Currently overclocking my i7 2600k, ive got it on 4.2GHz which is as far as i want to go at the moment.
My vcore is 1.280v currently, turbo boost settings are disabled as they are not needed for overclocking. The vdroop on the OC is quite big, it drops too 1.200v under load (see below) One of my cores failed also.

My cooling is a Thermaltake FRIO so temps are under 60 even with the fans on the lowest speed, but will notch fan speed up if temps get hotter.
Should i just keep increasing bit by bit or should i use Loadline Calibration, although heard its not good to use or is it?
Thanks
