Overclocking on an ATI Chipset

After testing a few ATi based motherboards from the same Xpress family, we have found that most do not overclock very well. Expectations were thus muted for the ECS RS400-A motherboard in this regard. Starting at 200 MHz I began to increase the FSB of the motherboard slowly... and surprisingly the ECS RS400-A didn't crash immediately. Ultimately, we were able to push this entry level motherboard up as far as 242 MHz, which is a definite improvement over previous boards based on the ATI Xpress chipset family.

The RS400-A BIOS

While the ECS RS400-A uses a standard Award BIOS, the options that are available on the board are quite different from what we're use to seeing. I was not sure how to configure the memory timings so I just left everything at default during testing; there are a lot of PCI Express tweaks for those interested.

There are not many voltage options with the RS400-A. Maximum CPU voltage goes as high as 9% based on the processor you're using. You can increase memory voltage 0.15V and adjust the FSB from 200-510 MHz in 1 MHz increments.
