Exact-match 64GB DDR5 kit for GIGABYTE MZ33-AR1

This 64GB kit contains two 32GB DDR5-4800 Registered ECC RDIMMs built to the precise rank, voltage and timing the GIGABYTE MZ33-AR1 memory controller expects. The modules are 2Rx8, run at 1.1V with CL40 latency and use the 288-pin RDIMM form factor required by this server board.

Install by following the board manual population

The motherboard manual defines the supported capacities, approved DIMM population order and installation steps; consult it before fitting the modules. Registered RDIMMs must be seated fully in the correct slots so the memory controller recognises the full 64GB at rated speed.

DDR5-4800 bandwidth limits total throughput

The DDR5-4800 (PC5-38400) interface caps peak data rate at the rated speed, so sustained throughput cannot exceed this ceiling. Registered buffering and ECC add minor latency overhead while protecting data integrity, and the 1.1V operating voltage is fixed by the DDR5 standard for this speed grade.

Questions about this item

How can I confirm the NEMIX RAM 64GB kit is running at DDR5 4800 CL40 after installation?

Check the BIOS memory information or a tool like CPU-Z to verify the modules report 4800 MT/s, CL40 timings, 1.10 V, and registered ECC operation on the GIGABYTE MZ33-AR1.

What is included in the package and what must be purchased separately?

The box contains the 64 GB kit as two 32 GB 288-pin DDR5 RDIMMs; no heat spreaders, cables, or additional hardware are included.

Which capacity or version of this memory should I choose for the GIGABYTE MZ33-AR1?

This 64 GB (2 x 32 GB) 2Rx8 registered ECC kit matches the board's DDR5 4800 PC5-38400 specification; select it when your configuration calls for a two-DIMM populated channel at full rated speed.
