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. For example, if you are populating the sockets with one 1-GB DIMM, and three 512-MB DIMMs, Channel A should be populated with the 1-GB DIMM and one 512-MB DIMM, and Channel B should be populated with the two 512-MB DIMMs.
Page 117 WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system components to cool before touching. Open both latches of the memory module socket (1), and insert the memory module into the socket (2). Figure 8-30 Installing a DIMM NOTE: A memory module can be installed in only one way.
