So i have overclocked my system for the first time, i did it the "safe" way, increasing the "CPU Frequency" in the BIOS by 1 at a time. It seems like Frequency 200 is 2GHz. So when i reached 220, it was 2.20GHz. But if i turn it up to 221, then the CPU runs at a clock speed of 1.78GHz. I was thinking this could be because i use the stock cooling? If so i need to buy a new cooler (which im thinking to do, a Zalman Fatal1ty should do.) I am at 37c idle with this one now (the stock cooler) Mobo: Asus A8N-SLI SE AMD Athlon 64 X2 3800+ @ 2.2GHz Thx for help.
