*REVISED* Just wondering around how high I can overclock my i7 2600k with a Cooler Master V6 GT with a Z68 chipset. ambient temp=20-25C, 4.2GHz OC, ASUS P8Z68-V PRO/GEN3, Corsair 650D (all cables are out of way from air circulation)
Every chip is different. There is no way to tell you without testing your individual chip. So the only way to know is to try. Keep the temps in the upper 60s - low 70s C running Prime 95 and keep your voltage under 1.4v ( under 1.38v just to be sure is best).
