IGP Overclocking

Gigabyte GA-MA78GM-S2H Motherboard BIOS

Overclocking the integrated graphics on the Gigabyte GA-MA78GM-S2H has to be done in the BIOS right now as both AMD OverDrive and CATALYST Control Center don’t have any GPU adjustments for this platform. The stock settings on the GPU core clock are 500MHz, but you have the option of overclocking it all the way to 1100MHz.  To reach much over 750MHz you will need active cooling though, so keep this in mind.  We tried for 1GHz, but the system would blue screen while Vista was trying to load.  After backing it down a couple times we were able to get 800MHz stable with no other adjustments in the BIOS.

Image Description

A quick look at GPU-Z 0.1.7 showed that the default clock went from 500MHz (on the left) to 800MHz (on the right).  This is a 37.5% increase in the GPU core clock frequency on the Radeon HD 3200 integrated graphics!

By making one adjustment in the BIOS we were able to improve graphics performance by 16%, which is not bad considering we increased the GPU core clock frequency by 37.5%. With active cooling and a voltage increase an overclock of more than 800MHz is possible, but this is a good example of what can be done with little effort. The Hybrid CrossFire setup was still 13% quicker, but that is better than stock.  With stock settings on the 780G platform the 780G + Radeon 3450 in Hybrid CrossFire was 31% faster!
