|first of all download evga precision.|
intsall and run it
then u will have 3 clocks core, memory,shaders,
raise each one by 5-10MHz then apply and keep testing the toughest 3D game u have.
once uve overloaded the card and went offboard with the overclock u will see artifacting(snow like dots) in ur game or the game is not stable directly shut it off and reduce the clock speeds by 15MHz or so.
if u dont want to run a game each time, u can download atitools and stress test the card for artifacts this should be more time profitable than a game. in atitools when u start seeing artifacts reduce the speeds by 15MHz.thats probably it
computers are a second home
