Installing the Mainboard
Scenario 1: You use only 72-pin SIMM modules:
l The maximum memory size is 128M bytes.
l Support possible for single density or double density memory
modules.
l Memory modules supported: 1Mx32¡i 4M¡j , 2Mx32
¡i 8M¡j , 4Mx32¡i 16M¡j or 8Mx32¡i 32M¡j .
l ¡i SIMM1 and SIMM2¡j is the first pair, ¡i SIMM3 and
l You can also directly refer to table 2-1.
Scenario 2: You use only 168-pin DIMM modules:
l The maximum memory size is:
l Support possible for single density or double density memory
modules.
l Memory modules supported: 1Mx64¡i 8M¡j , 2Mx64
¡i 16M¡j or 4Mx64¡i 32M¡j .
l DIMM1 is the first pair, DIMM2 is the second pair. Usually,
you first insert modules in DIMM1 socket, than in DIMM2
socket, but it is possible to do the reverse.
l You can also directly refer to table 2-2.
Scenario 3: You use 72-pin SIMM modules and 168-pin DIMM modules:
l The maximum memory size is:
l Support possible for single density or double density memory
l Memory modules supported: Refer to case 1 and case 2
l Support possible for mixed use of single density and double
l Since there is a lot of possible configurations, no table is given.
SIMM4¡j is the second pair. Usually, you first insert the first
pair, than the second pair, but it is possible to do the reverse.
