OWC 64GB DDR5 4800 ECC RDIMM

This 64GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.1V operation. It uses a 2Rx4 registered ECC design built for Gigabyte R283-Z91 through R283-Z95 platforms. The 288-pin RDIMM targets workstations, servers and NAS systems that require registered memory. It will not fit standard desktop boards or mix with unbuffered or load-reduced DIMMs.

Sustained load behaviour

Registered buffering and on-die ECC maintain data integrity during continuous server workloads. The 1.1V JEDEC voltage keeps power draw predictable across fully populated channels. CL40 timing is optimised for stability at the 4800 speed rating rather than low-latency bursts. Thermal performance relies on system airflow as the module has no heat spreader.

Upgrade context

A single 64GB stick replaces lower-capacity registered ECC DDR5 modules in compatible Gigabyte R283-Z9x systems. The jump is worthwhile when expanding total memory for virtualisation, large datasets or multi-user NAS services. It does not suit builds needing unbuffered memory, non-ECC operation or higher-speed DDR5 beyond the 4800 JEDEC baseline.

Pontos fortes

  • 64 GB capacity supports large workloads in compatible servers
  • DDR5 4800 speed with CL40 latency for responsive data handling
  • ECC registered design detects and corrects memory errors automatically
  • 1 V operation reduces power draw in Gigabyte R283-Z91 through R283-Z95 systems
  • JEDEC and RoHS compliant module ensures warranty-safe upgrade path
