The Kingston KSM48R40BD4TMM-128HMI is a 128GB DDR5 ECC registered memory module (RDIMM) for server and workstation systems. It runs at DDR5-4800 with a CAS latency of 40 and operates at 1.1V in a 288-pin RDIMM form factor.
The module supports ECC with Single Error Correction Double Error Detection (SECDED), and its registered design suits multi-module configurations. It includes an on-module thermal sensor and is rated for an operating temperature range of 0–85°C.
Listed compatibility covers Intel Xeon W and Xeon Scalable (3rd Gen and later) platforms as well as AMD EPYC workstation platforms. It is suited to memory-intensive workloads such as virtualisation, databases and data-heavy applications, where error correction helps maintain data integrity.
