I had that same processor a few years back. The minimum bus speed for Athlon 
XPs is 266MHz.

As far as performance, those early P4s and Xeons werent any real performers. 
My old  XP 1800+ rig with 512MB was on par with a 2.4GHz Northwood P4 
(512KB, 400MHz bus) in most tasks that I could throw at it.

at the time, I have read some threads around the net saying that those 
1.8GHz P4s' and Xeons were in many cases slower than the the Pentium IIIs 
(1.4GHz, 512KB cache).
