2-14 Chapter 2∞ Installing System MemoryThe mainboard provides four 168-pin DIMM sites for memory expansion.. TheDIMM socket supports 1Mx64(8MB), 2Mx64(16MB), 4Mx64(32MB),8Mx64(64MB),and16Mx64(128MB)or double sided DIMM modules. Minimummemory size is 8MB and maximum memory size is 512 MB SDRAM.There are four Memory module sockets on the system board.(Total eight banks)In order to create a memory array, certain rules must be followed. The followingset of rules allows for optimum configurations.l The memory array is 64 or 72 bits wide. (Without parity or with parity)l Support single and double density DIMMS.The following is the valid memory configuration:Bank Memory Module Total MemoryBank0.1(DIMM1)8MB,16MB, 32MB,64MB,128MB8MB ~ 128MBBank 2.3(DIMM2)8MB,16MB, 32MB,64MB,128MB8MB ~ 128MBBank 4.5(DIMM3)8MB,16MB,32MB,64MB, 128MB8MB ~ 128MBBank 6.7(DIMM4)8MB,16MB,32MB,64MB, 128MB8MB ~ 128MBTotal System Memory 8MB ~ 512MB* * * This table depicts the addressing requirements for each of therow/column organizations for each row size.
