We have an Optiplex 760 with three 2G sticks installed.
RAMMon reports three sticks @ 2G each, slots 1,2,3.
But then it reports total physical RAM as only 3058G
and then it reports usable RAM as only 1326MB !
The RAM is DDR2 400 clock speed, PC2-6400 Bandwidth, DDR2-800 Transfer speed according to RAMMon.
Two sticks made by Nanya and one by Hynix.
It would be nice if I could get all 6G working.
Anyone have any suggestions I wonder? Pretty old machine but maybe someone.....
Sounds like you're running a 32-bit operating system - to use more than 4G you'll need to load a 64-bit OS.
