I once overclocked my Phenom 9550 from 2.2 to 2.4GHz without any voltage change. The computer booted up the 1st day and then after 2-4 days I played assassins creed. I then minimized the game and then went to surf the net. Then the computer rebooted and then told me that the OC had failed. IS the phenom 9550 that bad at overclocking that I cant even go to 2.4GHz without a voltage change???? Also I have another doubt. I am using an Asus M3A78-CM mobo. The bios says that the CPU temp. is 47-49 degrees. The Asus PC Probe utility says that the idle temp. is 47-49degrees, but the AMD Overdrive utility says that Cores 0,1,2,3 are all around 30 degrees. So doesn't that mean that the total CPU temp. should also be around 30 degrees?? I am very confused which utility should I trust??? Also what is the max load temp for this processor. Also is the stability test software in the AMD Overdrive useful for checking system stability or should I use another software? Which other software do u guys recommend?
