Overclocking issues with p67a-g45

Question

I am unable to get a decent manual overclock with this board. The OC GENIE overclock is about the best stable OC I can get which is only 4.2ghz and this processor should reach much higher. Anyways here are my specs:
i7-2700k
2 x 4gb G Skill 1866 9-10-9-28
Gigabyte HD6850 OC
2 x Vertex 3 SSDs in raid 0
700 watt PSU
Thermaltake Frio CPU cooler
P67A-G45 Mobo
I've got the newest version of the Bios-5.3 which I've been unable to find much documentation or guides for. Any help would be appreciated!

Answer 1

Basing on experience, the latest bios are only best used when running Ivy Bridge cpu.  With my i5 2500K before, I didn't have any issues overclocking it at 4.3ghz [Auto V] using official 1.J0 Bios until I upgraded to 4.xx bios.  I couldn't overclock it at all.  I went back to Bios 1.J0, problem solved.  Since your using Sandy Bridge cpu, I suggest you do the same.  I am using P67a-GD65 which is simply an older brother of your board.
Btw, my settings when I was running i5 2500K.  Hope it helps, good luck!
