Rules for Memory Expansion

Note the following rules when expanding system memory:

yDIMMs must be installed in pairs. A pair consists of two identical fully buffered DIMMs of the same speed, capacity, and number of ranks.

yDIMMs 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.
