The issue here is that you have to populate what Intel refers to as slot 0 in each of the channels first, as otherwise the system won't recognize the memory. This shouldn't be too much of an issue, unless you're using some exotic kind of CPU cooling that takes up too much space and prevents you from putting your memory modules into those slots.
This is all related to a minor bug or errata as Intel likes to call it in the first generation of Nehalem/Bloomfield processors, but it should be rectified down the road as Intel didn't have enough time to fix the issue straight away.
