Loading rules
• Load the memory modules in order of size, starting with the largest module and nishing with the smallest module.
• For a single processor conguration, the DIMMs should be loaded starting with the DIMM furthest from the CPU, with the
rst DIMM loaded in the socket on the right side of the system and alternating sides of the CPU.
• For a dual processor conguration, follow the loading order above, but alternate between the two processors.
• See gures below for loading order.
