GTX 280m Overclocking

I have an Alienware M17x with GTX 280m (x2) SLI and was wondering if anyone has been able to overclock these cards? I'm new to the game of overclocking video cards and have read that its a strong possibility that I won't be able to overclock the GTX 280m. Any help would be greatly appreciated and if this is a duplicate post, I apologize.

Cheers!

You could always try to OC using eVGA's precision which I attached (only worked for me when the laptop was plugged in). I was able to use it to OC my 8600M in my Dell. Just be careful, OCing a laptop component can cause serious heat issues.

ericeod - appreciate the guidance however I already used that tool last night and then also used GPU-z to watch the cycles and noted that eVGA was not able to OC the cards. Any further guidance would be greatly appreciated.

Did you have the cards under load when you were watching GPU-Z ?

I know my card will underclock itself when im just browsing the web,regardless if I have it OC'd or not.This is may be whats happening to you

Deano12345 - No the cards were not under a load. I made the appropriate changes to both GTX 280M video cards, applied the changes while GPU-z was active and I didn't see the cycles change. In fact I noted that while using eVGA the only settings that matched was the onboard 9400 - the two 280's didn't correctly reflect the manufactures MHz.

Do you refer to the graphic or to its slider? Because normall the clocks are about half when idling. That is normal...

If the number on the slider is different than EVGA's, then that is a different story

I wouldn't OC those cards, the cards must be getting hot already (keyword: laptop). Even if the core is not getting really hot, I would think the memory would.

Here is what CPU-z is showing my cards as they have arrived from Alienware.

Unfortunately the NVidia tool isn't supported in Windows 7 - at least that I can find.

Ok - located the NVidia package that will run under Windows 7 x64. Now its time to understand more about the core/memory/shader clock. Any suggestions?
