Adding System Memory and Upgrading the Internal Hard Drive

Adding System Memory
The memory sockets on the personal computer can be populated with
industry-standard DIMMs. These memory module slots are populated with at
least one preinstalled memory module. To achieve the maximum memory
support, you may be required to replace the preinstalled DIMM with a higher
capacity DIMM.
For proper system operation, the DIMMs must be industry-standard 168-pin,
100 MHz, unbuffered, PC100-compliant SDRAM DIMMs, or 133 MHz,
unbuffered, PC133-compliant SDRAM DIMMs. If two DIMMs are installed,
they must be the same speed. This computer comes equipped with 133 MHz
DIMMs.
The SDRAM DIMMs must support CAS Latency 2 or 3 (CL = 2 or CL = 3).
They must also contain the mandatory Joint Electronic Device Engineering
Council (JEDEC) Serial Presence Detect (SPD) information. DIMMs
constructed with x4 SDRAM are not supported; the system will not start when
equipped with unsupported DIMMs.
Adding or Removing a Memory Module
Ä
CAUTION: Your memory module sockets have gold-plated metal contacts. When upgrading your
memory, it is important to use memory modules with gold-plated metal contacts to prevent
corrosion and/or oxidation resulting from having incompatible metals in contact with each other.
Ä
CAUTION: Static electricity can damage the electronic components of the Personal Computer.
Before beginning these procedures, ensure that you are discharged of static electricity by briefly
touching a grounded metal object. Refer to “Electrostatic Discharge” in the Troubleshooting
Guide for more information.
Ä
CAUTION: When handling a memory module, be careful not to touch any of the contacts. Doing
so may damage the module.
1. Exit all software applications, shut down the operating system software,
turn off the Personal Computer and any external devices, then disconnect
the power cord from the power outlet.
2. Remove the right access panel. Refer to “Removing and Replacing the
Side Access Panels” on page 3-2.
