Tip: The SIMM/DIMM chip count can be calculated by
following example:
1. For 32 bit non-parity SIMM using 1M by 4 bit DRAM
chip, 32/4=8 chips.
2. For 36 bit parity SIMM using 1M by 4 bit DRAM
chip, 36/4=9 chips.
3. For 36 bit parity SIMM using 1M by 4 bit and 1M by
1 bit DRAM, the chip count will be 8 data chips(8=
32/4) plus 4 parity chips(4=4/1), total is 12 chips.
4. For 64 bit DIMM using 1M by 16 bit SDRAM, the
chip count is 64/16=4 chips.
Following table list the recommended DRAM combinations of SIMM and
DIMM:
