->I looked through your manual and I think you can't really go any higher without doing anything that could be considered overclocking *shrug*. You could for example up your fsb to 75 mhz but your memory and everything else may not like it. Don't blame me if you blow up your computer.<- Be careful doing something like that, especially with old boards. I think setting the fsb clock to "no man's land" will set the pci clock (and AGP if you have AGP on your board) to something unusable, unless BIOS locks the PCI/AGP clock to a certain range of values. PCI generally wants to run at about 33Mhz (unless you have a very new board with PCI-X or some such), and AGP at 66Mhz, and these values will generally be a fraction of the fsb. So if your fsb is 66Mhz, PCI will be 1/2FSB. If it's 100Mhz, PCI will be 1/3. Setting it to 75Mhz may cause it to still be in the 66Mhz realm as far as the division is concerned, and set PCI to around 38Mhz, which may cause a lot of problems. I know some BIOS will take care of this by locking AGP and PCI to a certain value, but I wouldn't count on it with an older board/bios. I see no problem with 100Mhz if your processor and memory both support it. Before fooling around with stuff, make sure you know how to clear your CMOS (on most boards there's a little jumper, I think) to the default values, in case you set it to something that doesn't even allow your bios to start.
