v
i havent really played around with it much. i think i can get my cpu stable at 3.5 with somework. i'll prolly play around...
my e6550 is at 3.3 /w voltage 1.375 stable.. im on a gigabyte p35-ds3r. my temps are 28 idle about 48 load. I was wondering what the voltage on ur brothers rig is, the one running at 3.5ghz
