AMD has one of the most powerful integrated graphics circuits on the market and the Radeon HD 4200 GPU can be found with the AMD 785G chipset, among other. AMD installed the GPU inside the northbridge and with its 55nm technology the circuit comes clocked at 500MHz from factory. This solution offers pretty decent performance for being an integrated solution, but there is always more to get and that is exactly what overclocker HamidFULL has shown.
He overclocked the GPU of ECS A785GM-M to juicy 1083MHz by increasing the voltage to the northbridge. The voltage for the northbridge houses that houses the integrated graphics circuit has been increased by 0.351V while the RAM and processor has also been tweaked to keep up.
Unfortunately the ECS motherboards doesn't have sideport memory which limits the performance of the integrated graphics processor, but with twice the clock frequency using the regular passive heatsink is impressive. Justing having an integrated GPU operating over 1GHz is pretty damn cool.
