Whats the go with Dual Channel RAM

hey im new to this site and i must say i stumbled upon it and im pretty impressed with it, it looks fairly fandangle. anyway more to the point like the topic suggests whats the idea behind dual channel RAM and how does it make Hyper Threading more affective? Also Hypher Threading is not active unless you have both sticks of the same RAM in the slot right?
heaps of thanx me

Apparently from the answers in this thread:

Dual channel RAM requires 2 sticks. Not sure about the hyper-threading part of the question, though.

I'm mostly familiar with dual DDR for AMD platforms, however, I do know that some Intels run at 800mhz FSB (although its quad pumped)

since the fastest DDR module is 400mhz, only half the cpu to ram bridge is saturated

it you have two ram modules in dual ddr mode, each at 400mhz, you would saturate the bandwidth

yes you would that is why they sell DDR in bundles more often now.
Currently the fastest DDR is 566 more info on it here and for over all Ram info and bench marks go here they have a nice article on next gen DDR2 ram
