If your RAM is at 1600MHz then it already means your Base clock is overclocked quite a bit and your Uncore multiplier is also increased such that Uncore * Base = 3200MHz. This WILL need voltage increments and you don't know how much your board has overvolted by.
8M in 15.32 seconds. Normal priority, and I did have other apps working, but according to taskman, they were using >1% of the cpus, so...
Wow, you did 8M at a higher rate than I did 1M
And I'm on an E8500, which aren't even that old. Those i7s are awesome.
