Ok I have had this board for a few months now and never got around to OC it until now. I have say first off I am a amature at best so if this is a dumb. I oc my i7 920 to 4.2ghz. the thing I notice is that cpuz shows it at 2.6ghz until I start prime95 and them it jumps up to 4.2ghz. so when running different programs my cpu speed go up and down. So is this a feature of this board? can I turn it off in Bios so it will run 4.2ghz all the time?
