3-14 OptionsSIMM Memory InstallationThe system board comes standard with 8 MB of 32-bit (non-parity) memory for non-multimediaconfigurations and 16 MB of 32-bit memory for multimedia configurations. Memory can be ex-panded up to 128 MB. The system board also supports 36-bit (parity) SIMMs. SIMM kits are70-ns SIMMs.NOTE: The metal plating on the SIMM stick con-nectors must match the metal plating in the SIMMsockets in the computer. Use tin-plated SIMMsticks with tin-plated SIMM sockets.Memory expansion option kits include the following:n 4-MB SIMM kit (1 MB x 32-bit SIMM stick).n 8-MB SIMM kit (2 MB x 32-bit SIMM stick).n 16-MB SIMM kit (4 MB x 32-bit SIMM stick).n 32-MB SIMM kit (8 MB x 32-bit SIMM stick).n 64-MB SIMM kit (16 MB x 32-bit SIMM stick).NOTE: The 32-bit SIMM kits are used in theU.S. and Canada only. The 36-bit SIMMs are usedelsewhere.SIMM Upgrade PathThe SIMMs come in two different types, single-sided or double-sided. In the 8-MB non-multimedia configurations, two 4-MB single-sided SIMMs are installed in SIMM sockets 1 and 2(bank 0). In the 16-MB multimedia configurations, two 8-MB double-sided SIMMs are installedin SIMM sockets 1 and 2. Figure Section 3-12 shows the location of the sockets and banks.Table Section 3-3 and Table Section 3-4 provide valid SIMM configurations.Setting the system for use with single-sided or double-sided SIMMs is done by jumper JP1 onthe system board, next to the SIMM sockets. For systems with the 8-MB configuration, pins 2and 3 on JP1 are shorted. Also, pins 2 and 3 must be shorted if installing the following SIMMs insockets 1 and 2 (bank 0):n 1 MB SIMMsn 4 MB SIMMsn 16 MB SIMMs
