32GB DDR4-2133 ECC LRDIMM with CL15 latency and 1.20V operation for IBM-compatible servers
This 288-pin registered module delivers 32 GB of DDR4 memory at 2133 MT/s with CL15 latency and 1.20 V operation. It uses a 4Rx4 organisation and major-brand DRAM to provide error-correcting code protection for server platforms.
The stick targets administrators upgrading or repairing compatible IBM servers that accept 2133 MHz registered LRDIMMs. It is not for desktop boards that only support unbuffered UDIMMs, nor for platforms limited to lower capacities or different voltage requirements.
Registered buffering and ECC maintain data integrity during sustained read-write cycles typical of virtualisation or database tasks. The 1.20 V design keeps power draw consistent, while matched major-brand ICs ensure uniform timing across all populated slots.

Yes, the module requires a DDR4 slot that accepts 288-pin ECC registered LRDIMMs running at 2133 MT/s with 1.20V.
Mixing ranks is possible if the server BIOS supports it, but population rules vary by platform; check the system manual for supported rank-per-channel limits.
Enter the BIOS or use an OS tool such as dmidecode to confirm the reported speed is 2133 MT/s, voltage 1.20V, and CAS latency 15.
