Memory The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3SDRAM) dual inline memory modules (DIMMs). DDR3-SDRAM 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 8 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. Populate the DIMM sockets in the following order: DIMM1 then DIMM2 Figure 6-4 DIMM Socket Locations Table 6-1 DIMM Socket Locations Item Description Socket Color Insertion Order 1 DIMM1 socket, Channel A (populate first) White 1 2 DIMM2 socket, Channel A White 2 NOTE: A DIMM must occupy the DIMM1 socket.
● The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not equal to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel populated 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.
4. Open both latches of the memory module socket (1), and insert the memory module into the socket (2). Figure 6-5 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 DIMM1 socket. Always populate the blue sockets before the black sockets in each channel. To create a dual-channel memory configuration, the memory capacity of Channel A must equal the memory capacity of Channel B.
