OC Testing

For our OC testing, we have configured our CPU to run 4100MHz on all cores and set the voltage to 1.3875V. This yields an approximate power at the wall of 255w under load (a 197w differential from idle, which pulls about 58w). This results in the CPU running at 4.1GHz on all cores during the looping rounds of Cinebench R20.
