IBM 95Y4823 - 16GB TruDDR4 (2Rx4, 1.2V) PC4-17000 CL15 2133MHz LP RDIMM
The IBM 95Y4821 / 95Y4823 / 00NU400 16GB TruDDR4 RDIMM is an enterprise server memory module designed for compatible IBM and Lenovo System x server platforms. It provides reliable DDR4 registered memory for supported systems requiring 2133MHz ECC RDIMM technology.
This memory module provides 16GB capacity and operates at DDR4-2133 (PC4-17000) speeds with CL15 latency. Its dual-rank x4 (2Rx4) organization, 1.2V operating voltage, and registered DIMM architecture are designed for enterprise server environments where memory reliability and scalability are important.
The 95Y4821 / 95Y4823 / 00NU400 is suitable for memory upgrades, replacement of failed DIMMs, server expansion, and maintaining spare memory inventory. Typical applications include virtualization, databases, business applications, file services, and general enterprise computing workloads.
This is a 16GB DDR4 ECC Registered DIMM (RDIMM) and should not be mixed with incompatible DIMM technologies such as LRDIMM or unbuffered memory unless specifically supported by the server platform. Exact server compatibility, memory population rules, supported speeds, and existing DIMM configuration should be verified before installation.
