System memory consists of up to four memory modules installed in sockets on the
system board (see Figure 8-5). The system uses registered synchronous dynamic ran-
dom-access memory (SDRAM) modules that provide error checking and correction
(ECC) capabilities.
By installing 128-, 256-, or 512-megabyte (MB) registered SDRAM memory modules,
you can increase system memory from its standard total of128 MB up to 2 gigabytes
(GB).

If the release lever on the microprocessor socket is not all the way up, move it to
that position now.
With the pin-1 corners of the chip and socket aligned, set the chip lightly in the
socket and make sure all pins are matched with the correct holes in the socket.
Because the system uses a ZIF microprocessor socket, there is no need to use
force (which could bend the pins if the chip is misaligned). When the chip is posi-
tioned correctly, it should drop down into the socket with minimal pressure.

A 3.0-V CR2032 coin-cell battery installed on the system board maintains system con-
figuration, date, and time information in a special section of memory.
8-16 Installation and Troubleshooting Guide
The operating life of the battery can extend up to 10 years. The battery may need
replacing if an incorrect time or date is displayed during the boot routine along with a
message such as:
Time-of-day not set - please run SETUP program
or
Invalid configuration information -
please run SETUP program
or
Strike the F1 key to continue,
F2 to run the setup utility
To determine whether the battery needs replacing, reenter the time and date through
the System Setup program and exit the program properly to save the information.
Turn off and unplug your system for a few hours, and then plug in and turn on your
system. Enter the System Setup program. If the date and time are not correct in the
System Setup program, replace your battery.
You can operate your system without a battery; however, without a battery, the sys-
tem configuration information maintained by the battery is erased if the system is
unplugged or AC power is lost. In this case, you must enter the System Setup pro-
gram and reset the configuration options.
