Server memory upgrade

This 32 GB DDR4 module runs at 2933 MHz with CL21 latency and 1.20 V operation. It uses ECC registered DIMM architecture with a 2Rx4 rank layout on a 288-pin form factor. Major brand chips provide the reliability expected in server and workstation environments.

IT administrators and integrators

Suitable for technicians upgrading or repairing IBM-Lenovo platforms that specify the listed part numbers. The registered design and ECC function require a compatible motherboard; desktop boards that accept only unbuffered non-ECC memory cannot use this module. Buyers who need unbuffered DIMMs or higher frequencies should look elsewhere.

Capacity and headroom

A single 32 GB stick adds substantial memory headroom for virtualisation hosts, database nodes or compute clusters. The 2933 MHz rating matches common server memory buses, so the module runs at rated speed without overclocking. Workloads that demand capacities beyond a single DIMM slot or speeds above PC4-23400 will require additional modules or a different platform.

Questions about this item

What motherboard slot and DDR generation does this 288-pin DDR4 RDIMM require?

It fits a standard DDR4 DIMM socket with 288 pins and registered buffering.

Can I mix this CL21 2933 MHz ECC module with slower DDR4 RDIMMs already installed?

The system will run all modules at the speed and timings of the slowest installed stick.

How do I confirm the module is recognised as 32 GB ECC registered memory at 2933 MHz after installation?

Check the BIOS memory information or run a system tool such as dmidecode to verify capacity, speed and ECC status.
