OWC 64GB DDR5 4800 CL40 ECC Registered RDIMM memory upgrade

SKU CH-7Y1B-7YDBJ

A 64 GB DDR5 ECC registered RDIMM running at 4800 MT/s with CL40 latency for compatible Gigabyte workstation and server boards

  • Total capacity64 GB
  • Rated speedDDR5 4800 (PC5 38400)
  • CAS latency40
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • Memory rank2Rx4

Capacity 64GB

  • ECC registered design protects data integrity in servers
  • 64GB single module expands memory capacity efficiently
  • DDR5 4800 speed with CL40 latency delivers responsive performance
  • 1V operation reduces power draw for dense deployments
  • Validated for Gigabyte R183-ZF0, R183-ZF1, R263-Z30, R263-Z32, R263-Z33

Target server upgrade

This 64GB DDR5 4800 CL40 ECC Registered RDIMM is built for Gigabyte R183-ZF0, R183-ZF1, R263-Z30, R263-Z32 and R263-Z33 servers and workstations. It delivers 64GB in a single 288-pin module running at 1.1V with a 2Rx4 organisation. The part is validated for workloads that require error-correcting registered memory.

Compatibility checklist

Confirm the target system is one of the five Gigabyte models listed. Verify the motherboard has free 288-pin DDR5 RDIMM slots and that the BIOS supports registered ECC modules. Do not mix this stick with unbuffered or load-reduced ECC memory. The module has no heat spreader, so check airflow in dense chassis.

Replaces lower-capacity RDIMMs

Swapping smaller registered ECC DIMMs for this 64GB module increases total memory without occupying extra slots. The jump is worthwhile when virtualisation, large databases or NAS workloads exceed the current capacity and the platform accepts 2Rx4 DDR5 4800 registered memory.

Questions about this item

Does the module include any mounting hardware or do I need to buy a heatsink separately?

The 288-pin DDR5 RDIMM ships as a single 64 GB stick without a heat spreader; no extra brackets or cooling parts are required for installation in the listed Gigabyte servers.

Should I choose a different capacity or rank configuration for my Gigabyte R263-Z32?

This kit provides one 64 GB 2Rx4 registered DIMM; add identical modules to fill the remaining slots for maximum bandwidth on the R263-Z32 platform.

Will the CL40 latency at 4800 MT/s slow down my database workload on an R183-ZF1?

At DDR5 4800 CL40 the module delivers 38 400 MB/s peak bandwidth with ECC error correction, matching the JEDEC spec the R183-ZF1 expects for stable database throughput.
