Memory Configurations
SIMMs install in pairs. You can install any SIMM memory
combination as long as you follow the basic requirement of in-
stalling identical modules in both sockets of a bank, i.e.:
• 5-Volt modules
• Both modules are the same size, e.g. 16MB (MegaBytes)
• Both are the same DRAM memory type, e.g. EDO
• Both use the same operating speed, e.g. 60ns (nanoseconds)
Each DIMM is a memory Bank. You can install DIMMs with
these specifications:
• 8MB to 128 MB single or double-sided modules
• 3.3-Volt unbuffered EDO or SDRAM DRAM modules only
Other than these requirements, there is no limitation on the
variety of possible combinations, so they are not listed here.
Memory Sockets
The picture at right shows the
memory module sockets.
Modules press into place and
are held in position by a re-
taining clamp at each end of
the socket.
When you want to remove a
module, press down on the
retaining clamps to push the
module out of the socket.
The SIMM sockets are num-
bered SIMM1 to SIMM4 as
noted. You must install mod-
ules in pairs in either sockets
1 & 2 or 3 & 4.
Modules snap into place and
are held in position by a re-
taining clip at each end of the
SIMM socket.
When you want to remove a
module, press down on the
retaining clips to release the
module from the socket.
