I noticed that the voltage for my FX-6300 had inexplicably increased significantly (I was logging CPU usage in BF3 and the program had voltage displayed). I'm not certain when it happened but it was within the last week. I have it set at 1.4v in the BIOS, which I found was needed for stability in Prime95 at 4.2ghz. It was a little over 1.5v according to CPU-Z, and it wasn't even under a load. I shut it down normally and went into the BIOS, the voltage was still set at 1.4, but I restored the BIOS to its default config and rebooted. Windows was then unable to load, it shows the loading sign for a duration longer than normal before giving me a quick blue screen and restarting. There isn't enough time for me to see what the error is. The BIOS says that core VID is back down where it should be now, fluctuates between 1.36 and 1.4.
I tried checking the PSU with a multimeter, I shorted the 24 pin connector to turn it on, set it to 20DCV and checked the 12V rail on a PCI-E connector. It read 12.35, probably not great but I think that's still inside the safe operating limits, yes? I'm scratching my head, my only other guess is that the motherboard, an MSI 970A-G46 (piece of crap) went haywire. I assumed the CPU would be ok with that voltage, I thought they were rated up to 1.55 or so?
After waiting for a couple minutes I got it to boot from the Windows DVD and did a system restore, which did nothing. I'm convinced it's a hardware problem, I just don't know what. I don't have any other AMD rigs to test components with either.
Just hoping for some confirmation on what the problem is or other things to test, thanks.
