  • 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 XMM3 operate in memory channel A. Sockets XMM2 and XMM4 operate in memory channel B. Figure 2-5 DIMM Socket Locations Item...

  • Page 21: Installing Dimms

    ● If a single DIMM is installed, it must be installed in the XMM4 socket. ● In either 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.
  • Page 22 Open both latches of the memory module socket (1), and insert the memory module into the socket (2). Figure 2-6 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.
