http://serverfault.com – I am basically away from my office, but would like to check whether a pc (which has 4GB of RAM) has 4x 1GB DIMMs or 2x 2GB DIMMs. I am referring to a windows XP system. Is it possible to gather this info from System information or otherwise, remotely? Thank you for your help (HowTos)
