  • Page 41: Memory

    Memory The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3- SDRAM) 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 high- performing dual channel mode.

  • Page 42: Populating Dimm Sockets

    Populating DIMM Sockets There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM2 and DIMM4 operate in memory channel A. Sockets DIMM1 and DIMM3 operate in memory channel B. Figure 7-5 DIMM Socket Locations Table 7-1...

  • Page 43: Installing Memory Modules

    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 2-GB DIMM, and three 1-GB DIMMs, Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel B should be populated with the two 1-GB DIMMs.
