Memory Question

[Leodido]

I wanna add more RAM to my computer because at the moment I only have 2Gb(RAM Type in sig also mobo), I was wondering if I was better off buying 2Gb of this type of 4Gb of another type which would be better?

Thanks in advance!

Could I put 2Gb of this RAM instead of my old type ? TWIN2X2048-6400

It has the same spec on the Corsair website

CM2X1024-6400 PC2-6400 1GB 5-5-5-18 240pin DIMM

TWIN2X2048-6400 PC2-6400 2GB Kit 5-5-5-18 240pin DIMM
