Memory Support for the Motherboard
The motherboard supports up to 3072 GB of Load Reduced (LRDIMM),
Registered (RDIMM) or Non-volatile (NV-DIMM) DDR4 (288-pin) ECC 2400 MHz
(max.) in 24 slots. Memory speed support depends on the CPUs installed in the
motherboard. For the latest memory updates, please refer to our website at http://
www.supermicro.com/products/motherboard.
