The FSB clocks, with my experience, never show up in your Bios. Only the CPU and volt settings are configurable, the memory timing are also available if you have a good mobo. If you have an Award bios ctrl+F1 unlock some hidden features. If no O/C options are configurable in your bios, which is common on almost all notebooks and some desktops, you'll have to use software to O/C. I nice program to O/C your CPU is RMclock. Hope that helps.
