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 ?

Clockgen's Pll is purely for cpu/fsb clocking only. It has absolutely nothing to do with graphic card overclocking.

I would suggest to install the latest drivers from nvidia and re-running the rivatuner with the /build switch to rebuild the database.

And did you select the correct target adapter? In most cases, there is 2.




//Moved to Hardware Q&A

try this software.
http://www.nvidia.com/object/nvidia_system_tools_6.05.html

Yes. Use this.
This is known as Nvidia System Tools(nTune).
Well, it's also known as Official OC Tool from Nvidia. It's light and build-in to your Nvidia Control Panel.
Moreover, it supports almost(99.9%) of all Nvidia GPUs.

Please avoid 3rd Party/Unofficial OCing tools for Laptop GPUs. You don't want your Laptop to die.

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

Nvidia System Tools is Refined nTune because Nvidia didn't develop on nTune anymore and moved to Nvidia System Tools.
Make sure the ratio between Core:Shader is 1:2.5 for your GPU.

Geforce 8M-Series is 1:2 and Geforce 9M-Series are random can be 1:2 or 1:2.5.
