I got a stick of 256mb 2700 and I'm happy with it, it's at 163 right now with a locked AthlonXP, the only complaint I have with the memory is that I had to send it back 2 times!!!!  I ordered both from Newegg so I'm pretty positive it isn't Newegg.  First 2 times arrived DOA.  Basically, it seems the people who are lucky enough for it to work are happy with it, but I'd say you'd better be ready to take a BIG risk.
