If you’ve decided to get a motherboard using the 780G chipset with its integrated HD3200 GPU and don’t have any money left over for a dedicated graphics card, you’ll be glad to hear that there is a very simple way to get more 3D performance. At stock speeds, the on-board GPU runs at 500 MHz.
Pressing CTRL+F1 in the BIOS of the Gigabyte GA-MA78GM-S2H motherboard opens a hidden menu that allows you to change the GPU’s clock speed. We were able to boost our sample’s GPU frequency from 500 MHz to 950 MHz. All benchmarks ran much faster and completed without errors or crashes.
| Benchmark | Performance Increase |
|---|---|
| Warhammer: | 21.7% |
| Supreme Commander: | 42.8% |
| UT 2004: | 18.4% |
| Serious Sam 2: | 47.1% |
| Quake 4: | 22.3% |
| Prey: | 21.8% |
| Average Overall: | 29.0% |
We were able to achieve a performance boost of 29% by overclocking the GPU to 950 MHz. The 55 nm process really pays off for overclockers here.
