Nice but VID does not MEAN Current Vcore ... unless at STOCK cpu GHZ.
It took you 1.38 Vcore to get that Overclock.
Nice OC by the way, but like many have stated/claimed ..... stay around 1.20-1.24v to avoid degradation of the CPU.
So that means somewhere around 4.2-4.3ghz .. but again there is no guaranttee that it won't degrade either at those volts, but it more plausible that it won't.
