Memory

The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-SDRAM) dual inline memory modules (DIMMs).

DDR3-SDRAM DIMMs

The memory sockets on the system board can be populated with up to two 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 4 GB of memory configured in a high-performing dual channel mode.

For proper system operation, the DDR3-SDRAM DIMMs must be:

  • industry-standard 240-pin

  • unbuffered PC3-10600, 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:

  • 512Mbit, 1Gbit, and 2Gbit 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

The system will not operate properly if you install unsupported DIMMs.

Installing Memory Modules

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.

When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module.

  1. Prepare the computer for disassembly ( Preparation for Disassembly ).

  2. Remove the access panel ( Access Panel ).

  3. Locate the memory module sockets on the system board (500B shown).

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

Cable Management

Always follow good cable management practices when working inside the computer.

  • Keep cables away from major heat sources like the heatsink.

  • Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these are not designed to take excessive pressure on them.

  • Some flat ribbon cables come prefolded. Never change the folds on these cables.

  • Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.

  • Never crease a SATA data cable.

  • Do not rely on components like the drive cage, power supply, or computer cover to push cables down into the chassis. Always position the cables to lay properly by themselves.

When removing the power supply power cable from the connector on the system board, always follow these steps:

  1. Squeeze on the top of the retaining latch attached to the cable end of the connector (1).

  2. Grasp the cable end of the connector and pull it straight up (2).

    Always pull the connector - NEVER pull on the cable. Pulling on the cable could damage the cable and result in a failed power supply.
