Hi everyone,

Everyone here knows how hard it is to choose the best performance/$ components. But apart from all the other problems i had this question.

I decided to buy myself 4GB of ram. But the problem for me is which one of the choices below grants more performance.
I will assume that all of the RAM choices have equal MHZ values, and same brand

a. 4* 1GB of ram
b. 2* 2GB of ram
c. 1* 4GB of ram

Considering FSB there shouldnt be any increase between CPU and memory path, but i ve been told about this and i wonder if it is true?

Any ideas?

2 x 2GB - to take advantage of Dual Channel operation

1x4GB - No Dual Channel (around a 5% loss in performance)

4 x 1 GB - Electrically, this is harder for your motherboard to drive.

I would go with 2x2GB and leave room for more later, and to take advantage of dual-channel, and to minimize the strain on your board while taking all the advantages.

isnt dual channel works in a single ram? I mean if you go to kingston's


it says "DUAL CHANNEL MEMORY KITS". I thought dual channel technology thingy happens in a single slot Memory? am i wrong ?
Or do i have to buy 2 slots of 2GB memory for dual channel to work ?

The stick itself may be Dual Channel capable - But you *must* run them in pairs for Dual channel operation.
