I found this link as a reference to start overclocking. http://www.xtremesystems.org/forums/showthread.php?t=205688&highlight=nehalem 101 My system specs are in my profile, the ones on the left. I'm on the first step, finding the max bclock and I'm already failing. The guide states raise bclock incrementally as well as raising vtt & qpi volts. I think one of the three is listed in my asus bios as something else. I'm wondering how much voltage I should allow as I raise the bclock. I've read in other posts base clock can be between 180 & 210 but when I attempted cheat and use the turbo-v and it crashed out at 1.3 voltage & 145 bclock. Is it required to reboot every time you raise the bar? The most important questions you could answer right now are in red. Thanks for any help.
