    Intel Core i7 2630QM(2.00GHz) Voltage flucuations, but clock frequency remains the same

    jsabou1

      I got a Lenovo y560p, with a Intel Core i7 2630QM(2.00GHz) processor.

       

      While running cpu at 100% and the gpu at 96% heat becomes a minor issue, which the i7 solves be reducing the voltage from 1.2360V to 1.1259V. The frequency remains at 2.0 GHZ while the temperature goes from 94C to 83C.

       

      I'm using CoreTemp 0.99.8 to monitor the cpu.

       

      My question is why doesn't the frequency go down? When my old T2600 did the same thing the frequency went down from 2.16 GHz to ~1 GHz.

       

      Another question, what happened to "Intel® Turbo Boost Technology 2.0"? Wasn't this supposed to overclock all four cores (when they are being used, which they are, all 8 threads are at 100%). Maybe this is why there is the voltage difference but no clock difference, and CoreTemp doesn't monitor Intel® Turbo Boost Technology 2.0 correctly?

       

      Anyways looking forward to the reason why. Thanks alot!

       

      EDIT: Installed it on and now CoreTemp shows 2.4 GHz Now just for teh volage explaination and why he clock remains the same
