Hi I have 3gb and it works just fine, would have put 4gb but would have meant I was left with a 1 gb board

Hi, I bouught 1x 2Gb chip and 1x 1 Gb, seems to work fine.

Hi, I thought I would add this. Have installed 3gb of ram on the 5535 but still had high CPU usage and slow operation. I was using Zone Alarm (now removed) and from the advice of my dealer installed AVG free. It has made an incredible difference in performance and the CPU is now down at 10-15%.

The specs for the M672 say that it has TV out, does anyone know how to activate this through the VGA port?
