Installing Additional Memory

DIMMs

The computer comes with double data rate 3 synchronous dynamic random access memory (DDRS3-
SDRAM) dual inline memory modules (DIMMSs).

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 16-GB of memory configured in a high-
performing dual channel mode.

DDR3-SDRAM DIMMs

Ro,

ENWW

For proper system operation, the DDR3-SDRAM DIMMs must be:
e | industry-standard 240-pin

e | unbuffered non-ECC PC3-8500 DDR3-1066 MHz-compliant or PC3-10600 DDR3-1333 MHz-
compliant

&' NOTE: 1333 MHz DIMMS will only run at a speed of 1066 MHz.

o 1.5 volt DDR3-SDRAM DIMMs
The DDR3-SDRAM DIMMs must also:

e support CAS latency 7 DDR3 1066 MHz (7-7-7 timing) and CAS latency 9 DDR3 1333 MHz (9-9-9
timing)

e contain the mandatory JEDEC SPD information

In addition, the computer supports:

e | 512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies
e | single-sided and double-sided DIMMs

e DIMMSs 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 DIMMSs.

Installing Additional Memory 13

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 DIMMA. Sockets DIMM1 and DIMM2 operate in memory channel
A. Sockets DIMM3 and DIMMA4 operate in memory channel B.

Figure 2-7 DIMM Socket Locations

Table 2-1 DIMM Socket Locations

Item Description Socket Color
1 DIMM1 socket, Channel A (populate first) Black
2 DIMM2 socket, Channel A (populate third) White
3 DIMM3 socket, Channel B (populate second) White
4 DIMMA4 socket, Channel B (populate fourth) White

NOTE: A DIMM must occupy the black DIMM1 socket. Otherwise, the system will
display a POST error message indicating that a memory module must be installed in the
wrong socket.

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 DIMMSs in Channel A is equal to the total memory capacity of the DIMMSs in Channel B. The
technology and device width can vary between the channels. For example, if Channel A is
populated with two 512-MB DIMMs and Channel B is populated with one 1-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. Ifone channel

14 Chapter 2 Hardware Upgrades ENWW

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 1-GB DIMM, and three 512-MB DIMMSs,
Channel A should be populated with the 1-GB DIMM and one 512-MB DIMM, and Channel B should
be populated with the two 512-MB DIMMS. With this configuration, 2-GB will run as dual channel
and 512-MB will run as single channel.

e | Inany mode, the maximum operational speed is determined by the slowest DIMM in the system.

Installing DIMMs

À 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

on page 51.

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.
3. Tum offthe computer properly through the operating system, then tum off any external devices.
4

Disconnect the power cord from the power outlet and disconnect any external devices.

À 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. Ifyou see an LED light on the system
board, voltage is still present.

5. Remove the access panel.

/à WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.

D 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.

E 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.

lfthe 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:

o Wipe the exterior of the computer with a soft, damp cloth as needed. Using cleaning products
may discolor or damage the finish.

o 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.

52 Appendix E Computer Operating Guidelines, Routine Care and Shipping Preparation ENWW
