For example, 2 sticks of PC2700 CL2.5 NON-ECC Crucial RAM, whatever
their sizes, are far more likely to work well than one of the above
with, say, 1 stick of PC2100 Kingston RAM. I am not saying the latter is
doomed to failure, but it might not be as compatible.

That said, Crucial makes some of the most compatible RAM around, you
shouldn't really worry about it.

Hope this helps
