i have a dfi 250gb nf3 mobo and was wondering if it supports dual channel? in this review here it doesn't mention dual channel and in cpuz it says in "channel #" single

socket 754 processors operate on single channel

socket 939 processors operate on single (if only 1 memory stick) or dual channel
