128GB DDR4 ECC Registered RDIMM

This single 128GB DDR4 module delivers registered ECC memory for servers, workstations and NAS systems. It operates at 2400MHz with CL17 latency and 1.2V power draw. The 4Rx4 rank configuration targets high-density slots in compatible enterprise platforms.

Capacity and headroom at 128GB

A 128GB stick provides substantial headroom for virtualisation, large databases and memory-intensive workloads. Registered signalling and ECC protect data integrity under sustained load. Systems limited to lower per-slot capacities or unbuffered memory cannot use this module.

Build quality and 288-pin mounting

The module follows JEDEC DDR4 standards with 288-pin gold contacts and no heat spreader. Registered buffering reduces electrical load on the memory controller, enabling stable operation in multi-DIMM configurations. Compatibility is restricted to platforms that explicitly support DDR4 registered ECC RDIMMs.

Perguntas sobre este artigo

Will this 128GB DDR4 2400MHz 4Rx4 registered ECC module work alongside older DDR4 RDIMMs already in my server?

It will only work if the existing modules are also DDR4 registered ECC at 1.2V; mixing with unbuffered or non-ECC DIMMs is not supported and the platform may downclock all memory to the slowest common speed.

How can I verify the 128GB module is running at PC4-19200 CL17 after installation?

Check the BIOS memory information or an OS tool such as dmidecode; it should report 2400 MT/s, CAS 17, 1.2V, registered ECC, and a single 128GB 4Rx4 rank configuration.

Does the box contain only the 288-pin RDIMM or are any cables, brackets or additional parts included?

The package contains the single 128GB DDR4 2400MHz CL17 4Rx4 registered ECC RDIMM only; no cables, brackets, heat spreaders or other accessories are supplied.
