Main Memory
The four DIMM sockets on the system board can accommodate combinations of
•Any socket can be populated or not. There is no requirement that one socket be filled before the other, and empty sockets can be left between installed DIMMs. Dell recommends populating the sockets in order from A to D.
•Each DIMM socket does not have to contain DIMMs of the same size or speed. DIMMs may be installed in any order.
See “DIMMs” in Chapter 4 for information on removing and replacing DIMMs.
