So lately I have been trying to over clock my AMD fx-6300 from its 3.5ghz stock speed to 4.5ghz. The mobo is a ASrock pro 3 r2.0, yeah, the high quality one... Not really. Anyways, whenever I bump the multiplier up I can achieve a stable overclock to 4.2 ghz without touching the voltage. Here's the kicker, I try to go any higher and INSTANT restart or BSOD. I have tried 4.3-4.5ghz with 3.1-4.2v variations... What can I do to make it stable? I can post a picture of my bios settings if that helps.
