ASUS P6-T: do I have triple channel?

Hi,
My main board is an ASUS P6-T.
CPU is Intel i7 920
Memory is Kingston KHX1600C9D3K3/6GX (kit of 3 X 2GB, total 6GB) 1600 MHz, PC 12.800
I populated the 3 red slots, leaving the 3 black slots unused (as per the manual).

During boot-up, the only information POST shows about memory is:

DDR3-1066MHz
6135MB OK

So, there is no mention about operation on Triple Channel (my previous ASUS boards always showed “dual channel”, etc.)

- How can I verify if I got triple channel or not?
- Why is it showing 1066 instead of 1600?
 
Solution
1) run cpuz to see if it is triple channel or not
2) you have to manually set the speed in the bios, ie the Ci7 usually only supports DDR3-1066, you have to set the ram to DDR3-1600
Tripple channel is controlled by the motherboard chipset. Just fill 3 or 6 ram slots with the same brand and speed of ddr3 and you'll be running in tripple channel. 1066 is the default speed of the ram. If you want to run higher, try setting it manually, or overclock the cpu using the memory ratios (dividers). For my board, I use 240 fsb for the cpu (20% higher than default) and manually set the ram divider at 1:1.66. With the right divider, my ram stays at 800 speed. I use pc6400 ddr2.

Thanks, o1die. But I am still not sure about my two questions. Could you please elaborate:

- How can I verify if I got triple channel or not?

As the POST does not say a thing, how can I be sure?

- Why is it showing 1066 instead of 1600?

OK about the "default speed", but Kingston KHX1600C9D3K3/6GX is a 1600 MHz memory. The main board should accept it @1600, as it is verified by ASUS as a compatible model.

Like they said just run Cpu-Z and select the memory tab and you will get a screen like this.
