Hi All, I have a g6-2005ax lappy with radeon hd 7670m as discrete graphics card. I want to overclock it as much as possible to play games like BF3 or NFS run at high settings..how this can be done? I have searched many sites and understood that this card can safely be overclocked atleast to 780Mhz. The process is complicated though and includes disabling something called ULPS and then doing some other things which I do not completely understand. Can someone give here a detailed description of the process?
