If the server hardware supports interleaving then the 4x8 configuration is preferred. it is also the more cost effective method.

I'll second what SemperPhi said, but keep in mind that more x smaller could be more expensive in the long run if you plan to upgrade at some point - say you have 4 slots and go 4x8=32, then in a year or two you need to upgrade to 64GB, you would need to purchase 4x16, and if you had gone 2x16 now, the upgrade will only cost you 2x16.

It depends on how many memory channels you have, if there are 4 available then 4x8GB would be a tiny bit faster, but if there are only two channels then it's probably identical since the 16GB may be dual rank and the 8GB single ranked for all we know.

Normally servers have 4, 8 or 16 memory banks.  Interleaving with smaller memory chips may be faster, but if you get the latest speed memory chips, and a great set of processors and drives, you probably won't be able to tell the difference between different sized memory chip configurations.
