2.4 Memory Support and Installation
Notes: 1)Check the Supermicro website for recommended memory modules. 2)Exer
cise extreme care when installing or removing DIMM modules to prevent any damage.
Memory Support
The motherboard supports up to 4TB of 3DS LRDIMM (3DS Load Reduced DIMM), LRDIMM,
2933*/2666/2400/2133 MHz memory in 16 slots (*Note 1 below). This motherboard also
supports up to 5TB memory with DCPMM modules installed based on the DCPMM population
table on page 38. The black DIMM slots are reserved for DCPMM support. (Please refer
Note: 1. Support for 2933 MHz memory is dependent on the CPU SKU. 2. Populat

Memory Installation Sequence
Memory modules for the X11 UP/DP/MP motherboards are populated using the "Fill First"
the channel, and the black slot, the second module of the channel. When installing memory
To maximize memory capacity and performance, please populate all DIMM slots on the
motherboard, including all blue slots and black slots.
General Memory Population Requirements
1. Be sure to use the memory modules of the same type and speed on the motherboard.
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.
