This overclocking is new to me,just built my rig last month.here is what i've done so far.4.2 @ 1.2 vcore is stable,I only changed multi and vcore,this change was from an optimized settings.Tried 4.4@1.25 and crashed about a minute on aida 64,stressing cpu,fpu,cache and memory.All of this terminology is overwhelming to me,any help would be appreciated.I'm thinking I have a lower grade chip from what I see from other post.
