I have assembled new pc few days back. Whose configuration is
->CPU: I7 2600K
->Memory: 16GB (4x4GB) G.Skill DDR3 1600
->Motherboard: Asrock P67 Profess1onal Fatal1ty board
->Cooling: Corsair H70
Yesterday I have decided to the overclocking of system. Since I want to see what is the capability of my system to overclock. While doing this I am facing a problem. Motherboard has bios with the version of 1.3. I have turn of all the c states and speedstepping. OC Tweaking category of the UEFI BIOS there is a speedstepping option which I tried to disable and enable. In Advanced -> Northbridge Category there 4 options which deals with c state. I have tried all the options in it. Tried different combination with enable or disable all the possible bios options available in it.
After all the settings I have done. I am running at following cpu speeds
4.4 Ghz = 1.30v @ 33C idle
4.6 Ghz = 1.35v @ 34C idle
4.8 Ghz = 1.40v @ 36C idle
5.0 Ghz = 1.48v @ 39C idle
I am actually facing problem when I reach 50c temp. I have drop down to 4.2 Ghz when I reached temprature to 55c I have drop to 4,0Ghz when I reach 60c I have drop to around 3.9Ghz. this is really annoying to me. If everything that is speedstepping is enabled still my speed is 1.6Ghz. when I turn on prime95 I will reach maximum temperature.
What is the problem can anyone suggest me solution
