Unfortunately in german language (a nice translation might help) is a nice article @ chip.de which shows how to get some Athlon XPs to run with a 400MHz FSB clock. Here's the link.
Important part is...
... to get an adjustable resistor of 1 KOhm, the CPU and an nForce 2 board along with some tools to solder and work with. The adjustable resistor is soldered onto the board onto the piece on the left above 1st DDR bank named/ labeled "3037A" as shown on their pictures (first and last). Next glue the adjustable resistor to the AGP slot at good reach and set the system up with CPU, ram and cards. Power on and enter the BIOS. Under "Enhanced Settings" set the FSB clock to 200MHz and set the CPU multiplicator accordingly. The AGP frequency should be set to 66MHz and the DDR ram clock to 200MHz. Now goto "Voltage/ Frequency" and raise the CPU voltage to 1.75 till 1.8V and the DDR voltage to 2.9V (highest possible). Finally goto "PC-Health-Status" and make sure that you slowly raise the Vdd voltage to 1,76 Volt via the adjustable resistor.
Take care because as always you do this on your own risk. However it seems results are looking good and now head over to take a look @ those pictures and benchmark results.
