I'm trying to buy new memory but I'm so confused.
Can you use 2 DDR2 single modules to make it DDR2 dual channel? If so, would I need to buy anything to do that? Why would you buy the Dual Channel Set over 2 single modules?
Like the guy said above, if your motherboard can do dual channel, you just get two modules of the same memory (exactly the same is best) and put them in the right slots for that, the motherboard manual will say how to do that.
And yes, if this is a new board, get one 1gb module and expand later, I'm running 512mb X 2 but my motherboard is 3 years old.
Best of luck.
