NOTE
: Memory congurations that fail to observe these guidelines can prevent your system from booting, stop responding
during memory conguration, or operating with reduced memory.
The system supports Flexible Memory Conguration, enabling the system to be congured and run in any valid chipset architectural
conguration. The following are the recommended guidelines for installing memory modules:
x4 and x8 DRAM based memory modules can be mixed. For more information, see the Mode-specic 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. For dual-processor
systems, sockets A1 to A8 and sockets B1 to B4 are available.
Populate all sockets with white release levers rst, and then all the sockets with black release levers.
When mixing memory modules with dierent capacities, populate the sockets with memory modules with highest capacity rst. For
example, if you want to mix 4 GB and 8 GB memory modules, populate 8 GB memory modules in the sockets with white release tabs
and 4 GB memory modules in the sockets with black release tabs.
In a dual-processor conguration, the memory conguration for each processor should be identical. For example, if you populate socket
A1 for processor 1, then populate socket B1 for processor 2, and so on.
Memory modules of dierent 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 memory module capacities in a system is not supported.
Populate two DIMMs per processor (one DIMM per channel) at a time to maximize performance,

Four memory channels are allocated to each processor. The allowable congurations depend on the memory mode selected.
