OWC 64GB DDR5 5600 ECC RDIMM 2Rx4 CL46 1.1V Gigabyte R183-S90/91/92/93/94 memory upgrade

SKU CH-5676-FP6N3

A 64GB DDR5 5600 ECC registered RDIMM for Gigabyte R183-S90, R183-S91, R183-S92, R183-S93 and R183-S94 servers

  • Capacity64GB
  • Type288-Pin DDR5 ECC RDIMM
  • SpeedDDR5 5600 (PC5 44800)
  • CAS Latency46
  • Voltage1.1V
  • ECCYes

Capacity 64GB

  • 64 GB single module doubles server memory capacity
  • DDR5 5600 speed handles heavy workloads with high bandwidth
  • ECC registered design protects data integrity in critical tasks
  • 1 V operation reduces power draw and heat output
  • Validated for Gigabyte R183-S90 through R183-S94 systems

Target system and purpose

This 64GB DDR5 ECC RDIMM is built for Gigabyte R183-S90, R183-S91, R183-S92, R183-S93 and R183-S94 servers and workstations. It adds a single registered module to systems that require error-correcting memory for data integrity. The module will not function in standard desktop computers or in platforms that accept only unbuffered or load-reduced DIMMs.

Interface and registration limits

The DDR5 5600 interface runs at 1.1V with a CAS latency of 46 and a 2Rx4 organisation. JEDEC compliance guarantees electrical compatibility, but the registered buffer and ECC logic mean the memory must be installed in slots wired for registered DIMMs. Mixing this module with unbuffered or load-reduced memory is not supported and will prevent boot.

Deciding specification

The registered ECC design is the single factor that determines whether this part fits the build. Only systems listed in the compatibility list that explicitly call for 288-pin DDR5 ECC RDIMMs can use this upgrade. Buyers whose hardware requires unbuffered or load-reduced modules cannot use this product.

Questions about this item

Should I choose a single 64GB module or multiple smaller modules for my Gigabyte R183-S90?

This listing is a single 64GB DDR5 5600 ECC Registered RDIMM; add more identical modules to reach your desired total capacity.

What does the 5600 speed rating mean once the module is installed in a Gigabyte R183-S92?

The module runs at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V, delivering the rated throughput when the platform enables that speed.

Is the 288-pin DDR5 interface compatible with standard desktop motherboards?

No — this is an ECC Registered RDIMM for workstations and servers such as the Gigabyte R183-S90 through R183-S94 and will not work in standard desktop boards.
