Installing Additional Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2-
SDRAM) 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 4 GB of memory configured in a high-
performing 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
●1.8 volt DDR2-SDRAM DIMMs
The DDR2-SDRAM DIMMs must also:
●support CAS latency 4 and 5 for DDR2/667 MHz
●contain the mandatory JEDEC SPD information
In addition, the computer supports:
●256Mbit, 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 start if you install unsupported DIMMs.
12 Chapter 2 Hardware Upgrades ENWW

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 2-5 DIMM Socket Locations
Item Description Socket Color
1DIMM socket XMM1, Channel A
(populate first)
Black
2DIMM socket XMM2, Channel A White
3DIMM socket XMM3, Channel B
(populate second)
Black
4 DIMM socket XMM4, Channel B White
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 256MB DIMMs and Channel B is populated with one 512MB 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
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. For example,
if you are populating the sockets with one 1GB DIMM, two 512MB DIMMs, and one 256MB DIMM,
ENWW Installing Additional Memory 13

one channel should be populated with the 1GB DIMM and one 256MB DIMM and the other channel
should be populated with the two 512MB DIMMs. With this configuration, 2 GB will run as dual
channel and 256 MB 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, Electrostatic Discharge.
When handling a memory module, be careful not to touch any of the contacts. Doing so may
damage the module.
1. Remove/disengage any security devices that prohibit opening the computer.
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. Remove the computer access panel.
6. Locate the memory module sockets on the system board.
WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.
