IBM Power10 servers use next-generation, high-performance, high-reliability, high-function memory DIMMS that contain a buffer chip, intelligence, and 2666 MHz or 3200 MHz DRAM memory. IBM Memory DDIMMs are placed in DDIMM slots in the server system, are manufactured in two different form factors for installation in a Power10 server CEC based on its 2U or 4U height. The 2U high memory cards can be extended through spacers for use in 4U high servers, but the 4U high cards naturally do not fit in 2U servers. A minimum 32 GB of memory is required with single processor modules, and all Power10 memory DIMMs must be installed in pairs. Each IBM DIMM feature code includes two physical Memory DIMMs.
The following Power10 Memory features are supported in the following 2U server models IBM S1014 9105-41B, S1022 9105-22A and S1022s 9105-22B:
