128GB DDR5 ECC RDIMM for Servers

This single 128GB DDR5 5200 CL42 4Rx4 registered DIMM is built for workstations, servers and NAS systems that require ECC error correction. It runs at 1.1V and conforms to JEDEC PC5-41600 specifications for enterprise environments.

Straightforward 288-pin installation

The module seats in a standard DDR5 RDIMM slot without tools or heat-spreader clearance issues. The most common mistake is attempting to mix this registered ECC memory with unbuffered or load-reduced DIMMs, which the platform will not support.

Verify registered ECC support first

Confirm your motherboard or server platform explicitly lists DDR5 registered ECC RDIMM compatibility and 4Rx4 rank support before ordering. Standard desktop boards and consumer laptops cannot use this module, and mixing registered with unbuffered memory will prevent boot.

Perguntas sobre este artigo

How do I confirm the 128GB DDR5 5200 module is running at CL42 after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should report DDR5 5200 speed with a CAS latency of 42 for the installed 128GB module.

What comes with the OWC 5R2D54R4128G module and what must be sourced separately?

The box contains a single 128GB 288-pin DDR5 ECC Registered RDIMM; no heat spreader or extra cables are included, and any additional DIMMs or cooling must be purchased separately.

When should I choose this 128GB 4Rx4 DDR5 5200 CL42 1.1V RDIMM over other capacities?

Select this 128GB 4Rx4 module when your workstation or server requires maximum registered ECC capacity per slot at the standard 5200 CL42 1.1V specification.
