I tried to overclock my E6400 dual core 2.13 ghtz but it would either give me Mobo error beeps, boot up to bios screen then freeze (making me have to reset bios settings manually) . How do I fix this strange instability? I googled my mobo and cpu and it can overclock fine apparently. I upgraded my bios to v1401 (newest) and have a 450 XION power supply... Help??
