64 GB DDR5-4800 ECC RDIMM upgrade

This 64 GB DDR5-4800 (PC5-38400) registered ECC module runs at 1.10 V with CL40 timing and a 2Rx4 layout. It fits the 288-pin RDIMM slots required by the GIGABYTE MZ33-AR1 motherboard.

For servers needing registered ECC memory

Suits administrators populating every slot on the MZ33-AR1 with a single, spec-matched 64 GB stick. Not for systems that accept only unbuffered UDIMMs, SODIMM form factors, or non-ECC memory, and not for boards limited to lower capacities per slot.

Single-module kit with lifetime support

The package contains one 64 GB RDIMM; no heat spreader, extra cables or software are included. Lifetime replacement coverage and free US-based technical support are provided by the manufacturer.

Questions about this item

Will this 288-pin DDR5 RDIMM work in my GIGABYTE MZ33-AR1 motherboard?

Yes, the module is verified for the GIGABYTE MZ33-AR1 and matches the board's required 288-pin Registered RDIMM form factor, DDR5-4800 speed, 1.1V voltage, and 2Rx4 rank layout.

Can I mix this 64GB ECC Registered DIMM with unbuffered UDIMMs already installed?

No, Registered RDIMMs and unbuffered UDIMMs use different signalling and cannot be mixed; the memory controller will not initialise a mixed population.

How do I confirm the kit is running at the rated 4800 MT/s and CL40 after installation?

Enter the system BIOS or UEFI and check the memory information screen — it should report DDR5-4800 (PC5-38400), CAS latency 40, 1.1V, and the full 64GB capacity per module.
