  • Page 19: Installing Additional Memory

    Installing Additional Memory The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2- 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.
  • Page 20: Populating Dimm Sockets

    Populating DIMM Sockets There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A. Sockets XMM3 and XMM4 operate in memory channel B. Figure 2-6 DIMM Socket Locations Table 2-1...
  • Page 21: Installing Dimms

    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.
  • Page 22 Open both latches of the memory module socket (1), and insert the memory module into the socket (2). Figure 2-7 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 23: Removing Or Installing An Expansion Card

    Removing or Installing an Expansion Card The computer has two standard PCI expansion slots, one PCI Express x1 expansion slot, and one PCI Express x16 expansion slot. The expansion slots accommodate full-height or half-height expansion cards. Figure 2-8 Expansion Slot Locations Table 2-2 Expansion Slot Locations Item...
  • Page 24 Remove the computer access panel. Locate the correct vacant expansion socket on the system board and the corresponding expansion slot on the back of the computer chassis. 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.
  • Page 25 NOTE: Before removing an installed expansion card, disconnect any cables that may be attached to the expansion card. If you are installing an expansion card in a vacant socket, you must use a flatblade screwdriver to pry out the metal shield on the rear panel that covers the expansion slot. Be sure to remove the appropriate shield for the expansion card you are installing.
  • Page 26 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. Be sure not to scrape the card against the other components. Figure 2-12 Removing a PCI Express x16 Expansion Card Store the removed card in anti-static packaging.
  • Page 27 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. Press the card straight down into the expansion socket on the system board.
