Memory options
|
IMPORTANT: This server does not support mixing LRDIMMs or RDIMMs. Attempting to mix any combination of these DIMMs can cause the server to halt during BIOS initialization. |
The memory subsystem in this server can support LRDIMMs or RDIMMs:
- RDIMMs offer address parity protection.
- LRDIMMs support higher densities than single-rank and dual-rank RDIMMs. This support enables you to install more high-capacity DIMMs, resulting in higher system capacities and higher bandwidth.
All memory types are referred to as DIMMs when the information applies to all types. When specified as LRDIMM or RDIMM, the information applies to that type only. All memory installed in the server must be of the same type.
Memory speed
Maximum operating memory speed is a function of the following:
- Rated DIMM speed
- Processor model
- The speed selected in the BIOS/Platform Configuration (RBSU) of the UEFI System Utilities
The server supports the following DIMM speeds:
- Single-rank and dual-rank PC4-2400 (DDR4-2400) RDIMMs operating at up to 2400 MT/s
- Quad-rank PC4-2400 (DDR4-2400) LRDIMMs operating at up to 2400 MT/s
