I suggest you do NOT use nTune...It is very buggy -

Heres my guide -

You will need -
Lots off free time
EVGA Precicion (You will have to sign up)
ATITool (Works on nVidia too)

First open up evga precision. There are 3 sliders. One is core, one is shaders, one is memory. First click the Unlink clocks button. First start on the core. Open up ATITool and click 'Scan for artifacts'. A window with a pink fuzzy thing will open. Then in EVGA precision slowly move the core slider up. STOP when you see any small yellow dots (These are known as artifacts). Record the hightest point you got to. Once you see any dots move the core slider back down 20mhz or so. Next do the same with shaders and memory. You may have to back the core down a bit to get a stable overclock on all three. Finally to check it is completely stable run the ATITool artifact scanner for at least 30 minutes, check carefully to make sure there are NO yellow dots or errors displayed at the bottom.
