Is there any advantage to using a multiple of 4 or 8 like 16 GB? (I only ask because it seems like you never see odd numbers like 15 GB of RAM so I was wondering if there was a technical reason for this.)
That's due to how computers work, at a basic level. Memory addresses are multiples of 2 (because binary). Remember the first USB memory sticks? 16Mb, 32Mb and for the really pretentious execs, all of 128Mb of memory [:D]
Like I said, it's preferable to have the same RAM spread into two sticks rather that in a single large one, because it can be accessed faster that way (2 I/O interfaces instead of one). Also, I don't recall seeing a computer with an odd number of RAM slots in a long time, so you'll likely be looking at a 4x8Gb or or 2x16Gb configuration. In any case, RAM sticks come in pairs and must be installed as such (each pair taking the A pair or B pair of slots your motherboard has).
