DIMMs The memory sockets on the system board can be populated with up to two industry-standard DIMMs (model 400) or four industry-standard DIMMs (model 490) .
  • Page 58: Populating Dimm Sockets (model 400)

    Populating DIMM sockets (Model 400) There are two DIMM sockets on the system board, with one socket per channel. The sockets are labeled DIMM1 and DIMM3. Socket DIMM1 operates in memory channel B. Socket DIMM3 operates 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.
  • Page 59: Installing Dimms

    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.
  • Page 60 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). Repeat steps 3 and 4 to install any additional modules. The computer should automatically recognize the additional memory the next time you turn on the computer.

  • Page 63 NOTE: System board appearance and PCI expansion sockets may vary. If you are installing an expansion card in a vacant socket, you must slide one of the expansion slot covers up and out of the chassis or use a flatblade screwdriver to pry out one of the metal shields on the rear panel that covers the expansion slot.
  • Page 64 If you are removing a PCI Express x16 card, pull the retention arm on the back of the expansion socket away from the card and carefully rock the card back and forth until the connectors pull free from the socket. Lift the card straight up then away from the inside of the chassis to remove it.
  • Page 65 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 (1) so that the bottom of the bracket on the card slides into the small slot on the chassis. Press the card straight down into the expansion socket on the system board (2).
