Guidelines for RIMM Installation
When installing RIMMs, you must follow these guidelines:
■ RIMMs must be installed correctly. Be sure to match the two
on the RIMM with the tabs on the RIMM socket. Push the
slots
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. The
CRIMMs are removed when you populate the sockets with
RIMMs. For examples of the correct configuration sequence, refer
to the section, Installing RIMMs.
■ 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, refer to the
section, "Installing RIMMs.
■ Do not exceed 32-count Direct RDRAM devices on each Direct
Rambus memory channel. A label on the RIMM will indicate the
number of Direct RDRAM devices on the RIMM and their speed.
✎
■ Do not mix RIMMs with different memory speeds. Performance
You cannot remove or add Direct RDRAMS to a RIMM
because the Direct RDRAMS are soldered on and encased by
another material.
