The system supports a minimum of 8 MB and a maximum of 128 MB of memory. Use only tin lead, 72-pin, 60 ns, Industry Standard EDO, non-parity SIMMs. Memory modules are installed in two memory banks, Bank 0 and Bank 1 (see "PC 340 Series (Type 6560) - Pentium 100/133/166 MHz System Board" on page 348). Each bank supports 4, 8, 16, or 32 MB single- or double-density SIMMs. Each bank used must contain a pair of SIMMs of the same size and density. For best performance, fill Bank 0 first. The following table shows some possible SIMM combinations and the total memory size for each combination: Bank 0 SIMM 1 SIMM 2 4 MB (single) 4 MB (single) 4 MB (single) 4 MB (single) 8 MB (double) 8 MB (double) 8 MB (double) 8 MB (double) 8 MB (double) 8 MB (double) Bank 1 SIMM 3 SIMM 4 − − 4 MB (single) − 4 MB (single) − 8 MB (double) 16 MB (single) 8 MB (double) 16 MB (single) Total 8 MB 16 MB 16 MB 32 MB 48 MB 254 IBM PC 300/700, IntelliStation Series HMM
