Memory Channel Mode NOTE: This option is available on select servers. Memory Channel Mode sets the memory to work in Lockstep or Non-Lockstep mode. Options include: • Independent Channel Mode (Non-Lockstep) (default)-Uses the standard error correction mechanism of Advanced ECC. • Combined Channel Mode (Lockstep)-Provides maximum data protection by allowing multiple-bit memory errors to be corrected in certain instances not possible in Advanced ECC mode. NOTE: Lockstep Mode (used for Intel servers) and Memory Channel Mode (used for AMD servers) provide the same functionality, allowing the memory controller to correct up to 8 bad bits that are byte aligned. Activating Combined Channel Mode has some memory population rules. For more information, see the user guide or QuickSpecs for the server. Advanced Options menu 141
