2.4 Memory Support and Installation

Notes: Check the Supermicro website for recommended memory modules. Exercise
extreme care when installing or removing DIMM modules to prevent any damage.

Memory Support

The motherboard supports up to 2TB of 3DS Load Reduced DIMM (3DS LRDIMM), 3DS
Registered DIMM (3DS RDIMM), or up to 1TB of Load Registered DIMM (LRDIMM), with
speeds of 2933*/2666/2400/2133/1866/1600/1333 MHz modules in 8 memory slots. (*Notes
below). Populating the DIMM slots in a 1DPC (one DIMMs per channel) configuration with
pairs of memory modules of the same type, speed, and size will result in interleaved memory,
which improves performance.
Notes: 1. Using unbalanced memory topology such as populating two DIMMs in one
channel while populating one DIMM in another channel on the same motherboard will
result in reduced memory performance. 2. Unbalanced memory configuration is not
recommended. 3. Support for 2933MHz memory is dependent on the CPU SKU. 4. The
memory capacity support will differ according to the processor SKUs. 5. 16Gb-based
memory modules are supported by 2nd Gen Intel Xeon Scalable-SP processors only.

General Memory Population Requirements

Be sure to use the memory modules of the same type and speed on the motherboard.
Mixing of memory modules of different types and speeds is not allowed.
