RAM. What is interleaved memory?
RAM dual channel inter leaved
A basic explanation of Interleaved memory is, the memory on the motherboard is accessed as if it is one large block of memory e.g. the 2 RAM modules act like they are 1 RAM module. This reduces access times and gives an overall speed boost.
Mixing memory types/speeds/etc will result in slower memory timing speeds (lowest common denominator) and certain functions being disabled if memory sizes are mixed. The reason for this is that memory interleaving is a sort of 'computer math trick' that allows the RAM to have faster throughput if all of the memory address' align (which means the sticks would have to be at least the same sizes). Your motherboard/chipset combination will determine what your limits are based on the memory types you put in, in other words, memory functionality (dual-channel/interleaving) is a function of the motherboard/chipset you use and not necessarily of the RAM itself. If you have 2 sticks of 4GB (2x4GB) in slots 1 and 3 (usually how it goes in dual channel) they should be of the same type (speed/latency/etc.) otherwise the RAM won't 'work' at all (won't be recognized) or the RAM will 'run' at the lowest speed of the two. Mixing the sizes in the banks (2x2GB and 2x4GB) should keep the 'dual-channel' configuration if that's an option in your chipset and the dual sticks are the same (i.e. speed), but it could depend if you will still have memory interleaving as that is an algorithm employed by the chipset manufacturer which uses 'banks of memory' (could be the entire stick or a few chunks of it).
If you are only doing basic (not video/games) web surfing, and document editing, even some power stuff may not understand the performance difference. But if you are a gamer, like watching lot of videos, do any sort of virtualization, are an enthusiast, graphic designer, video editor, etc. then memory interleaving 'could' make a significant difference to you.
