Installing Main Memory Modules
Installing Main Memory Modules
• Each memory bank that you use must contain a pair of identical memory
modules, installed in the pair of sockets for that bank.
• The three memory banks (A, B, C) may be filled in any order, but it is advisable, for performance reasons, to fill them in the order A then B then C.
• Memory can be upgraded in increments of 8 MB, 16 MB, 32 MB or 64 MB
(by installing pairs of 4 MB, 8 MB, 16 MB or 32 MB modules).
• HP does not support PCs in which the user has installed non-HP
memory modules.
Initial Configuration Example Upgrade Paths
Models are supplied with 16 MB or 32 MB
of main memory using a pair of 8 MB or
16 MB, 60 ns, EDO memory modules.
The main memory capacity can be extended
to 144 MB or 160 MB by installing a further
two pairs of 32 MB memory modules.
This can be further extended to 192 MB by
removing the original pair of modules, and
replacing them with a pair of 32 MB
modules.

Banks may be filled in any order, but it is
recommended to fill them in the order of A
then B then C.
Any banks which are occupied must always
be filled with a pair of modules of
identical capacity, type and speed.
Different banks can be occupied by different
capacities of modules, such as a pair of
32 MB modules, a pair of 16 MB modules,
and a bank of 32 MB modules.
