8 GB DDR4 2933 ECC Registered DIMM

This 288-pin DDR4 module delivers 8 GB of registered ECC memory rated at 2933 MT/s with CL21 21-21-21 timings. It is built for servers and workstations that require error correction and registered signalling for stable operation under continuous load.

Suited for single-rank capacity upgrades

Administrators expanding virtualisation hosts or high-performance compute nodes will benefit from the registered ECC design. Systems that require unbuffered non-ECC modules or higher-density multi-rank sticks cannot use this DIMM.

Maintains rated speed

The registered buffer reduces electrical loading on the memory controller, helping the module hold 2933 MT/s throughput during extended virtual machine or deep-learning runs. ECC circuitry continues to detect and correct single-bit errors throughout prolonged operation.

Questions about this item

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

It installs in a standard 288-pin DDR4 DIMM slot on a server motherboard that supports registered ECC memory.

Will this CL21 registered ECC module run at 2933 MT/s when paired with older DDR4 sticks rated at a lower speed?

The system will downclock all modules to the speed of the slowest installed stick, so this module will operate at that lower rate.

How can I confirm the module is running at PC4-23400 with CL21 timing after installation?

Check the memory speed and latency reported in the server BIOS or a hardware utility such as CPU-Z to verify 2933 MT/s and 21-21-21 timings.
