Nehalem-EP......BLOOMFIELD

You're running single channel with 1 stick of DDR3 1066 ?

If so , the results are impossible.If not , the IMC has low efficiency.

Option 3 : memory is running at 1600MHz in single channel mode.

Which one ?

I'd bet on Single channel 1600MHz LOL! Wasn't all 3 channel capable of something like 26GB?

All the SS I've seen of Nehalem have been in single channel mode so far.
Why I don't know but they are.
Maybe a bug or perhaps someone is keeping the systems handicapped until they want the real capabilities of this beast to be shown.
Yea, I heard in the neighborhood of 26GB also.
Cringes at the thought of writing the check for 6 sticks(or more) of DDR3-1333 ECC for a dual socket Gainstown..

Triple-channel 1333 will be capable of 32GB/s.

Ha, Movieman, didn't you see the dual socket motherboards with 18 DIMM slots?

Yea, I saw them..A waste for my needs..1 gig a core more than covers anything I need..

Total of 32GB but usable 26GB just like 9 out 12 right now, right? Current DDR3 boards does 21GB and look how much is usable? Or am I misisng something?

Single channel DDR3-1600 has peak theoretical bandwidth of 12.8GB/s which is exactly what Rightmark is reporting. DDR3-800 in dual channel also has the same bandwidth though.
