Z68 Extreme3 Gen3 OC help

I have never oc before so I don't want to destroy my new rig. My mobo has the asrock extreme tune program but The manual doesn't say how to use it. Do I turn up the BLCK/PCIE freq? What about the CPU Ratio?

I read the two sticky guides but those tell how to OC through bios not through utility programs. I'm not looking for record braking limits just prob about 4.3ghz or so


I'm running an i5 2500k, ASRock Z68 Extreme3 Gen3, Ocz 700w ps

  1. Go in BIOS and raise the CPU multiplier at 4.2, 4.3 , save and quit. Don't raise the BLCK/PCIE frequency.
