2.3 Memory Support and Population
Important:
Exercise extreme care when installing or removing DIMM modules to pre-
vent any possible damage.
Memory Support
The X11SDW-4C/8C/16C-TP13F motherboard supports up to 256GB of ECC RDIMM or
512GB of ECC LRDIMM DDR4 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.
