Three DIMM Interleaved Dual Channel?

Dual Channel..well i think i might have found a way..

Well here it goes, I have read that if Channel B matches the Size of all of Channel A then Dual Channel will be Enabled!?

So take in turn a board with 4 slots A,A,B,B..If A,A Slot is two 512-sticks.and B is a single Gig Stick it should work?

Well lets see if i can figure out my MOBO..and hopefully someone can help

My Mobo is set up like this Blue,Blue,Black,Black..My two 512 stick are in slots 1 and 2..and are running in Dual Channel.. So i am guessing that my board is set up as followed A,B,A,B

So for it to work my set up should be 512,Gig,512,Blank..

I sure hope this works..anybody else hear of this?

Thanks
