How to Install Memory

The motherboard has four 72-pin, tin-lead SIMM
sockets that support from 8 MB to 256 MB of
memory. The sockets are arranged as banks
0 and 1 (Figure 11). Two sockets make up one
bank.
When adding memory, follow these guidelines:
•
When adding SIMMs, use only tin-lead,
72-pin, 50 or 60 ns EDO DRAM. Faster
devices will not improve system
performance.
•
When you install SIMMs, you must
completely fill at least one bank; that is, you
must install SIMMs in both sockets of the
bank.
•
The computer automatically detects the
installed memory, so it doesn't matter which
bank is used, as long as both sockets in the
bank are filled. Because of limited space on
the motherboard, it might be easier to install
SIMMs in bank 0 first.

•
Both SIMMs in one bank must be the same
size. For example, don't install a 4 MB SIMM
in one socket of bank 0 and an 8 MB SIMM
in the second socket of bank 0. You may,
however, use different size SIMMs in
different banks.
NOTE
The motherboard supports parity (x36) or
non-parity (x32) SIMMs. Error checking
and correction is supported with parity and
ECC SIMMs. There is no error checking
and correction with non-parity SIMMs.
