LR has found that it is possible to further improve the gaming performance on AMD 690G motherboards by overclocking the integrated graphics! By adjusting the clock speed of the ATI Radeon Xpress 1250 graphics engine for better 3D performance we were able to get a nice boost in frame rates. If you are looking into getting one of the many 690G based motherboards this is a must read!
After clicking 'Find Max Core' the system shot from 400MHz well over 500MHz and I was greeted with a nice blue screen of death. After I rebooted and started ATITool, I was amazed that the AMD 690G chipset was able to reach 563.25MHz before the system crashed. I manually set the core clock frequency to 525MHz as anything over 550MHz would cause artifacts and that's not good...
