No, the Intel/P4 CPU is Multiplier locked ( So is the AMD XP CPU, but it can be unlocked with a little work). the FSB is controlled by the mthrbrd. Aftermarket mthrbrds give you jumpers and bios settings that can raise and lower the FSB Clock Frequency. this is the easiest and most common way of over clocking. Intel mthrbrds don't give you these options, but 3rd party mthbrds using intel Chipsets do.

The ideal Over clocking (for 3D app Tweaking) is a low Multiplier and high FSB even though the result can be a lower CPU Clock Speed. the higher FSB allows more data to be channeled through the Memory, PCI & AGP Bus. Of course Only Some apps will respond Favorably to this. Applications that rely heavy on Floating point calculations (i.e. Auto-cad, etc) and high memory bandwidth (i.e. video editing, Photoshop,etc.) Don't see near the gain with the higher FSB and will favor huge CPU clock speeds and memory pipe lines instead.

More Testing With AMD & GF3 TI200

Default FSB (133mhz) & Video Card (200/460) = 190fps

Default FSB & GF3 @ 240/500 = 200fps

137mhz FSB & Default Vid Card = 220fps

137mhz FSB & GF3 @ 240/500 = 240fps

137mhz FSB & GF3 @ 247/520 = 244fps
