A memory upgrade/installation can fail for several
reasons:

1) In a two-memory-board installation, a single-

sided memory card has been installed into slot 1
that does not have a PD jumper.

2) A memory board is not seated properly when

installed.

3) Memory is installed correctly but is of insufficient

size.

4) One or both of the memory boards has failed.

Check the following tables for the symptom you are
experiencing to identify a course of action.

The Diagnostic Test
Page indicates that the
controller is
recognizing memory,
but it is not of the
expected size.

1) The SIMM installed in

slot 1 is not a double-
sided memory card.

Procure a SIMM that is double-
sided and install into slot 1.

2) The SIMM installed in

slot 2 is not seated
properly

Properly re-install the SIMM in
slot 2.

3) The installed SIMM(s)

has (have) a memory
size that is actually
smaller than it’s
specification.

a) Check to make sure the board

part numbers are correct for
the SIMM size.  If not, obtain
and install the correct ones
for the desired memory size.

b) The SIMM could have a fault

in which it only reports part
(for example, one-half) of the
memory for which it is rated.
In this case, the board must
be returned to the vendor for
replacement.
