Kay..we're talking about memory interleave here.

Google for: memory + interleave

Lots of stuff. Most relevant is the page at http://www.2cpu.com/Hardware/mem_interleave/

The short answer is that IF your mobo AND your memory will support memory interleave AND you can enable it you MAY gain a bit of speed from this. Probably not worth the farting around unless your're a dedicated hacker.

You'll have to research the rest yourself. Interesting
