16GB DDR4 2933 ECC UDIMM for servers

This 16GB DDR4 2933 ECC UDIMM module is built for server and workstation systems that require error-correcting memory. It operates at 2933MHz with a CL21 latency and standard 1.20V voltage. The unbuffered 2Rx8 design suits platforms that accept ECC UDIMMs rather than registered DIMMs. Buyers who need registered memory or higher capacities per slot cannot use this module.

Simple 288-pin DIMM installation

The 288-pin DIMM form factor fits standard DDR4 UDIMM slots found in compatible servers and workstations. Installation follows the usual procedure: align the notch, press firmly until the retention clips engage, and verify detection in BIOS or the operating system. Problems usually arise when the platform expects registered DIMMs or does not support ECC UDIMMs at this speed, so confirming the system memory specifications before purchase avoids incompatibility.

Stable throughput under sustained load

With ECC active, the module corrects single-bit errors on the fly, maintaining data integrity during extended workloads such as virtualisation, database serving or rendering farms. The major-brand chipset and 1.20V operation keep power draw consistent, while the CL21 timing delivers predictable latency without aggressive tuning. Continuous operation at the rated 2933MHz speed is sustained by the validated components and testing regime.

Questions about this item

How can I confirm the module is running at DDR4 2933 CL21 with ECC active after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should report 2933 MT/s, CAS latency 21, 1.20 V and ECC enabled for the installed DIMM.

What comes in the box and do I need any extra parts such as cables or brackets?

The package contains a single 16 GB 288-pin DDR4 UDIMM; no cables, brackets or additional components are required for installation in a compatible server or workstation.

Which version should I choose if my service manual lists the IBM-Lenovo part number 4X71B32812?

Select this 16 GB DDR4 2933 ECC UDIMM 2Rx8 CL21 1.20 V module; it is a direct equivalent for the 4X71B32812 part number.
