Older mobo -dual channel question

Hello I have an older mobo and i recently placed an order (on newegg of course ) for a Corsair ValueRam 1Gb (2x512) Dual Channel CL2.5 kit

What I am wondering is if my Mobo will support Dual channel:
HP a450n
P4SD-LA Oxford
South Bridge ICH5

As mpilchfamily said, it isn't the ram that makes it dual channel, but the controller. The memory controller in this case is in the northbridge, the 848P. Here is what Intel says about the 848P.

Unless this feature was somehow added, your motherboard does not support dual channel memory. I'm also not sure what mpilchfamily ment by lack of support of dual channel memory with S478 boards, as the 865 and 875 chipsets both supported dual channel memory configurations. (and there are plenty of motherboards out there that have those chipsets.

The two chipsets were the 850 and the 850E. They were both paired with the ICH2. (according to my issue of PC modder.) Doing another search online shows that they were indeed paired with the S478.

I knew when the P4 first came out they were using the S423, and I knew they were also using Rambus. I must be missing a few chipsets....
