It shouldn't be too surprising to see that the P4R800-V lags behind in memory bandwidth, though it offers a bit more than the Gigabyte 8TRS300M. Even when overclocked, the bandwidth is not as high as a stock i865PE/i875P based motherboards.

Asus P4R800-V DLX (216/432)	48

SuperPi times change greatly with memory bandwidth, and that's why the Asus P4R800-V DLX lags behind even when the system is overclocked.
