  • Page 37: Memory

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

  • Page 38: Populating Dimm Sockets

    Populating DIMM Sockets There are four DIMM sockets on the system board, with two sockets per channel. Populate the DIMM sockets in the following order: DIMM1 then DIMM2 Figure 6-4 DIMM Socket Locations Table 6-1 DIMM Socket Locations Item Description Socket Color Insertion Order DIMM1 socket, Channel A...

  • Page 39: Installing Memory Modules

    ● 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.
  • Page 40 Open both latches of the memory module socket (1), and insert the memory module into the socket (2). Figure 6-5 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.

  • Page 42 On the rear of the computer, a slot cover lock secures the expansion card brackets in place. Remove the screw from the slot cover lock then slide the slot cover lock up to remove it from the chassis. Figure 6-7 Opening the Slot Cover Lock Before installing an expansion card, remove the expansion slot cover or the existing expansion card.
  • Page 43 If you are removing a standard PCI card or PCI Express x1 card, hold the card at each end, and carefully rock it back and forth until the connectors pull free from the socket. Pull the expansion card straight up from the socket then away from the inside of the chassis to release it from the chassis frame.
  • Page 44 If you are not installing a new expansion card, install an expansion slot cover to close the open slot. CAUTION: After removing an expansion card, you must replace it with a new card or expansion slot cover for proper cooling of internal components during operation. To install a new expansion card, hold the card just above the expansion socket on the system board then move the card toward the rear of the chassis so that the bottom of the bracket on the card slides into the small slot on the chassis.

  • Page 45: Cable Management

    Connect external cables to the installed card, if needed. Connect internal cables to the system board, if needed. Replace the computer access panel. Reconnect the power cord and any external devices, then turn on the computer. Lock any security devices that were disengaged when the access panel was removed. Reconfigure the computer, if necessary.

  • Page 46: Cable Connections

    Grasp the cable end of the connector and pull it straight up (2). CAUTION: Always pull the connector - NEVER pull on the cable.
