Product Description
IBM EM54 64GB DDR5 Memory for Power11
The IBM EM54 is a 64 GB DDR5 memory feature for IBM Power11 servers. It consists of two 32 GB DDIMMs.
Product Description
The IBM EM54 (feature code EM54, part number 03HD880, CCIN 32A1) is a 64 GB memory feature made of two 32 GB low-profile DDR5 DDIMMs. Each module uses 16 Gb DRAM and runs at 4000 MHz or 4800 MHz depending on the processor type. The feature uses two DDIMM slots. It is the Power11 feature code for the same 32 GB DDR5 module ordered as EMFA on Power10. Do not mix this DDR5 feature with DDR4 memory in the same system.
