That setup is pretty close to mine, and I have'nt had any problems with it. I just about any p4 that my friends use. I must say something about the micron ram though... Micron ram and Crucial come from the same company. Crucial is alot better quality though. Micron comes with difreant brands of chips, and very varying quality, while crucial seems to be picked alot better.
The best ddr out at the moment is Kingmax pc333. It also seems to be the only one using 5ns chips, vs. 7ns on all others. (including crucial)
