    Dell Optiplex 755 + Maximum RAM?

    I have been donated an old Optiplex 755 to use as a server in the EG office (and to keep my hand in with Server 2008 R2 and it came with 2GB of PC4200 RAM. I obviously want to max it out, but dirrerant site such as Kinston and Crucial give differing amounts as to the maximum you can install. It varies from 2GB to 8GB!
    It is the SFF, not USFF chassis, so if anyone out there is using these and has an answer please let me know.

    Check the chipset, that will be the limiting factor. it is Q35, then the limit would be 8gb as per this document http://www.intel.com/assets/pdf/whitepaper/316971.pdf

    Assuming it has 4x DIMM slots, each DIMM having 2gb ....

    I have a 755 Q6600 mini-tower at home with 6gb installed, 2x 1gb + 2x 2gb DIMMs

    Having dug around a bit, I've found this ...

    Documentation

    So it's either 4GB for 32bit or 8GB for 64bit ..
