Guidelines for RIMM Installation
Follow the guidelines listed below when installing RIMMs:
■
RIMMs must be installed correctly. Be sure to match the two key
sockets on the RIMM with the tabs on the RIMM socket. Push the
RIMM down into the RIMM socket, ensuring that it is fully
inserted and properly seated and that the retaining arms are locked
in place.
■
CRIMMs must be installed in all empty RIMM sockets. Remove
the CRIMMs when you want to populate the sockets with RIMMs.
For examples of the correct configuration sequence, see “Installing
RIMMs” in this chapter.
■
Install RIMMs in pairs across both memory channels. Each RIMM
socket populated with a RIMM or CRIMM on Channel A must be
populated with an identical RIMM or CRIMM on Channel B. For
examples of the correct configuration sequence, see “Installing
RIMMS” in this chapter.
■
Do not exceed 32-count Direct RDRAM devices on each Direct
Rambus memory channel. A label on the RIMM will indicate the
number and speed of Direct RDRAM devices on the RIMM.
✎
You cannot remove or add Direct RDRAMs to a RIMM
because the Direct RDRAMs are soldered on and encased by
another material.
■
Do not mix RIMMs with different memory speeds. Performance
will reflect the slowest speed RIMM.
CAUTION:
Static electricity can damage the electronic components
of the workstation or optional boards. Before beginning these
procedures, ensure that you are discharged of static electricity by
briefly touching a grounded metal object.
CAUTION:
Your workstation will not function if the above guidelines
are not followed when installing RIMMs.
CAUTION:
When handling a memory module, do not touch any of the
contacts. Doing so can damage the module.
