Step 05 — AMD BIOS: base clock

If your CPU is locked, you can raise the base clock instead of the multiplier. On this board the base clock is referred to as the FSB (front side bus). We’ve returned to the regular multiplier setting of 18, but raised the base clock by 20MHz – a 10% increase. This gives us an effective CPU speed of 3,960MHz, but it also raises the NB (north bridge) frequency by 10%. The north bridge – more properly called HyperTransport on AMD boards – is what connects the CPU to high-speed components such as the memory and graphics card. It’s only designed to run a 2.0GHz, so overclocking it in this way could cause problems. [Click image to enlarge]
