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 X11SRL-F supports up to 512GB of RDIMM and 1TB of LRDIMM DDR4 (288-pin) ECC
memory with speeds of up to 2933 MHz in eight memory slots.
Refer to the tables below for
the recommended DIMM population order and additional memory information.
