Memory Support
Each CPU board supports up to 1.5 TB of DDR4 3DS Load Reduced (3DS LRDIMM), Load
Reduced (LRDIMM), or Registered (RDIMM) ECC 2666 Mhz memory in 12 slots. With eight
CPU boards installed, your system will support up to 12 TB of DDR4 3DS LRDIMM, LRDIMM,
or RDIMM ECC memory in 96 slots
Notes: 1. Memory speed support is dependent on the CPUs used in the system. For the latest
CPU/memory updates, please refer to our website at http://www.supermicro.com/products/
