Server-grade DDR5 ECC RDIMM

This 64GB DDR5 4800 CL40 registered DIMM delivers error-correcting memory for Gigabyte R283-Z96, R283-Z97, R283-ZF0, R283-ZF1 and S453-Z30 platforms. It operates at 1.1V with a 2Rx4 organisation and conforms to JEDEC PC5-38400 specifications. The module is built for workstations, servers, NAS systems and network switches that require registered ECC memory.

Registered ECC fit and constraints

The 288-pin RDIMM installs in DDR5 RDIMM slots on the listed Gigabyte boards and cannot be mixed with unbuffered or load-reduced ECC modules. Registered buffering reduces electrical load on the memory controller, allowing higher total capacity per channel when the platform supports it. No heat spreader is fitted, so airflow across the module must be provided by the chassis.

Upgrade from lower-capacity RDIMMs

Replacing smaller DDR5 RDIMMs with this 64GB module increases memory density per slot, useful when all slots are populated or when the application demands more addressable memory. The jump is worth it when workloads exceed the capacity of existing modules and the platform qualifies 64GB 2Rx4 registered DIMMs at 4800 MT/s.

Questions about this item

What is the CAS latency limit that appears first when the DDR5 4800 module runs under sustained load?

The module operates at CL40 latency, which is the timing spec that governs response speed during continuous server or workstation workloads.

How much heat and power does the 1.1V registered DDR5 DIMM produce when running all day in a Gigabyte R283-Z96?

At 1.1V with no heat spreader, the registered DDR5 4800 module draws minimal power and runs cool enough for continuous server operation.

Which Gigabyte server motherboards must I already own for this 2Rx4 ECC RDIMM to function?

This 64GB DDR5 4800 CL40 module is validated for Gigabyte R283-Z96, R283-Z97, R283-ZF0, R283-ZF1 and S453-Z30 platforms.
