Both boards offer the possibility to operate the front side bus beyond specifications. The BIOS offers extensive adjustment variations, while the Asus CUV4X-D seems to be user-friendlier. Since most Pentium III processors are equipped with a fixed multiplier, the processor can only be overclocked by an increase of the front side bus clock. For this purpose, both boards offer finely adjustable clocks for the FSB. Optimum cooling of the CPU allows overclocking the FSB to 150 MHz, which produces a processor clock of 1125 MHz (7.5 x 150 MHz = 1125 MHz) in case of the Pentium III/1000.
