I have a AMD Phenom 2 955 @ 4.0ghz (stock voltage) with heat to spare... Has anyone oc'ed this chip beyond 4.0ghz? and if so what voltage increase did it require? I'm just looking for somewhere to start. I booted up @ 4.2 and it didnt crash out until it was in game so I'm thinking a voltage increase may remedy this problem...?Can someone who has experiences in oc'ing this chip share their expirirences. All input and advice is greatly appreciated. Also does anyone have a benchmark of the 955 heavily oc'ed and how it stands up against the i5?
