Installation Guidelines
- The 4 SIMM sockets can accommodate from 16
to 128 MB of RAM.
- Supported SIMM sizes are 4, 8, 16, and 32
MB.
- SIMMs are 32- or 36-bit and 72-pin.
- SIMMs can be either fast-page mode or EDO:
- 16 meg of memory will be EDO nonparity
(standard EDO).
- 32 meg of memory will be EDO nonparity
or parity (customer's option).
- Above 32 meg of memory will be EDO
parity.
- Error correction code (ECC) only works if
the SIMMs are parity EDO memory.
- SIMMs must be installed in matched pairs
for connectors J3G1 and J3G2 and for J3H1 and J3H2.
- The number and arrangement of chips on the
SIMM may vary.
- The SIMMs used on this system have tin
leads.
