OC Semi-Unstable after memory tweaking

post #1 of 4
Thread Starter 
So I have been running at 4GHz for about two months now with no issues. So about a week ago I was bored so I decided to play around with memory timings I was able to not a cycle off a few of them and drop the command rate without any real issues. But after some benchmarks, shockingly (sarcastic) It made next to no difference so I put the timings back to were they were before for stability reasons. So now It has happened twice my system will be running fine for hour under load then suddenly AOD, AiSuite, etc... crashes and gets all kinds of Artifacts. This same behavior would occur in the past with some of my unsuccessful OCs, that being said the crashing with an unstable OC would occur right after windows loaded. All the temps are in safe ranges (CPU: 50C VRM: 60C NB: 40C) and my vcore never passes 1.475v under load. So any Ideas what might be causing this? Suggestions appreciated.smile.gif

Have you tried loosening the timings a bit?
