Installing Additional Memory
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-
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 16-GB of memory configured in a
high-performing dual channel mode.
DDR3-SDRAM DIMMs
CAUTION: This product DOES NOT support DDR3 Ultra Low Voltage (DDR3U) memory. The
processor is not compatible with DDR3U memory and if you plug DDR3U memory into the system
board, it can cause the physical damage to the DIMM or invoke system malfunction.
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.
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.
Installing Additional Memory 17
Page: 25
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 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 92.
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. 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.

5. Remove the computer access panel.
WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.
6. Open both latches of the memory module socket (1), and insert the memory module into the
socket (2).
Figure 2-8 Installing a DIMM
NOTE: A memory module can be installed in only one way. Match the notch on the module
with the tab on the memory socket.
Populate the black DIMM sockets before the white DIMM sockets.
For maximum performance, populate the sockets so that the memory capacity is spread as
equally as possible between Channel A and Channel B. Refer to Populating DIMM Sockets
on page 17 for more information.
7. Push the module down into the socket, ensuring that the module is fully inserted and properly
seated. Make sure the latches are in the closed position (3).
8. Repeat steps 6 and 7 to install any additional modules.
9. Replace the computer access panel.
10. Reconnect the power cord and turn on the computer.
11. Lock any security devices that were disengaged when the access panel was removed.

connector on the system board labeled SATA0. If you are adding a second hard drive, connect it
to the white connector on the system board labeled SATA1.
● Connect the first SATA optical drive to the white SATA connector on the system board labeled
SATA2. If you are adding a second optical drive connect it to the black SATA connector on the
system board labeled ESATA. If the ESATA connector is already populated, connect the second
optical drive to the white connector labeled SATA1.
● Connect an optional eSATA adapter cable to the black SATA connector on the system board
labeled ESATA.
● Connect a media card reader USB cable to the USB connector on the system board labeled
MEDIA.
● The power cable for the SATA optical drives is a two-headed cable this is plugged into the
system board with the first connector routed to the top 5.25-inch bay and the second connector
routed to the bottom 5.25-inch bay.
● The power cable for the SATA hard drives is a two-headed cable this is plugged into the system
board with the first connector routed to the bottom 3.5-inch bay and the second connector routed
to the top 3.5-inch bay.
● The system does not support Parallel ATA (PATA) optical drives or PATA hard drives.
● You must install guide screws to ensure the drive will line up correctly in the drive cage and lock
in place. HP has provided extra guide screws for the drive bays (four 6-32 isolation mounting
guide screws and eight M3 metric guide screws), installed on the side of the drive bays. The
6-32 isolation mounting screws are required for a secondary hard drive. All other drives (except
the primary hard drive) use M3 metric screws. The HP-supplied metric screws are black and the
