I started from scratch (bone stock settings on everything) trying to OC my 3930k. I took a different approach this time, I am using the easytune program in windows to pick out settings and see what the effect is before transferring them to the BIOS for use, as rebooting 155 times an hour got really annoying. I started at my target folding frequency of 4.4ghz and 1.425v to be sure it would run, and I have been working backwards towards the lowest voltage it will run at. I am using IBT standard right now to basically weed out a very unstable OC before I try to run longer/more difficult tests, and I noticed that at a very specific voltage (1.355v) my output time drops by 2 whole seconds and increases by 10Gflops.
I'm wondering if this is the "sweet spot" for this speed on my CPU? 1.350 drops back to 17 seconds and 49gflops, so does 1.360, but 1.355 hit 15 seconds and 59gflops, my temps also drop by 5-6*C per core. Its been a long time since I had a CPU that was so fiddly, and I've never used IBT before so I'm not sure if what I'm seeing agrees with my thought process.
