Memory Module Installation

5-8 Upgrading the Compaq Deskpro EN Series, Minitower Model
The three memory sockets on the Intel 820 chipset–based
system board can be populated with industry-standard RIMMs.
These memory module slots are populated with preinstalled
RIMMs and/or continuity modules (CRIMMs). To achieve the
maximum memory support, you may be required to replace the
preinstalled RIMM and CRIMMs with higher capacity RIMMs.
All slots must be occupied by either memory modules (at least
one) or continuity modules.
For proper system operation, the RIMMs must be industry-
standard 184-pin, PC600–, PC700–, or PC800–compliant
RAMBUS memory modules, depending on the model. They
must also contain the mandatory Joint Electronic Device
Engineering Council (JEDEC) Serial Presence Detect (SPD)
information (1.0 or later). Intel 820 chipset–based Deskpro
models have one Direct RAMBUS channel that supports a
maximum of 32 devices. The total number of devices on all
RIMMs must be less than or equal to 32. Each RIMM includes
a label that lists the number of devices contained on the RIMM.
If you install RIMMs of varying speeds, the system will
run at the speed of the slowest installed RIMM.
RIMM upgrade kits are available as options from Compaq.
CAUTION:
Your memory module sockets have gold metal
contacts. When upgrading your memory, it is important to use
memory modules with gold metal contacts to prevent corrosion
and/or oxidation resulting from having incompatible metals in
contact with each other.
CAUTION:
Static electricity can damage the electronic com-
ponents of the computer or optional cards. Before beginning these
procedures, ensure that you are discharged of static electricity by
briefly touching a grounded metal object. Refer to Appendix F,
"Electrostatic Discharge," for more information.
CAUTION:
When handling a memory module, be careful not to
touch any of the contacts. Doing so may damage the module.
