By adjusted the CPU Voltage from default 1.3v to 1.4. From 2.0GHZ to 2.15GHZ. Everything seems ok. The idle temp is around 40c and load temp is around 52c. But after i adjusted the CPU voltage ffrom 1.4 to 1.425 watt. And CPU frequency from 2.15ghz to 2.2ghz. The system just crash and show that i need to insert XP cd's coz some files are missing and said need to repair. But after i set the voltage and frequency to 2.15GHZ and 1.4volt. Everything seems fine. So i wondered wut's wrong? Temparature too high? Volt too high? Or???

LPD? MUltiplier? Is it the one with X1-10? Which should i lower it? BIOS?

Whoa great!!!!!!!!!!!!!!!!!!!!!! Thx a lot everyone!!!!! Whoaaaa precious suggestion and guides! I really aprreaciate it!!!!! But then i haven't install any cpu fans. I use the orginally fans from the AMD box one...... Is it fine?

Whoa! It works! Thx Extram Newbie! But the load temp could reach 52c and idle temp is around 42c. So is this normal range temp.? Will it harm the CPU? I set the cpu voltage for 1.4v and overclocked till 2.2ghz...... Is that fine? Or i should raise the voltage? And where can i get those stress test software?

Hey, any software that can adjust my chassis fan speed or CPU fan speed?
