ASUS N81Vp D2's GPU related question

So as many people may (or may not know)... the ASUS N81Vp D2's graphics card is ATI Mobility Radeon HD 4670 downclocked to a 4650....

So I was wondering how I can clock it back up to a 4670????

I'm a n00b with the whole "overclocking" business so I wanna know how I can do it before I go bustin up the laptop

Man, for a laptop, it has a nice specs but I scored 1360-1370 for the FFXIV benchmark (with every possible fancy Aero stuff turned off).... I'm sad~ T.T;;

But anyways, yea if you guys can tell me what I should do exactly to "safely" (I guess) clock it back up to 4670...

thanks for your help!!!
Much appreciated!!

You can try use RivaTuner to overclock the GPU. It's pretty straight forward. Just increase your core and memory clock speeds 5-10MHz at a time, run FurMark or other GPU benchmark programs until you see artifacts or when your system crashes. Restart your system and select the speed 5MHz less than what you've last tested.

 

so how long should I run the FurMark? Like it may take various amount of time before the graphics card crashes... lol

Thanks
