Which is better : Dual Channel or Dual Channel Interleaved?

I just finished my new build (in my sig) and when I start it up is says "memory runs at Dual Channel Interleaved". Is this better than Dual Channel or worse? For some reason in my mind it seems worse but I've read some stuff that pretty much confused me and it seems interleaved is actually better...

Set me straight please

Interleaving, from what I remember, is organising pages of memory so that the memory controller can treat 2 or 4 like one big page.. No one has really talked about it in a very long time though, so it might not be that!? Anyway, long and short of it is that it's a good thing and you want it on

Quite surprised Intel now finally call it interleaving, they used to call it Dynamic Paging from what I remember..
