Running at 1.3v it seems stable, I could only get a two hour stress test while I was away, but tonight I will do a full twelve hour test. I guess the lesson here is that voltage can increase stability, but if it is not needed for immediate stability, then it doesn't necessarily need to be raised.
I have another inquiry though, when looking in cpu-z I see the multiplier bouncing between x9 and x6. I'm assuming that it is bumping down to x6 while the system is idle or under a certain load threshold. Is there a way to lock it in at x9, and if so, would that even be a good idea at all?
