H8DCE User's Manual Notes: X indicates a populated DIMM slot. If adding at least four DIMMs (with two CPUs installed), the confi gurations with DIMMs spread over both CPUs (and not like the con- fi guration in row 5) will result in optimized performance. Note that the fi rst two DIMMs must be installed in the CPU1 memory slots.
