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 up to 2048 MB using registered SDRAM DIMMs.
A minimum of 64 MB RAM is required.

There is no requirement that one socket be filled before the other, and empty
sockets can be left between installed DIMMs. However, Dell recommends
populating the sockets in consecutive order starting with DIMM A. DIMM
sockets do not have to contain DIMMs of the same size. DIMMs may be
installed in any order.
See “DIMMs” in Chapter 4 for information on removing and replacing DIMMs.
