The T case of i7 920 is around 68 degree C. I think you should down clock it to around 3.6 GHz. Although the testing you are using hardly comes in any real life scenario and your CPU will be within the thermal range even with the 1.3 GHz overclocking, still to be on the safer side, just under clock it a little around 3.6 GHz...still 1 GHz overclock which is pretty fine.
But i don't want to overclock RAM,GPU only processor.Will be it possible to overclock only cpu?
I am buying this component in june after that i will provide the CPUZ and GPUZ status as i don't have GF card now(have sold the Hot 8600GT)
