Step 3, Enable driver level overclocking
Step 4, Select Performance 3D in the dropdown menu
Step 5, Increase the Core Clock speed by 15MHz, then let it run the stability test, then apply the overclock.
Step 6, If it passes the test and allows you to apply the overclock, run your favortie PC game for around 15-20 minutes
and look closley for any artifacts or any visual distortions that shouldnt be in the game
Step 7, If you see no artifacting or distortions, then in Rivatuner, increase the Core clock, by another 15MHz
then test it, then apply it and run the game for another 15-20 minutes.
Step 8, Do this until you notice visual aritfacting/ distortions
Step 9, Once you notice them, open rivatuner, then turn the Core Clock down by 20MHz then test and apply them
Step 10, repeate the steps above, but this time, do it for the Memory clock
Depending on the card, you can get a major performance increase in most games
