  • Page 20: Installing Dimms

    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 other two 1-GB DIMMs.
  • Page 21 Open both latches of the memory module socket (1), and insert the memory module into the socket (2). NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket. Populate the black DIMM sockets before the white DIMM sockets.
