T he f o ur DIMM sockets on th e sy ste m board can acc ommodate combina tions
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.
T here is no requiremen t 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 sock ets 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 el ectrically single-sided as they were in pre-
vious models, such as the Dell WorkStation 400 systems.
