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 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 32-GB of memory configured in a
high-performing 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

●

1.35 volt or 1.5 volt DDR3/DDR3L-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.

Populating DIMM sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory
channel B. Sockets DIMM3 and DIMM4 operate in memory channel A.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.

18

Chapter 2 Tower (TWR) hardware upgrades

ENWW

NOTE: Single channel and unbalanced dual channel memory configurations will result in inferior
graphics performance.
●

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 1-GB DIMMs and Channel B is populated with one 2-GB 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.
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 2-GB DIMM, and three 1-GB
DIMMs, Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel
B should be populated with the other two 1-GB DIMMs. With this configuration, 4-GB will run as
dual channel and 1-GB 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.
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 Electrostatic discharge on page 100.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.

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 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 32-GB of memory configured in a
high-performing 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

●

1.35 volt or 1.5 volt DDR3/DDR3L-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.

Populating DIMM sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory
channel B. Sockets DIMM3 and DIMM4 operate in memory channel A.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.

ENWW

Installing additional memory

61

NOTE: Single channel and unbalanced dual channel memory configurations will result in inferior
graphics performance.
●

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 1-GB DIMMs and Channel B is populated with one 2-GB 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.
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 2-GB DIMM, and three 1-GB
DIMMs, Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel
B should be populated with the other two 1-GB DIMMs. With this configuration, 4-GB will run as
dual channel and 1-GB 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.
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 Electrostatic discharge on page 100.
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 compact discs or USB flash drives, from the computer.

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.

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:

ENWW

●

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.

Computer operating guidelines and routine care 101

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.

●

Avoid exposing the drive to sudden changes in temperature, as condensation may form inside
the unit. If the temperature suddenly changes while the drive is on, wait at least one hour before
you turn off the power. If you operate the unit immediately, it may malfunction while reading.

●

Avoid placing the drive in a location that is subject to high humidity, extreme temperatures,
mechanical vibration, or direct sunlight.

Cleaning
●

Clean the panel and controls with a soft, dry cloth or a soft cloth lightly moistened with a mild
detergent solution. Never spray cleaning fluids directly on the unit.

●

Avoid using any type of solvent, such as alcohol or benzene, which may damage the finish.

Safety
If any object or liquid falls into the drive, immediately unplug the computer and have it checked by an
authorized HP service provider.

Shipping preparation
Follow these suggestions when preparing to ship the computer:
1.

Back up the hard drive files on PD discs, tape cartridges, CDs, or USB flash drives. Be sure that
the backup media is not exposed to electrical or magnetic impulses while stored or in transit.
NOTE: The hard drive locks automatically when the system power is turned off.

2.

Remove and store all removable media.

3.

Turn off the computer and external devices.

4.

Disconnect the power cord from the electrical outlet, then from the computer.
