3 Serial ATA (SATA) Drive Guidelines
and Features
NOTE: HP only supports the use of SATA hard drives on these models of computer. No Parallel ATA
(PATA) drives are supported.
SATA Hard Drives
Serial ATA Hard Drive Characteristics
Number of pins/conductors in data cable 7/7
Number of pins in power cable 15
Maximum data cable length 39.37 in (100 cm)
Data interface voltage differential 400-700 mV
Drive voltages 3.3 V, 5 V, 12 V
Jumpers for configuring drive N/A
Data transfer rate 3.0 Gb/s
SATA Hard Drive Cables
SATA Data Cable
Always use an HP approved SATA 3.0 Gb/s cable as it is fully backwards compatible with the SATA
1.5 Gb/s drives.
Current HP desktop products ship with SATA 3.0 Gb/s hard drives.
SATA data cables are susceptible to damage if overflexed. Never crease a SATA data cable and never
bend it tighter than a 30 mm (1.18 in) radius.
The SATA data cable is a thin, 7-pin cable designed to transmit data for only a single drive.
30 Chapter 3 Serial ATA (SATA) Drive Guidelines and Features
SMART ATA Drives
The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal
Computers have built-in drive failure prediction that warns the user or network administrator of an
impending failure or crash of the hard drive. The SMART drive tracks fault prediction and failure
indication parameters such as reallocated sector count, spin retry count, and calibration retry count. If
the drive determines that a failure is imminent, it generates a fault alert.
Hard Drive Capacities
The combination of the file system and the operating system used in the computer determines the
maximum usable size of a drive partition. A drive partition is the largest segment of a drive that may be
properly accessed by the operating system. A single hard drive may therefore be subdivided into a
number of unique drive partitions in order to make use of all of its space.
Because of the differences in the way that drive sizes are calculated, the size reported by the operating
system may differ from that marked on the hard drive or listed in the computer specification. Drive size
calculations by drive manufacturers are bytes to the base 10 while calculations by Microsoft are bytes
to the base 2.

Care, and Disassembly Preparation
This chapter provides general service information for the computer. Adherence to the procedures and
precautions described in this chapter is essential for proper service.
CAUTION: When the computer is plugged into an AC power source, voltage is always applied to
the system board. You must disconnect the power cord from the power source before opening the
computer to prevent system board or component damage.

Electrostatic Discharge Information
A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive
devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic
device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work
perfectly throughout a normal cycle. The device may function normally for a while, but it has been
degraded in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge
contains enough power to alter device parameters or melt silicon junctions.
Generating Static
The following table shows that:
Different activities generate different amounts of static electricity.
●
Static electricity increases as humidity decreases.
●
Event 55% 40% 10%

Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree
of sensitivity. The following packaging and grounding precautions are necessary to prevent damage to
electric components and accessories.
To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.
●
Protect all electrostatic parts and assemblies with conductive or approved containers or
●
packaging.
Keep electrostatic sensitive parts in their containers until they arrive at static-free stations.
●
Electrostatic Discharge Information
35
Place items on a grounded surface before removing them from their container.
●
Always be properly grounded when touching a sensitive component or assembly.
●
Avoid contact with pins, leads, or circuitry.
●
Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive
●
foam.
Personal Grounding Methods and Equipment
Use the following equipment to prevent static electricity damage to equipment:
●
Wrist straps are flexible straps with a maximum of one-megohm ± 10% resistance in the ground
cords. To provide proper ground, a strap must be worn snug against bare skin. The ground cord
must be connected and fit snugly into the banana plug connector on the grounding mat or
workstation.
●
Heel straps/Toe straps/Boot straps can be used at standing workstations and are
compatible with most types of shoes or boots. On conductive floors or dissipative floor mats, use
them on both feet with a maximum of one-megohm ± 10% resistance between the operator and
ground.

Antistatic plastic
Carbon-loaded plastic
Metallized laminate
Grounding the Work Area
To prevent static damage at the work area, use the following precautions:
Cover the work surface with approved static-dissipative material. Provide a wrist strap connected
●
to the work surface and properly grounded tools and equipment.
Use static-dissipative mats, foot straps, or air ionizers to give added protection.
●
Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate.
●
Handle them only at static-free work areas.
Turn off power and input signals before inserting and removing connectors or test equipment.
●
Use fixtures made of static-safe materials when fixtures must directly contact dissipative surfaces.
●
Keep work area free of nonconductive materials such as ordinary plastic assembly aids and
●
Styrofoam.

Operating Guidelines
To prevent overheating and to help prolong the life of the computer:
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.
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. Be sure to unplug the computer before cleaning
the air vents.
Never operate the computer with the cover or side panel 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.
Operating Guidelines
37
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.

drives only.
CAUTION: As each subassembly is removed from the computer, it should be placed away from the
work area to prevent damage.
Cables and Connectors
Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care
to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or
removal from the connector. Handle cables by the connector whenever possible. In all cases, avoid
bending or twisting the cables, and ensure that the cables are routed in such a way that they cannot be
caught or snagged by parts being removed or replaced.
CAUTION: When servicing this computer, ensure that cables are placed in their proper location
during the reassembly process. Improper cable placement can damage the computer.
Hard Drives
Handle hard drives as delicate, precision components, avoiding all physical shock and vibration. This
applies to failed drives as well as replacement spares.
If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective
●
packaging and label the package “Fragile: Handle With Care.”
Do not remove hard drives from the shipping package for storage. Keep hard drives in their
●
protective packaging until they are actually mounted in the CPU.
Avoid dropping drives from any height onto any surface.

Memory
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3SDRAM) dual inline memory modules (DIMMs).
DDR3-SDRAM 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 either 8 GB or 16 GB of memory
configured in a high-performing dual channel mode, depending on model.
Model Number Maximum Memory
HP Pro 3120 8 GB
HP Pro 3125 16 GB
HP Pro 3130 16 GB
Bezel Blanks
45
For proper system operation, the DDR3-SDRAM DIMMs must be:
industry-standard 240-pin
●
unbuffered non-ECC PC3-10600 DDR3-1333 MHz-compliant
●
1.5 volt DDR3-SDRAM DIMMs
●
The DDR3-SDRAM DIMMs must also:
support CAS latency 9 DDR3 1333 MHz (9-9-9 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.
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 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 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.
