How do you do asynchronous dual channel on a DP965LT

All I can find in the board desktop guide says I would have to add a third dimm equal to the total size of the original matched pair, i.e. a 2 gig dimm if I have two gig in the original two chips ---what's the straight skinny?
 
I have beat this one over the head a dozen times.
channel A must equal channel B to get interleave
but I think you can get async with just channel A bank 0 and channel B bank 0 with the same dimm size.

Ideally you want interleave. Right now I have 1.5 gigs in A and 1.5 gigs in B and it runs dual interleave just fine.

It's more specific in that.
 
Thanks XARICK - this is indeed a puzzle for my head. But what I think I understand is this - if I have interleave with 1 gig in channel A bank 0 and 1 gig in channel B bank 0, I can't get an asynchronous 3 gig by adding another 1 gig stick to channel B - nor can I get interleave - is that right? Or is asynchrohous another way of saying "Flex Mode?" Or is asynchronous the same as Intel's Asymmetric? Sounds the same to me.

The board technical product specs seem to leave a lot unsaid. In their illustrations, they keep saying ". . . in this example . . .". Could that mean that other variations on the illustrated theme may work? The only thing they say for sure - are adamant about, is channel A dimm 0 must be populated.
