OWC 5R6D54R4128G 128GB DDR5 5600 CL46 4Rx4 ECC Registered RDIMM memory upgrade

SKU CH-B5DD-33WZY

Single 128GB DDR5 5600 CL46 4Rx4 ECC registered RDIMM for select Supermicro SuperServer models

  • Capacity128GB
  • Type288-Pin DDR5 ECC RDIMM
  • SpeedDDR5 5600 (PC5 44800)
  • CAS Latency46
  • Voltage1.1V
  • ECCYes

Capacity 128GB

  • 128 GB single module expands server memory capacity
  • DDR5 5600 CL46 delivers high-speed data throughput
  • ECC registered design protects data integrity in critical workloads
  • 1 V operation reduces power draw per module
  • Qualified for Supermicro SuperServer SSG-121E-NE316R and listed compatible systems

Server-grade DDR5 ECC module

This 128GB registered DIMM targets Supermicro SuperServer platforms such as the SSG-121E-NE316R, SSG-121E-NES24R, SSG-221E-NE324R, SYS-111C-NR and SYS-111E-FDWTR. It is built for workloads that require error-correcting memory in workstations, NAS systems, servers and network switches. Standard desktop boards cannot use this module.

128GB single-stick capacity at 5600 MT/s

The module runs at DDR5 5600 (PC5-44800) with a CAS latency of 46 and operates at 1.1V. A single stick delivers 128GB, so maximum system memory depends on the number of slots the server provides. Workloads exceeding that total will need additional DIMMs or a platform with more channels.

288-pin registered design without heat spreader

The 4Rx4 registered layout adds a buffer that stabilises signals in dense configurations, but it cannot be mixed with unbuffered or load-reduced ECC memory. JEDEC and RoHS compliance ensures a warranty-safe upgrade. The bare PCB fits standard 288-pin DDR5 slots, leaving cooling to the chassis airflow.

Perguntas sobre este artigo

Will this 5600 CL46 4Rx4 module run with existing DDR5 4800 RDIMMs in my Supermicro SSG-121E?

The module follows JEDEC DDR5 5600 specifications. The server will clock all installed DIMMs to the lowest common speed, so 4800 RDIMMs will operate at 4800 MT/s.

How can I verify the 128GB 4Rx4 ECC registered module is detected correctly after installation?

Check the BIOS memory map or run `dmidecode -t memory` on Linux; you should see one 128GB DIMM at 5600 MT/s, CL46, 1.1V, registered, ECC enabled.

Does the single 128GB 288-pin RDIMM ship with a heat spreader or any extra accessories?

The module has no heat spreader and no extra accessories are included; only the DIMM itself is in the box.
