Your system contains 8 memory sockets split into two sets of four sockets. DIMMs in sockets A1 to A8 are assigned to processor 1. Each
4-socket set is organized into two channels. In each channel of the 4-socket set, the release levers of the first socket are marked white
and those of the second socket are marked black.

General memory module installation guidelines
Your system supports Flexible Memory Configuration, enabling the system to be configured and run in any valid chipset architectural
configuration. The following are the recommended guidelines for installing memory modules:
•
x4 and x8 DRAM based DIMMs can be mixed. For more information, see the Mode specific guidelines section.
•
Up to two dual- or single-rank RDIMMs can be populated per channel.
•
Populate DIMM sockets only if a processor is installed. For single-processor systems, sockets A1 to A8 are available.
•
Populate all sockets with white release levers first, and then all the sockets with black release levers.
•
When mixing memory modules with different capacities, populate the sockets with memory modules with highest capacity first. For
example, if you want to mix 4 GB and 8 GB DIMMs, populate 8 GB DIMMs in the sockets with white release levers and 4 GB DIMMs in
the sockets with black release levers.
•
Memory modules of different capacities can be mixed provided other memory population rules are followed (for example, 4 GB and 8
GB memory modules can be mixed).
•
Mixing of more than two DIMM capacities in a system is not supported.
•
Populate two DIMMs per processor (one DIMM per channel) at a time to maximize performance.
