Welcome to the Forums,

If you have DirectX 8 installed, you should be able to see your CPU speed by running DXDIAG.EXE. It may be in your C:\Windows\System folder or your C:\Program Files\DirectX\Setup folder.
edit: I should pay more attention... you said WinXP, so the location is probably going to be much different, oops!
I got the same board/CPU combo but gave the board and my 1.4GHz Thunderbird to my sister. It does indeed report temperatures that sound high (about 53C with an Alpha PEP66 and a 22cfm fan) but it works like a charm. I didn't overclock it. You might want to go into the BIOS and make sure the CPU/RAM are set to 133/133.
The board I got had a surface-mount resistor that was soldered down on only one end, I think it was C100, in the row parallel to the DIMM slots. It stood out visually because it was at an angle, or I probably wouldn't have noticed. Being both bold and impatient, I got out the soldering iron, solder, flux and a bit of copper wire, and I soldered it back down, using the wire as an extra-fine soldering tip. All's well that ends well, I guess...
