WARNING: To reduce the risk of personal injury when replacing or
!
removing RIMMs, allow the module being removed from the RIMM
slot sufficient time to cool before touching it. RIMM temperatures can
reach 100°C (212°F).
CAUTION: When handling a RIMM, do not touch any of the contacts.
Doing so may damage the module.
CAUTION: Static electricity can damage the electronic components
of the workstation or option boards. Before beginning these memory
upgrade procedures, ensure that you are discharged of static
electricity by briefly touching a grounded metal object.
Before installing additional RIMMs, read Guidelines for RIMM
Installation in this chapter.
Guidelines for RIMM Installation
When installing RIMMs, you must follow the guidelines listed below:
■ A RIMM can be installed only one way. Be sure to match the two
key slots 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. The
CRIMMs are removed when you populate the sockets with
RIMMs. For examples on the correct configuration sequence,
refer to the previous section, Configurations for RIMM
Installation.
■ 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 on the correct configuration sequence, refer to the
previous section, Configurations for RIMM Installation.
■ 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.
will reflect the lowest speed RIMMs.
Compaq Professional Workstation SP750 Hardware Reference Guide 2-9
Installing RIMMs
■ For proper system operation, the RIMMs must be industry-
standard, 168-pin, unbuffered RIMMs. The RIMMs must support
CAS Latency 2 or 3 (CL = 2 or CL = 3). They also must contain
the mandatory Joint Electronic Device Engineering Council
(JEDEC) Serial Presence Detect (SPD) information.
CAUTION: Static electricity can damage the electronic components
of the workstation or option boards. Before beginning these
procedures, ensure that you are discharged of static electricity by
briefly touching a grounded metal object.
CAUTION: The above guidelines must be followed when installing
RIMMs or your workstation will not function.
CAUTION: When handling a memory module, do not touch any of the
contacts. Doing so can damage the module.
WARNING: To reduce the risk of personal injury, when replacing or
!
removing RIMMs, allow the module being removed from the RIMM
slot sufficient time to cool before touching it. RIMM temperatures can
reach 100°C (212°F).
