OWC 32GB DDR4 2666 ECC Registered DIMM

This is a single 32GB DDR4 2666 PC4-21300 CL19 2Rx4 VLP 288-pin 1.2V ECC Registered DIMM from OWC. It is designed as a memory upgrade for select workstations, servers, and NAS systems that require registered ECC modules.

Suits systems needing registered ECC memory.

This module suits administrators upgrading or repairing enterprise platforms that specifically call for registered ECC DDR4 memory. It will not work in standard desktop computers that require unbuffered non-ECC memory, nor can it be mixed with unbuffered or load-reduced ECC modules.

32GB capacity per module

The 32GB capacity per DIMM allows high-density configurations within the slot limits of compatible server and workstation motherboards. Each module operates at DDR4 2666 with CL19 latency at 1.2V.

Questions about this item

Does the 288-pin VLP RDIMM fit in a standard-height server DIMM slot?

Yes, the very-low-profile form factor uses the standard 288-pin DDR4 connector and fits in any slot that accepts registered DDR4 DIMMs.

What BIOS setting is commonly missed when installing this registered ECC module?

Enable ECC and registered-memory support in the BIOS; the module will not train correctly if the platform expects unbuffered memory.

How can I tell when this 32 GB 2Rx4 kit should be replaced?

Replace it if the system logs correctable ECC errors that increase over time or if memory diagnostics report uncorrectable failures.
