Hello, I'm looking to upgrade the ram on my aurora r2. It has at the moment 2x1gb (TW149) single sided and 2x2gb (P223C) double sided Samsung ram cards. I'm wanting to max out at 4x4gb. Having trouble finding specific ram that would work. I have a dell( CN-0RV30W) M.B with a Intel i3 530 2.93GHz processor. If anyone can assist, please help. Thank you.
