Overclocking Both GPU & Graphics Memory

Finally, it's time to overclock both the GPU and the memory clocks. Yes, it is quite tedious, isn't it? This is only the case because the GeForce GTX 295 functions like two separate cards. Thus, the overclocking work is twice that of single GPU graphics cards like the GeForce GTX 280 or the Radeon HD 4870.

Ramp up all three (core, shader and memory) clock speeds of both GPU#1 and GPU#2 to their maximum stable clock speeds and repeat the tests with a real 3D game. If everything goes well, the game should run well without crashing or displaying corrupted textures. Otherwise, reduce the core / shader / memory clock speeds until the card's stable.

You can further reduce the clock speeds a little for added stability, but otherwise, you have successfully overclocked your GeForce GTX 295!

Saving Your Profile

The new NVIDIA Control Panel also allows you to save your overclock settings as profiles, which can be activated according to certain rules that you can choose. Very nifty. Here's how to do it.

After applying the changes you have made to the GPU, shader and memory clocks, click on the Save button. A pop-up window appears, allowing you to name the profile that is to be saved. Use something descriptive like "GPU overclock only" or "Full overclock". The profile will be saved as a .nsu file. In this case, we went with the default myprofile.nsu filename.

Name your profile

Select the profile you want.

After saving your new profile, click on the Stored Profiles tab. You may need to click on the Refresh button, but your profile should appear in the list of Profile Names. Just select the profile you want and click the Apply button to activate it. You can also click on the New Rule ... button to create usage rules for your profile.
