@ anyone

I have a question about tri-channel memory. Since we all know that Nehalem will allow for 32GB/s of memory bandwidth in tri-channel mode (assuming three sticks of DDR3 1333MHz @ 10.6GB/s each), will it also be possible to run 32GB/s in dual-channel with two sticks of DDR3 2000MHz (16GB/s each)?

The reason I ask is because DDR3 2000MHz sticks are still pricey, and I was wondering if I could get two now and wait for a third down the road.
