No, is not possible since Sandy Bridge. it will always appear the max stock non-boost clock as the cap even on multi-OC'd CPUs, in fact the task manager it's even unable to display properly the CPU frequencies, it always show erratic numbers on the tenth and hundredth digits. ie, 3.44ghz, 2,89ghz, 3,23ghz, 2.92ghz, 3.09ghz, 3.16ghz and so on, while on CPU-Z it show a correct clock with correct multiplier at the same time. so, task manager is a useless crap for that matter.
