OWC 64GB DDR5 ECC RDIMM for Gigabyte Servers

This 64GB DDR5 4800 CL40 registered DIMM is built for Gigabyte R163-Z30, R163-Z32, R163-Z35, R183-Z90 and R183-Z91 systems. It delivers ECC error correction and registered buffering at 1.1V for stable server and workstation operation.

Who this suits and who should look elsewhere

It fits administrators upgrading or repairing the listed Gigabyte platforms where registered ECC memory is required. Builders of standard desktop PCs or systems needing unbuffered or load-reduced DIMMs cannot use this module.

Installation notes

The 288-pin DDR5 form factor seats like any RDIMM; align the notch and press until the latches click. The most common issue is mixing this registered ECC stick with unbuffered or load-reduced modules, which prevents the system from booting.

Questions about this item

Which Gigabyte servers accept this 64GB DDR5 4800 CL40 ECC Registered RDIMM?

This module is validated for Gigabyte R163-Z30, R163-Z32, R163-Z35, R183-Z90 and R183-Z91 systems.

Can I mix this 2Rx4 registered ECC DIMM with unbuffered or load-reduced memory in the same server?

No. Registered ECC must not be mixed with unbuffered or load-reduced modules; all slots should use the same registered ECC type.

How do I verify the module runs at 4800 MT/s with CL40 after installation?

Check the BIOS or operating system memory report — it should show DDR5-4800 speed and CAS latency 40 for the installed DIMM.
