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 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.

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.

ENWW Installing additional memory 19

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).

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 18 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.

The computer should automatically recognize the additional memory the next time you turn on the

computer.

20 Chapter 2 Tower (TWR) hardware upgrades ENWW
