Thanks for answering Corazon.
Anyway 1 day untill cpu is oc'd at 3GHz,and run perfectly. ATM I'm with the stock cooler just,and the temps are good with normal work. CPU Temp is 22-26 C. Core Voltage is going up to 1.278 V max. Are this volts good ?
Also I noticed that my RAM freq. is higher now after oc'ing the cpu. From 800 to 889Mhz.
Tommorow I'll move this parts into my other case which is bigger that this and should have better air flow. Also I'll mount one 80,and one 120mm fans there. So the temps should be lower that this.
