Hi again everyone,

I have a old tower sitting around not doing much there is a few posts concerning this computer already but this is a different one.

What I would like to do is increase the ram slightly from DDR2 6GB (2x2GB + 2x1GB)
to 8GB 4X2GB for use as a free nas box

I am useless with certain hardware parts and ram is one of them
Exactly what sort of ram would I need ?

I already no
it's DDR2
CPU-Z reports max bandwidth pc2-6400 (400mhz)
