Overclocking

[obxdude018]

Ok, I'm trying to get my overclock up more than what it is, it may not be designed to go any further, but we will see, ok I have core voltage set at 1.44 volts and the cpu oc'ed to 3.8ghz, last night I tried to bump it up to 4.2ghz and the computer restarted, but didn't load bios or nothing, it just stayed with a blank black screen. Is this a matter of not enough voltage or just can't push it further.

You need to go in smaller increments. If you are stable at 3.8GHz, try bumping your multiplier up to the next stage and test for stability. 400MHz is quite a substantial jump to expect stability in that range. When you get instability after bumping up the multiplier several times in small increments, then increase the core voltage to the next increment and try again. The key to obtaining a great overclock that is both high and stable is patients and lots of testing. You have a good platform for overclocking, just slow down a bit and take your time and you will see some awesome results.
