Memory Installation; Memory Population For The 3Rd Gen Intel Xeon Scalable Processors - Supermicro SuperWorkstation 740A-T User Manual

Memory Installation

The X12DAi-N6 supports up to 4 TB of 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 4
TB of Intel Optane PMem 200 Series with speeds of up to 3200 MHz. (See the notes below.)
Notes: PMem 200 Series are supported on 3rd Gen Intel Xeon Scalable Platinum, Gold and
selected Silver processors. Memory speed support depends on the processors used in the
system.

Note: To maximize memory performance, please use the memory configurations marked with
"*" above (also shaded in orange) as these configurations are recommended by Supermicro
for optimal memory performance. Memory DIMM capacities larger than 64GB may only be
supported under certain conditions, please contact Supermicro technical support for additional
information.
