hrmmm, if your getting worse scores.. that means something isnt stable... possibly your ram.. or cpu obviously... in most cases.. a voltage uppage should fix that up... just up the voltage a little bit and see if that stays stable.. highest i was able to run my cpu on 3dmark was about 3.6-3.7 ghz... don't remember what i had the voltage at... or my stepping.. lol... but i'm sure you can get more than that
