When installing or replacing RIMMs, take the following information into
consideration:
v Any connector that does not have a RIMM installed must have a continuity
RIMM (C-RIMM), a module that looks like a RIMM but has no memory on it. A
C-RIMM is used to continue the connection on a RIMM connector that does not
have memory installed in it.
v Install only ECC RIMMs to enable ECC. If you use ECC and non-ECC memory
together, it will function as non-ECC memory.
v RIMM connectors do not support dual inline memory modules (DIMMs).
v Use only PC700 or PC800 RIMMs.
Note: If you use PC700 and PC800 RIMMs together, all memory will function at
the speed of the slowest RIMM.
To remove a C-RIMM or RIMM:
1. To locate the RIMM connectors inside your computer, see "Identifying parts on
the system board" on page 36.
2. At both ends of the RIMM connector on the system board, push outward on
the retaining clips until the module is loosened. Lift the RIMM or C-RIMM out
of the connector.
Note: Be careful not to push too hard on the retaining clips, because the RIMM
or C-RIMM might eject too quickly.
3. Store the RIMM or C-RIMM in a static-protective package. Do not discard or
lose this part. It might be needed later if you change your memory
configuration.
