OWC 64GB DDR5 5600 CL46 2Rx4 288-pin 1.1V ECC RDIMM for Supermicro X13DEG-PVC QT R DEH DEI memory upgrade

SKU CH-0EJC-TTCCE

Adds 64GB DDR5 5600 ECC registered memory to compatible Supermicro X13DEG series motherboards

  • Total capacity64 GB
  • Rated speedDDR5 5600 (PC5 44800)
  • CAS latency46
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • Memory rank2Rx4

Capacity 64GB

  • Server-grade ECC protects data integrity in critical workloads
  • 64 GB single module expands capacity without extra slots
  • DDR5 5600 speed matches platform spec for stable throughput
  • 1 V operation lowers power draw versus higher-voltage alternatives
  • Validated for Supermicro X13DEG series motherboards

Single 64GB DDR5 ECC RDIMM

This OWC module delivers 64GB of DDR5 5600 registered ECC memory in a single 288-pin DIMM. It operates at 1.1V with CL46 latency and a 2Rx4 organisation. The part is validated for Supermicro X13DEG-PVC, X13DEG-QT, X13DEG-R, X13DEH and X13DEI motherboards.

Suited for registered-ECC platforms only

The module is built for workstations, servers, NAS systems and network switches that require registered ECC DDR5. It will not work in standard desktop computers and cannot be mixed with unbuffered or load-reduced ECC DIMMs. Buyers needing non-ECC or unbuffered memory should look elsewhere.

Fits Supermicro X13DEG series boards

Install the DIMM into a compatible 288-pin DDR5 slot on the listed Supermicro motherboards. The registered buffer reduces electrical load on the memory controller, freeing the platform to populate more slots per channel. Ensure the system firmware supports the 5600 MT/s data rate.

Questions about this item

Which Supermicro motherboards will accept this OWC 64GB DDR5 5600 ECC RDIMM?

This module is validated for the Supermicro X13DEG-PVC, X13DEG-QT, X13DEG-R, X13DEH and X13DEI boards.

Can I mix this registered ECC RDIMM with unbuffered or load-reduced DIMMs already in my server?

No — the manufacturer states it cannot be mixed with unbuffered or ECC load-reduced memory.

How do I confirm the DIMM is running at 5600 MT/s with CL46 timings after installation?

Check the BIOS memory information screen or use a tool such as dmidecode to verify speed and latency.
