![]() Thinking this was an artifact of Cool'n'Quiet, we disabled CnQ and retested - same behavior. This is where we noticed something interesting, the clock speed would flicker from 3.3Ghz to 4.5Ghz, when a consistent load was applied at all cores. Taking that as our guide, we set the vCore to 1.4125 and started Prime95 stability testing. From AMD Overdrive we saw that the idle voltage was 0.8v, at 3.6GHz it is 1.275v, and at Turbo it is 1.4125v (for both all core turbo 3.9GHz and max turbo 4.2Ghz). ![]() ![]() Switching to the BIOS, we disabled Turbo and headed for a 22.5 multiplier to see if a 4.5GHz clock would be doable. ![]()
