Server ECC Registered DDR4

This OWC 16GB DDR4 2933MHz CL21 module is a 288-pin ECC Registered DIMM built for Dell PowerEdge XR4510c and XR4520c servers. It operates at 1.2V with a 2Rx8 rank configuration and carries the PC4-23400 designation for server-grade reliability.

Workstation and server upgrades only

It suits administrators expanding memory in compatible Dell PowerEdge platforms or maintaining existing infrastructure with validated replacements. It will not work in standard desktop computers and cannot be mixed with unbuffered memory modules, so consumer PC builders should look elsewhere.

16GB capacity with backward speed support

The single module provides 16GB of registered ECC capacity for virtualisation, database or file-serving workloads. It runs at 2933MHz and is backward compatible with 2133MHz, 2400MHz and 2666MHz bus speeds, so it integrates into mixed-speed configurations without manual tuning.

Questions about this item

My Dell PowerEdge XR4510c currently runs 2666 MHz DDR4 — will this 2933 MHz CL21 module run at the lower speed without issues?

Yes, the module is backward compatible with 2133 MHz, 2400 MHz and 2666 MHz DDR4, so it will operate at your system's native speed.

Does my server need to support ECC registered DDR4 DIMMs for this 16 GB 288-pin kit to function?

Yes, this is ECC registered DDR4 memory and will only work in servers or workstations that accept registered DIMMs; it cannot be used in standard desktops or mixed with unbuffered modules.

After installation, how can I confirm the module is recognised as 16 GB DDR4 2933 CL21 ECC registered?

Check the BIOS or UEFI memory information screen — it should show 16 GB capacity, 2933 MT/s speed, CL21 latency and ECC registered status.
