Dual Channel is a memory access throughput enhancement on the motherboard.
On the D875PBZ, there are two banks of memory - Channel A and Channel B -
with two slots each. By populating Slot 0 on Channel A and Channel B, the
Dual Channel feature is available. If you instead populated Slot 0 and Slot
1 of Channel A, the board operates in Single Channel mode. For best
throughput, all the DIMMs must be matched in speed and size allowing Dynamic
Mode in addition to either Dual Channel or Single Channel. (Four
configuration possibilities total.).

Motherboards that are designed for it can run specially tested paired
IDENTICAL DDR RAM sticks in dual channel mode which doubles the available
bandwidth of the RAM, compared to standard single channel DDR.

Leave off the "specially tested" and you'd be correct...

My original PentiumPro Supermicro board offered two or four way
interleave, can't remember if it was parallel or just to improve
latency. In any case, a bandwidth thing.
