Make sure you have not set the motherboard to exceed the maximum multiplier setting of your particular CPU. Otherwise it will boot at half its listed core speed and you won't see any performance gains. Also, be sure that the FSB speed setting is correct, and that you've lowered the clock multiplier setting, if necessary.
Double-check that your heatsinks and fans are properly installed and plugged in.
If you're shooting for an FSB speed beyond 100 MHz, disconnect any nonessential peripherals, such as network cards, SCSI controllers, PCI sound cards, and any other components that run on the PCI bus. This will allow you to properly diagnose errors later in the process. Also, change your UDMA IDE HD's mode to "PIO Mode 2" or "DMA Mode 1." This will decrease hard drive performance, but it will help protect your hard drive.
The reason for taking these precautions is simple: PCI peripherals are designed to operate at a bus speed of only 33 MHz (1/3 of 100-MHz or 1/2 of 66-MHz FSB). It's very possible that one, if not all, of your PCI peripherals might become unstable running in a bus clocked higher than 33 MHz. There's a very real possibility that you could lose all the data on your hard drive.
Change all settings in the BIOS to reflect the most compatible environment. All settings regarding the shadowing or caching of the video BIOS or RAM should be turned off. All SDRAM timings should be set to the lowest possible numbers. Set your 8- and 16-bit I/O recovery speeds to their maximum numbers (4 and 8, respectively).
