Chapter 2: Installation
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 X11SSQ/-V motherboard supports up to 64GB of Unbuffered (UDIMM) DDR4 Non-ECC
1866/2133 MHz in four memory slots. The X11SSQ-L supports up to 32GB in two slots:
DIMMA1 and DIMMB1. 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.
Note: Be sure to use memory modules of the same type and speed on the motherboard.
Mixing of memory modules of different types and speeds is not allowed.
DIMM Module Population Conguration
For optimal memory performance, follow the table below when populating memory.

DIMM Module Population Sequence
When installing memory modules on the X11SSQ/-V, the DIMM slots must be populated in the
following order: DIMMA2, DIMMB2, then DIMMA1, DIMMB1. The blue slots must be populated
rst. On the X11SSQ-L, populate DIMMA1 initially and then DIMMB1.
