Memoreeeeee

Hey guys here at technology, i'm a psychic, but I am not computer literate. I have only 512mb Ram on this comp, and I have a Asus P5GD1-VM motherboard, and i've asked people about what kind of ram I could get, yet noone gives me the same answer, so I turn to you, the internet.

tl;dr
I have an Asus P5GD1-vm. I do not know what kind of ram I can get. Could you tell me what would work in this mobo? Thanks.

If you help me I predict a happy future for you.

Assuming someone installed it for you, did you ever think to look your existing RAM to see what will work?

says "Dual-Channel DDR 400" so avoid the older single-channel DDR spec as the two are incompatible with one another.

So look for: PC2-3200 / DDR2-400 chips,
anything faster should be able to downclock:
PC2-4200 / DDR2-533 chips
PC2-5300 / DDR2-667 chips
PC2-6400 / DDR2-800 chips
