Rules for Memory Expansion
Note the following rules when expanding system memory:
y DIMMs must be installed in pairs. A pair consists of two identical fully buffered
DIMMs of the same speed, capacity, and number of ranks.
y DIMMs must be loaded from the inside row of slots first before moving toward the
outside row of slots. Do not leave an empty slot between two populated DIMM slots.
For the best performance, install two memory boards in a cell. Both memory boards
should be populated with the same type of DIMMs and have the same memory capacity
installed.
