Windows 7: DDR2: dual or single channel?

DDR2: dual or single channel?

I'm upgrading the RAM on my P5Q Pro motherboard... Right now I have 3 GB total, 1 GB on slot 2 and 2GB on slot 4 running in dual channel mode.

Today I ordered a new 2GB stick. So I'll have 3 sticks of RAM on my motherboard, for a total of 5GB.

Considering that I will run 2+2GB in dual channel mode, if I add the third 1GB stick to the motherboard, will my RAM run in dual channel mode?

What is better in terms of performance? only 2+2GB or 2+2+1GB?

Those two 2GB sticks will run in dual channel if you install them in the correct slots, usually the same color. Adding the 1GB stick will not harm this.

Your motherboard manual should have the layout.

Best check the slots mate as I found my Asus P8Z77 the slots were not the closest to the CPU rather the furthest away which suprised me a bit. So looking at the board that would be the black slots.

Personally I would go (if you can afford it) 8GB and with a matched pair (kit) :)
