Motherboard RAM Upgrade

[Myronazz]

Hello...

So recently, a friend asked me to upgrade his ram so first thing i check was if the motherboard supports more than 4 gigs of memory
It does not appear to support more than four, however im so paranoid that i made a mistake for some reason

Motherboard: ASUS P5SD2-VM
Can you please confirm the maximum amount of memory it supports?

Thanks in advance, your help is appreciated
