The four DIMM sockets on the system board can accommodate combinations
of 32-, 64-, and 128-MB DIMMs up to a total memory capacity of 512 MB
using unbuffered SDRAM, or it can accommodate combinations of 256-MB
registered SDRAM DIMMs up to 1024 MB using registered SDRAM DIMMs.
There is no requirement that one socket be filled before another, and
empty sockets can be left between installed DIMMs. However, Dell rec-
ommends populating the sockets in consecutive order starting with
DIMM A.
DIMM sockets do not have to contain DIMMs of the same size.
DIMMs of varying sizes may be installed in any order.
DIMMs are not required to be electrically single-sided as they were in pre-
vious models, such as the Dell WorkStation 400 systems.
