I am considering this setup, Athalon XP 2500 333FSB Barton with MSI K7N2 Delta-L motherboard and Kingston KVR333X64C25/512 512MB 32x64 PC2700 DDR RAM. Will this work? Are there any problems with it? Should I get the Athalon XP Barton chip or a AMD Athalon XP 2400 Thoroughbred? Please advise.
With that MB, or any NForce MB, you should get 2x256MB memory to use the dual channel DDR. And I'd recomend something that is CAS2 if you can afford it. If you are planning to OC I'd recomend PC3200. Besides that eveything else looks good.
CAS2 is the <A HREF="http://www.houseofhelp.com/forums/showthread.php?s=d840..." target="_new">latency</A> of the memory (lower the better).
What you are getting is CAS 2.5. Kingston HyperX is CAS2 and so is Corsairs XMS Series. If you are planning on getting another 512 the thats fine to use 1 for a bit, tho depending on what your doing it maybe overkill to get 1GB.
If you are not OC'ing then PC2700 is fine.
