Four green DDR4 RDIMM modules with gold contacts and black chips

OWC

OWC 1TB (4x256GB) DDR4 3200 CL22 ECC Registered RDIMM Kit for Cisco UCS C480 M5

SKU CH-RCGM-QQ9RM

A 1 TB DDR4 ECC Registered RDIMM kit of four 256 GB modules running at 3200 MT/s with CL22 latency for the Cisco UCS C480 M5 server

Capacity 1TB (4 x 256GB)

  • ECC registered design protects data integrity in server workloads
  • 1 TB kit (4 × 256 GB) expands Cisco UCS C480 M5 memory capacity
  • DDR4 3200 CL22 timing delivers responsive performance for virtualization
  • 2 V operation reduces power draw in dense configurations
  • Validated against Samsung M393ABG40M52-CAE and Hynix HMAT14JXSRB120N modules

Cisco UCS C480 M5 Memory Kit

This OWC kit supplies four 256 GB DDR4 registered DIMMs for a total of 1 TB. It is built for the Cisco UCS C480 M5 server and will not work in standard desktop computers. The modules are ECC registered and cannot be mixed with unbuffered or load-reduced memory.

Straightforward DIMM Installation

Each module uses the standard 288-pin DDR4 form factor and operates at 1.2 V. Install the four DIMMs into the correct server slots following the system manual. The only common issue is attempting to mix these registered DIMMs with unbuffered or load-reduced types, which the platform does not support.

DDR4 3200 Registered Limits

The kit runs at DDR4 3200 PC4-25600 with CL22 latency and an 8Rx4 octal-rank organisation. Registered ECC memory of this density is limited to platforms that explicitly support 8Rx4 modules and the registered command protocol. Desktop chipsets and consumer motherboards cannot address these DIMMs.

Questions about this item

How can I verify the 3200 MHz DDR4 kit is running correctly after installing the four 256 GB modules in my Cisco UCS C480 M5?

Check the BIOS or server management console to confirm all four DIMMs are detected at 3200 MT/s with ECC registered mode active and CL22 timings applied.

What comes in the box and do I need any extra parts for the Cisco UCS C480 M5?

The kit includes four 256 GB DDR4 3200 CL22 8Rx4 288-pin 1.2 V ECC registered RDIMMs; no additional memory components are required for a full 1 TB installation.

Which capacity should I choose if I want the maximum supported 1 TB configuration for this server?

Select the 1 TB (4 × 256 GB) kit, which populates four slots with matching 256 GB modules for optimal performance and compatibility.
