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 XMM2 operate in memory channel A. Sockets XMM3 and XMM4 operate in memory channel B.
one channel should be populated with the 1GB DIMM and one 256MB DIMM and the other channel should be populated with the two 512MB DIMMs. With this configuration, 2 GB will run as dual channel and 256 MB will run as single channel. ● In any 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.
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. For maximum performance, populate the sockets so that the memory capacity is spread as equally as possible between Channel A and Channel B. Refer to Populating DIMM Sockets for more information. 8.
