Phenom ii memory question?

I was reading the Phenom II X4 965 Black Edition: Vitals And Overclocking
article when i read it says "If you're using it on an AM3 platform, you can install DDR3-1333, though it should be noted that only one module per channel works at that frequency."
I didn't really get how that works since i just ordered a phenom ii 955 + 2X 2GB kingston ddr3 1333
So am i suppose to place the memory like this?
ddr3 blank ddr3 blank?
is this what what module per channel mean?

What motherboard are you using? In general you have 2 channel, A and B, so your DIMMs are A1B1A2B2 on most boards, generally to enable dual channel mode you have to put them in both slots of the same color, unless you have one of the boards with 4 black channels, then you will have to read through the manual.

very unlikely
when you get the POST screen is the mb telling you you have memory in a dual channel configuration?

The OP should read his mb manual about where to install the 2 DIMMs for dual channel configuration , but its almost certainly dimm, blank, dimm, blank and should be color coded on the mb

Here is the link to your manual:

It answers your question.

Most AMD boards will have staggered slots, so you can put your RAM in the first two slots and that will be separate channels.
