I don't know if this is motherboard specific or os specific info I'm going to give you. Usually you want all your ram to be as fast as your buss speed or higher, error-correcting or non-error correcting, which depends on your motherboard. Get the error correction wrong and you're fried. Of course the most obvious thing, what does your motherboard support for total ram and what does it support in each slot, I think that sometimes matters. I don't know what distro you use, or if it matters but the debian installation manual has a note about expanded vs. extended memory in one of the first 3 chapters.
