Memory The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2SDRAM) dual inline memory modules (DIMMs). CAUTION: DDR and DDR2 memory modules are not interchangeable. 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.
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.
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. For example, if you are populating the sockets with one 1-GB DIMM, and three 512-MB DIMMs, Channel A should be populated with the 1-GB DIMM and one 512-MB DIMM, and Channel B should be populated with the two 512-MB DIMMs.
4. Open both latches of the memory module socket (1), and insert the memory module into the socket (2). Figure 7-8 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 XMM1 socket. Always populate the white sockets before the black sockets in each channel. In order to create a dual-channel memory configuration, the memory capacity of Channel A must equal the memory capacity of Channel B.
Expansion Cards 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.
