[san080911]

Hi guys,

I overclocked my gtx 560 ti hawk (1000/2000/2200) .. and i really dont know how to set the voltage , so i watched
the following link http://www.youtube.com/watch?v=wBBLJVk8KNM .. and set the voltage .. when i run heavens benchamark
it ran till 7th stage and crashed sometimes 6th stage .... then i swithced to stock mode (950/1900/2100) default voltage..
it ran all the stages without any issues ... does it crasing because of my PSU or m i doing something wrong..?
let me know how to overclock GPU thru MSI afterburner step by step.

AMD phenom ii x4 945
ASUS mobo
8gb Corsair @1600mhz

MSI GTX 560 ti HAWK

the recommended PSU for the msi 560 ti-hawk is 600w, i have had problems even using my ti-hawk with a 550w not overclocked, so look into upgrading to at least a 650w power supply
