Installing Additional
Memory
You can expand computer memory by installing industry
standard, 168-pin synchronous DRAM dual inline memory
modules (DIMMs). For proper system operation, use 66MHz or
faster unbuffered DIMMs. DIMM upgrade kits are available as
options from Compaq.
The system board includes three memory module slots.
However, one or more of these memory module slots is used to
hold the standard 16- or 32-megabyte memory module(s). You
must replace the preinstalled memory module with a 128-
megabyte memory module to achieve maximum memory of 384
megabytes.
CAUTION:
Your DIMM sockets have gold metal contacts that are
silver in appearance. When upgrading your memory, it is important
to use DIMMs with gold metal contacts (not tin-lead) 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 boards. Before beginning
these procedures, ensure that you are discharged of static
electricity by briefly touching a grounded metal object. Refer to
Appendix F for more information.
CAUTION:
When handling a memory module, be careful not to
touch any of the contacts. Doing so may damage the module.
Installing DIMM Modules
To install a memory module, complete the following steps:
1. If you have locked the Smart Cover Lock, use Computer
Setup to unlock the lock.
For more information about Computer Setup, refer to
Chapter 8, “Using Compaq Utilities.”
2. Turn off the computer, disconnect the power cord from the
electrical outlet, and remove the computer cover.
3. Remove the expansion board cage and locate the DIMM
sockets.
