2.4 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 X11SSW-TF/-4TF motherboard supports up to 64GB of unbuffered (UDIMM) DDR4
ECC 2400/2133/1866/1600MHz memory in four memory slots. Populating these DIMM slots
with 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.
