Server memory upgrade

This OWC module is a 16GB DDR4 ECC Registered RDIMM built for servers, workstations and NAS systems. It runs at 2400MHz with CL17 latency and operates at 1.2V using a 2Rx4 rank configuration.

Check your platform

Verify that your motherboard and CPU support DDR4 ECC Registered memory before ordering. This module will not work in standard desktop computers and cannot be mixed with unbuffered DIMMs. Confirm the system accepts 288-pin RDIMMs and the required voltage.

Sustained operation

The JEDEC-compliant design is tested for continuous workloads typical in server environments. Error-correcting code detects and corrects single-bit errors during extended use while the registered buffer reduces electrical load on the memory controller for stable long-term performance.

Questions about this item

Does the 16GB DDR4 2400 CL17 2Rx4 ECC Registered RDIMM come with any cables, brackets or tools, or must they be bought separately?

The module ships alone. No cables, brackets or tools are included; server memory installs directly into a 288-pin DDR4 slot without extra parts.

Should I choose the 16GB 2Rx4 CL17 2400MHz kit or a different capacity or rank for my server?

Select the 16GB 2Rx4 CL17 module when your platform requires a single registered ECC DIMM at 2400MHz; match capacity and rank to the motherboard’s qualified-vendor list.

What does the PC4-19200 2400MHz CL17 rating mean once the 2Rx4 ECC RDIMM is installed in a live server?

It indicates a peak transfer rate of 19200 MB/s at 2400MHz with 17-cycle CAS latency, delivering registered ECC bandwidth for workloads that demand error correction.
