Hi everyone, I just have a quick question. I have the older 867 pb, and I just bought a 512mb pc2700 chip although it says i should use pc2100. Would this do any harm. I recently asked my friend and he said there should be no problem, but my girlfriend has a compaq and her's also require 2100, and with the 2700 chip it worked fine but OVERHEATED and then wouldn't go on at all, so she had to send it back to compaq. Thanks.
