The following guidelines should be used when installing memory
Guidelines for
Installing modules:
•

•
Modules must be added in sets of eight, adding two modules
to each of the four MMBs.
Add modules starting at the empty MMB slots with the
lowest numbers. Add two modules to the corresponding
slots on each MMB, as shown by the shaded areas in
Figure 5–6.
Use the same size (MB) modules for a set of eight slots. For
example, you might add a set of eight 4-MB modules or a set
of eight 8-MB modules, but do not mix 4- and 8-MB modules
within a set. If you do mix different sizes of memory modules
within a set, your system will not recognize some of the
memory.
