  • Page 19: Installing Additional Memory

    Installing Additional Memory The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2- SDRAM) 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.

  • Page 20: 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 DIMM1 and DIMM2 operate in memory channel A. Sockets DIMM3 and DIMM4 operate in memory channel B. Figure 2-6 DIMM Socket Locations Table 2-1...

  • Page 21: Installing Dimms

    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. If one channel will have more memory than the other, the larger amount should be assigned to Channel A.
