Installing Additional Memory
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3SDRAM) dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to two 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.
DDR3-SDRAM DIMMs
For proper system operation, the DDR3-SDRAM DIMMs must be:
● industry-standard 240-pin
unbuffered non-ECC PC3-12800 DDR3-1600 MHz-compliant
●
1.5 volt DDR3-SDRAM DIMMs
●
The DDR3-SDRAM DIMMs must also:
support CAS latency 11 DDR3 1600 MHz (11-11-11 timing)
●
contain the mandatory JEDEC SPD information
●
In addition, the computer supports:
512-Mbit, 1-Gbit, and 2-Gbit 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.
16 Chapter 2 Hardware Upgrades
Populating DIMM Sockets
There are two DIMM sockets on the system board: XMM1 and XMM3 with one socket per Channel.
XMM3 operates in memory channel A. XMM1 operates in memory Channel B.
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 DIMM in Channel A is equal to the total memory capacity of the DIMM in Channel B.
The system will operate in flex mode if the total memory capacity of the DIMM in Channel A is
●
not equal to the total memory capacity of the DIMM 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. If one channel will have more
memory than the other, the larger amount should be assigned to Channel A.
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.
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
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.

C Electrostatic Discharge
A discharge of static electricity from a finger or other conductor may damage system boards or other
static-sensitive devices. This type of damage may reduce the life expectancy of the device.
Preventing Electrostatic Damage
To prevent electrostatic damage, observe the following precautions:
Avoid hand contact by transporting and storing products in static-safe containers.
●
Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
●
Place parts on a grounded surface before removing them from their containers.
●
Avoid touching pins, leads, or circuitry.
●
Always be properly grounded when touching a static-sensitive component or assembly.
●
Grounding Methods
There are several methods for grounding. Use one or more of the following methods when handling
or installing electrostatic-sensitive parts:
Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis.
●
Wrist straps are flexible straps with a minimum of 1 megohm +/- 10 percent resistance in the
ground cords. To provide proper ground, wear the strap snug against the skin.
Use heelstraps, toestraps, or bootstraps at standing workstations. Wear the straps on both feet
●
when standing on conductive floors or dissipating floor mats.
Use conductive field service tools.
●
Use a portable field service kit with a folding static-dissipating work mat.
●
If you do not have any of the suggested equipment for proper grounding, contact an HP authorized
dealer, reseller, or service provider.
NOTE: For more information on static electricity, contact an HP authorized dealer, reseller, or
service provider.

D Computer Operating Guidelines,
Routine Care and Shipping Preparation
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.
54 Appendix D Computer Operating Guidelines, Routine Care and Shipping Preparation
Optical Drive Precautions
Be sure to observe the following guidelines while operating or cleaning the optical drive.
Operation
Do not move the drive during operation. This may cause it to malfunction during reading.
