GPU Overclocking
GPU overclocking adds a tremendous boost to system gaming performance.
Overclocking the two settings that have the most to do with 3D performance and
gaming will increase GPU performance:
3D frequency
Memory frequency
2D core frequency
Overclocking the GPU can be done using NVIDIA nTune 5.0 as shown in
Figure 19. Although increasing 2D core frequency does not affect 3D applications
and gaming performance, the setting impact 2D applications such as DVD
playback.
The GeForce 7900GTX GPU can overclock to 675 MHz to 710 MHz core
frequency and from 850 MHz to 900 MHz memory frequency using the stock
cooling solution. This alone significantly boosting graphics performance. With
water cooling, the GPU can be overclocked further. Be sure to run Stability Test or
3DMark to test the new overclocked settings.
