Product Description
The IBM EM5B 128 GB (2x64 GB) DDIMMs, 4000 MHz or 4800 MHz, 16 Gbit DDR5 Memory (Feature Code: EM5B) is a high-performance DDR5 memory kit designed for IBM Power Systems. This dual-module kit provides 128 GB total capacity using two 64 GB DDR5 RDIMMs with 16 Gbit DRAM technology, supporting speeds up to 4800 MHz (or 4000 MHz depending on system configuration). It delivers increased bandwidth, lower power consumption, and improved reliability for demanding IBM i workloads.

Compatibility The IBM EM5B 128 GB (2x64 GB) DDIMMs are compatible with IBM Power Systems running IBM i, including Power11 models such as 9824-22A (Power S1122), 9824-42A (Power S1124), and select Power10 models upgraded to DDR5-capable configurations (e.g., 9105-41B Power S1014, 9105-22A Power S1022, 9105-42A Power S1024, 9043-MRX E1050, 9080-HEX E1080). They are supported in systems allowing DDR5 memory (no mixing with DDR4 in the same node). Memory must be installed in balanced pairs or groups per system guidelines for optimal performance. Not compatible with DDR4-only slots or non-supported processor configurations.
