2-16 Chapter 2
After installing the DRAM, the BIOS of the mainboard will automatically detect
the size of the memory installed on the mainboard. Below is a list of all the possible
situations:
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【4M】, 2Mx32【8M】,
4Mx32【16M】or 8Mx32【32M】.
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 128M bytes.
l Support possible for single density or double density memory
modules.
l Memory modules supported: 1Mx64【8M】, 2Mx64
【16M】or 4Mx64【32M】.
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: 256M bytes.
l Support possible for single density or double density memory
modules.
l Memory modules supported: Refer to case 1 and case 2 above.
l Support possible for mixed use of single density and double density
modules.
l Since there is a lot of possible configurations, no table is given.
