Base/Board Memory
The XPS systems support four 32-bit (72-pin) SIMM sockets
(designated bank 0 through bank 3). The system supports from 4 to
64 MB of system RAM, using the following SIMM sizes:
- 4 MB, organized as 1 MB x 32 bits (nonparity)
- 16 MB, organized as 4 MB x 32 bits (nonparity)
The SIMMs are rated at 70 ns or better. The SIMM sockets have
tin-lead contacts, rather than the more expensive gold contacts.
At least one of the bank 0 through bank 3 sockets must be
populated for the system to operate. See Installing Memory for a table of
valid memory configurations.
Installing Memory
System RAM is upgradable to 64 MB by installing combinations
of 4- and 16-MB SIMMs.
