Upgrading the Memory

You can upgrade the system memory by adding single inline memory modules (SIMMs) into the SIMM sockets or by changing the SIMMs for a higher memory configuration.

The four 72-pin SIMM sockets support 4 MB and 16 MB single-density as well as 8 MB and 32 MB double- density SIMMs.

Table 2-2 lists the available memory configurations.

Bank 0		Bank 1		Total
Socket 0	Socket 1	Socket 0	Socket 1	Memory
4 MB	4 MB			8 MB
8 MB	8 MB			16 MB
16 MB	16 MB			32 MB
32 MB	32 MB			64 MB
32 MB	32 MB	32 MB	32 MB	128 MB

Consider the following when adding memory:

∙Always install SIMMs from the lowest bank first. For example, install SIMMs in bank 0 before bank 1.

∙Always remove SIMMs from the highest bank first. For example, bank 1 before bank 0.

∙Use only the same type of SIMM in a given bank.
