I have with me is my Acer revo 3700 and I want to upgrade my Acer revo 3700 that I just got a weeks ago. I looked all over the net to see which one works on it but hard luck I couldn’t find anything. I got a feedback from a person stating that it needs a 320 GB ram. Any confirmations on this? Because other reviews say that it has 256 GB ram. Any help would be great! Please help.
