i have Win 7 64 bit home edition, the 1333 8gb G-skill ripjaw, and the ASROCK p67 extreme4.... for some reason, it is very stable in memtest but constantly crashes to the desktop in every game. I even raised the voltage to 1.545 with stock timings/settings. The factory voltage is 1.50v..... can somebody tell me what I'm doing wrong here? BTW, the crashes happen after like an hour of gaming or more... it's really odd.
