anyone figure this out? same issue here . 300 W psu. did the battery/jumper thing. the jumper next to the battery can only be configured one way or it wont boot at all.

man, this makes no sense. why would 2.1 ghz cpu come up at 1.3?

Makes sense:

-capacitors failing on motherboard due to age and wear
-Failing power supply due to age and wear or too weak.
-CMOS battery has drained, not being able to keep BIOS settings.
-incompatible RAM, e.g if a mix of them is used

Any of the above can cause a socket A motherboard to default to a "safe" bus speed of 100MHz,
where it at correct conditions would POST at 133, 166 or 200MHz, depending on the CPU model.

I realize this reply is to an old postilng, but perhaps the following information will be helpful to someone currently looking for a solution to the processor speed problem with the AMD Athlon XP-M processor series.

Go to the Device Manager and check the Properties/Driver details of your processor. the driver should be AMDK(?).sys.

If the Version number is 1.1.X, that driver series has a problem. (On my computer, Windows was reporting 400mHz processor speed for a 1.6 gHz processor...and the computer response was like molasses).

You need to get the current AMD driver for your processor. For my 3000+ mobile Athlon processor, the version was 1.3.2.X (8/07).

After installing the AMD processor driver update, the processor speed was reported correctly and the system performed as it should.

Go to http://support.amd.com and download the current AMD driver for your processor.

Socket A processors(if that is what you're talking about) stopped being produced in 2005. XP-Ms(M for mobile-laptop) were never designed to run in desktop pcs, although most desktop boards will run them. The low-speed problem in your case is related to the cpu multiplier rather than the motherboard fsb which is covered in this topic.

Let's be clear about why a desktop 333fsb xp3000 runs at 1300 MHz instead of 2167 MHz. It's because the motherboard has defaulted to 100MHz bus speed when it should be 166.
Multiplier 13.

100Mhz bus - 13x100=1300
166MHz bus - 13x166.66=2167MHz.
