Installing Additional Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2SDRAM) dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 8 GB of memory configured in a highperforming dual channel mode.
DDR2-SDRAM DIMMs
For proper system operation, the DDR2-SDRAM DIMMs must be:
industry-standard 240-pin
●
unbuffered PC2-5300 667 MHz-compliant or PC2-6400 800 MHz-compliant
●
1.8 volt DDR2-SDRAM DIMMs
●
The DDR2-SDRAM DIMMs must also:
support CAS latency 5 DDR2 667 Mhz (5-5-5 timing), CAS latency 5 DDR2 800 Mhz (5-5-5 timing),
●
and CAS latency 6 DDR2 800 Mhz (6-6-6 timing)
contain the mandatory JEDEC SPD information
●
In addition, the computer supports:
512Mbit and 1Gbit non-ECC memory technologies
●
single-sided and double-sided DIMMs
●
DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not
●
supported
NOTE: The system will not operate properly if you install unsupported DIMMs.
ENWW Installing Additional Memory 17
Populating DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A.
Sockets XMM3 and XMM4 operate in memory channel B.
Figure 2-9 DIMM Socket Locations
Table 2-1 DIMM Socket Locations
Item Description Socket Color
1 DIMM socket XMM1, Channel A
(populate first)
2 DIMM socket XMM2, Channel A White
3 DIMM socket XMM3, Channel B
(populate second)
4 DIMM socket XMM4, Channel B White
NOTE: A DIMM must occupy the XMM1 socket.
Black
Black
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
The system will operate in single channel mode if the DIMM sockets are populated in one channel
●
only.
The system will operate in a higher-performing dual channel mode if the total memory capacity of
●
the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B. The
technology and device width can vary between the channels. For example, if Channel A is
populated with two 512MB DIMMs and Channel B is populated with one 1GB DIMM, the system
will operate in dual channel mode.
The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not
●
equal to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel populated
with the least amount of memory describes the total amount of memory assigned to dual channel
18 Chapter 2 Hardware Upgrades ENWW
and the remainder is assigned to single channel. For optimal speed, the channels should be
balanced so that the largest amount of memory is spread between the two channels. If one channel
will have more memory than the other, the larger amount should be assigned to Channel A. For
example, if you are populating the sockets with one 1GB DIMM, and three 512MB DIMMs, Channel
A should be populated with the 1GB DIMM and one 512MB DIMM, and Channel B should be
populated with the two 512MB DIMMs. With this configuration, 2GB will run as dual channel and
512MB will run as single channel.
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
●
Installing DIMMs
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power to
drain before adding or removing memory modules. Regardless of the power-on state, voltage is always
supplied to the memory modules as long as the computer is plugged into an active AC outlet. Adding
or removing memory modules while voltage is present may cause irreparable damage to the memory
modules or system board. If you see an LED light on the system board, voltage is still present.
The memory module sockets have gold-plated metal contacts. When upgrading the 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.
Static electricity can damage the electronic components 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. For more information, refer to Appendix D,
on page 59.

2. Remove all removable media, such as diskettes or compact discs, from the computer.
3. Turn off the computer properly through the operating system, then turn off any external devices.
4. Disconnect the power cord from the power outlet and disconnect any external devices.
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the
power to drain before adding or removing memory modules. Regardless of the power-on state,
voltage is always supplied to the memory modules as long as the computer is plugged into an
active AC outlet. Adding or removing memory modules while voltage is present may cause
irreparable damage to the memory modules or system board. If you see an LED light on the system
board, voltage is still present.
5. If the computer is on a stand, remove the computer from the stand.
6. Remove the access panel.

Computer Operating Guidelines and Routine Care
Follow these guidelines to properly set up and care for the computer and monitor:
Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.
●
Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all vented
●
sides of the computer and above the monitor to permit the required airflow.
Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place the
●
keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also
restricts airflow.
Never operate the computer with the access panel or any of the expansion card slot covers
●
removed.
Do not stack computers on top of each other or place computers so near each other that they are
●
subject to each other’s re-circulated or preheated air.
If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must
●
be provided on the enclosure, and the same operating guidelines listed above will still apply.
Keep liquids away from the computer and keyboard.
●
Never cover the ventilation slots on the monitor with any type of material.
●
Install or enable power management functions of the operating system or other software, including
●
sleep states.
Turn off the computer before you do either of the following:
●
Wipe the exterior of the computer with a soft, damp cloth as needed. Using cleaning products
◦
may discolor or damage the finish.
Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other
◦
foreign matter can block the vents and limit the airflow.
ENWW Computer Operating Guidelines and Routine Care 61
Optical Drive Precautions
