3 Memory Support
The X11 UP/DP/MP motherboard supports 3DS LRDIMM (3DS Load Reduced DIMM)/
LRDIMM (Load Reduced DIMM)/3DS RDIMM (3DS Registered DIMM)/RDIMM (Registered
DIMM), DDR4 (288-pin) ECC 2133/2400/2666/2933* MHz memory modules (*Note below).
Refer to the following tables for detailed information on memory support for the X11 UP/DP/
MP motherboards.
Notes: 1. 2933 MHz memory is supported by the 2nd Gen Intel Xeon Scalable-SP
(82xx/62xx series) processors only. 2. 16Gb-based memory modules are supported
by 2nd Gen Intel Xeon Scalable-SP processors only. 3. Populating DDR4 memory
modules in a two-DIMM per-channel (2DPC) confi guration may affect memory band-
width and performance.
