If your motherboard doesn't support enough (or any) FSB settings or multiplier changes, fear not. Most motherboard manufacturers provide BIOS upgrades that may add new features and BIOS Setup options. Also be sure to try third-party software options such as SoftFSB (discussed in the Appendix) to alter front-side bus speeds from within Windows. Finally, replacing your motherboard in order to gain more overclocking options is a viable choice, and can be done for as little as $50. If you do buy a new motherboard, be sure that it supports all of your existing hardware.
