8GB DDR4-2933 ECC Registered Module

This 8GB DDR4-2933 RDIMM adds ECC registered memory capacity to compatible servers and workstations. It targets administrators who need single-module upgrades for validated platforms requiring registered DIMMs with error correction.

Capacity and headroom at PC4-23400

The single 8GB rank operates at DDR4-2933 with CL21 latency and 1.20V voltage. It handles typical virtualisation and database workloads within the module limit; larger datasets or multi-socket configurations will require additional DIMM slots and higher aggregate capacity.

RDIMM signal integrity and parity checking

The registered design performs parity checking to detect improper addresses or commands, improving signal integrity for heavy workloads. No extra accessories or software are bundled with the memory module itself.

Questions about this item

Will this 2933 MHz RDIMM work alongside my existing registered ECC modules?

The module runs at DDR4-2933 with CL21 latency and 1.20 V. Compatibility depends on your platform's memory controller and its qualified-vendor list.

How can I confirm the module is detected at 2933 MHz with ECC active?

Check the BIOS memory information screen or run a tool such as dmidecode; it should report 8 GB, DDR4-2933, registered, ECC enabled.

What comes in the box and do I need anything else to install it?

You receive the 8 GB 288-pin RDIMM only. No cables, brackets or additional parts are required for installation.
