Hi. I'm building up a setup with spare parts I got and a mobo someone just gave me. Right from the start I'm telling you that I WILL NOT BUY OTHER PARTS. Mobo: Asrock G41C-S CPU: 775 dualcore E2180 Memory: 3 gigs DDR2-800 GPU: GeForce 8600GT 512megs DDR3 So I want to know what would be the safe overclock on that cpu if I use air cooling only? Thank you.
