Memory Support and Installation
Note:
Check the Supermicro website for recommended memory modules. Exercise extreme
care when installing or removing DIMM modules to prevent any damage.
Memory Support
The X11DPU-V supports up to 6 TB of 3DS Load Reduced DIMM (3DS LRDIMM), 3DS
Registered DIMM (3DS RDIMM), or up to 3 TB of Load Registered DIMM (LRDIMM), with
speeds up to 2933 MHz modules in 24 memory slots (*
Notes
below). Populating these DIMM
modules with a pair of memory modules of the same type and size will result in interleaved
memory, which will improve memory performance.
Notes:
1.
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.
2.
When installing
memory modules, be sure to populate the first DIMM module on the blue memory slot,
which is the first memory slot of a memory channel, and then populate the second DIMM
in the black slot if 2DPC memory configuration is used.
3.
Memory speed is dependent on
the type of processors used in your system.
4.
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.
5.
Unbalanced memory
configuration is not recommended.
6.
2933 MHz memory is supported by 2nd Generation
Intel Xeon Scalable-SP (82xx/62xx series) processors only.
7.
The memory capacity support
will differ according to the processor SKUs.
Memory Installation Sequence
Memory modules for this motherboard are populated using the "Fill First" method. The blue
memory slot of each channel is considered the "first DIMM module" of the channel, and the
black slot, the second module of the channel. When installing memory modules, be sure to
populate the blue memory slots first and then populate the black slots.
General Memory Population Requirements
1. 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.
2. 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.
3. Populating memory slots with a pair of DIMM modules of the same type and size will
result in interleaved memory, which will improve memory performance.
