Memory Support
The X12DPG-AR supports up to 4TB 3DS LRDIMM/LRDIMM/3DS RDIMM/RDIMM DDR4
(288-pin) ECC memory with speeds of 3200/2933/2666 MHz in 16 memory slots and up to
4TB Intel Optane PMem 200 Series with speeds of up to 3200 MHz. (See the notes below.)
Note 1:
Intel® Optane™ Persistent Memory (PMem) 200 Series are supported by the
3rd Gen Intel Xeon Scalable (83xx/63xx/53xx/4314 Series) Processors.
Note 2:
Memory speed support depends on the processors used in the system.
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.
