III. INSTALLATION 2. System Memory (DRAM) This motherboard supports four 72-pin SIMMs of 4MB, 8MB, 16MB, or 32MB to form a memory size between 8MB to 128MB. For BUS frequencies of 50MHz or 60MHz, you can use either 60ns or 70ns modules. For BUS frequencies of 66MHz, you must use 60ns modules. Install memory in any or all of the banks in any combination as follows: Bank Bank 0 SIMM Slots 1&2 Memory Module 4MB, 8MB, 16MB, 32MB 72-pin FPM or EDO SIMM Total Memory x2 Bank 1 4MB, 8MB, 16MB, 32MB x2 SIMM Slots 3&4 72-pin FPM or EDO SIMM Total System Memory = IMPORTANT: Each bank must have the same size memory installed in pairs. IMPORTANT: Do not use memory modules with more than 24 chips per module. Modules with more than 24 chips exceed the design specifications of the memory subsystem and will cause unreliable operation. IMPORTANT: Do not use SIMM Modules that use an extra TTL chip to convert the memory module from asymmetric to symmetric. III. INSTALLATION (Memory) 12 P/I-P55TP4N User's Manual
