I just replaced two of an HP 715's eight 16Mb modules with two 64Mb modules from an old machine. This should have given me 224Mb ((128 - 32) + 128) but it only shows 160Mb on boot.<br><br>What's worse, the top command shows only 64MB - (top output) Memory: 4608K (1928K) real, 11468K (7760K) virtual, 57584K free<br><br>Is there something else I need to do to get the system to see new RAM?
