Overclocking the Infinity SLI and Ultra was a breeze. Leaving my 3800+ X2 at its default multiplier of x10, I had no problem running 270FSB (2.7GHz) stable for a full round of benchmarking. One issue I do want to point out is that although the SmartGuardian program claimed the chipset temperature was only 46C, the aluminum fan housing was too hot to touch.
Dropping the CPU’s multiplier to x9, I was able to hit 303FSB. I feel that with a better cooling solution these boards could scale even farther, but the chipset cooler was way too hot at this point for me to feel comfortable pushing the system any further. I think that simply replacing the chipset cooler with a better after-market solution, these boards would overclock further than most companie’s high end NF4 solutions.
Considering the price of these boards, as well as the performance under a variety of overclocking scenarios, I think these board more than accomplish DFI’s goal of bringing their boards to a whole new audience.
