DDR4 Memory Support for 2nd Gen Intel Xeon Scalable-SP Processors
Notes:
1.
2933 MHz memory support in two-DIMMs per-channel (2DPC) configuration can
be achieved by using memory purchased from Supermicro.
2.
Support for 2933 MHz memory
is dependent on the CPU SKU.
3.
16Gb-based memory modules are supported by 2nd Gen
Intel Xeon Scalable-SP processors only.
