Server-grade DDR5 ECC RDIMM

This 64GB DDR5 4800 CL40 registered module is built for Gigabyte R263-Z34, R263-Z35, R263-Z36, R263-Z37 and R283-Z90 platforms. It delivers error-correcting, registered performance at 1.1V for workstations, servers and NAS systems that require ECC registered memory.

Suited for qualified Gigabyte servers.

IT administrators upgrading compatible Gigabyte 263-series or 283-Z90 hardware will find a direct-fit, JEDEC-compliant 2Rx4 DIMM. Builders of standard desktop PCs, consumer workstations or any system needing unbuffered or load-reduced memory cannot use this module.

Registered ECC decides compatibility

The single specification that determines fit is the registered ECC RDIMM design; only motherboards that explicitly support registered error-correcting DDR5 at 4800 MT/s with 2Rx4 organisation will accept this 64GB upgrade.

Questions about this item

Will this 64GB DDR5 4800 ECC RDIMM work alongside other registered ECC modules already installed in my Gigabyte R263-Z34 server?

Yes, it is a single 64GB 2Rx4 registered ECC DIMM at 1.1V and must only be paired with other registered ECC modules, not unbuffered or load-reduced types.

How can I verify the module is running at DDR5 4800 CL40 after installing it in a Gigabyte R283-Z90?

Check the BIOS or operating-system memory report; it should show 4800 MT/s, CAS latency 40, 1.1 V and registered ECC mode active.

Does the package include a heat spreader or any extra mounting hardware for the 288-pin RDIMM?

No heat spreader is included; the box contains only the bare 64GB DDR5 4800 CL40 2Rx4 registered ECC DIMM.
