Installing Additional Memory The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2SDRAM) 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. To achieve the maximum memory support, you can populate the system board with up to 4 GB of memory configured in a highperforming dual channel mode.
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.
● If a single DIMM is installed, it must be installed in the XMM3 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. 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.
7. 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. A DIMM must occupy the XMM3 socket. Always populate XMM3 before XMM1, and XMM4 before XMM2 (populate the black sockets before white sockets in each channel).
Removing or Installing an Expansion Card The computer has two standard PCI expansion slots that can accommodate an expansion card up to 17.46 cm (6.875 inches) in length. The computer also has one PCI Express x1 expansion slot and one PCI Express x16 expansion slot.
