P-7805u GPU Overclocking Guide for Newbies

When I attempt to follow this guide, my clocks do not change. I am using Nvidia system tools to do the overclocking. I started with the 715/900/1800 clocks as shown at the beginning of this thread. I hit apply, and I assumed the changes were supposed to be instantaneous, but the clocks, according to GPU-Z, never changed from the 300/200/700 they were originally. I even attempted to play a game and run FurMark to see if that would make things change, but the clocks never move.

Is there something that could be disabling overclocking for some reason? I'm using the most recent nVidia drivers (296.10). I have disabled powermizer, but I have no other tuning software running. I did apply Andros's bios fix discussed elsewhere to help with my driver crashing issue. Could that be overriding everything I'm trying to with OCing?

 

Those aren't the most recent drivers.

Is your laptop plugged in?

 

I can't speak to your specific issue as there is not enough info. I can tell you I would get these weird clocks too before if the video memory got set too high. The only way to get them back to normal was a full power down. Not a reboot, sleep, hybernate or even power button reset.

Now you should remove all OC'ng. get the settings to be fully stock and re-enable powermizer so all is 100% stock for the GPU. Then do a full power down and restart after it cools off a bit. Once the system is normal again then start the tweaks again.............
