Chapter 2: Installation
Note
: 2400MHz memory speed is only supported when using 16GB DDR4 RDIMM
ECC memory.
2.3 Memory Support and Installation
Note
: Check the Supermicro website for recommended memory modules.
Important:
Exercise extreme care when installing or removing DIMM modules to pre-
vent any possible damage.
Memory Support
The X10SDE-DF supports DDR4 VLP ECC memory; up to 64GB of unbuffered (UDIMM)
memory or up to 128GB of registered (RDIMM) memory in four memory slots per node. Node
1 has slots P1-DIMMA1, P1-DIMMA2, P1-DIMMB1, and P1-DIMMB2. Node 2 has slots P2-
DIMMA1, P2-DIMMA2, P2-DIMMB1, and P2-DIMMB2. 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.
DIMM Module Population Configuration
For optimal memory performance, follow the table below when populating memory.
