I was trying to overclock my newly bought Lenovo G450 that comes with G210M but Rivatuner doesn't seem to let me customize clock speed(only refresh rate/color scheme)... Tried ATITool, 0.24 doesn't detect my card while 0.26 keeps on saying that the card is not used by Windows... Couldn't find the right pll for Clockgen too, any other methods ?

Didn't know that ClockGen doesn't allow GPU overclocking, newbie here

ATITools worked for me... I downloaded the 0.27 beta version, the previous versions didn't work though.

Ntune works too but it doesn't allow shader overclock.

Nvidia System Tools allows shader overclock
