Kit Composition

This NEMIX RAM kit delivers 384GB of DDR5 capacity across 12 modules of 32GB each. It is built for servers and workstations that require registered ECC memory to maintain data integrity under continuous operation. The 2Rx8 organisation and 1.1V operating voltage match the electrical expectations of compatible Gigabyte platforms.

Sustained Operation

Registered buffering reduces the electrical load on the memory controller, allowing all twelve slots to remain populated at the rated DDR5 4800 speed without down-clocking. ECC circuitry detects and corrects single-bit errors in real time, preventing silent data corruption during long-running workloads. The CL40 latency and 1.10V level are factory-set for stable operation at the specified frequency.

Installation Notes

Each module uses the standard 288-pin RDIMM form factor, which is physically distinct from UDIMM or SODIMM variants and will not seat in the wrong slot type. The motherboard manual for the Gigabyte MZ33-AR1 defines the required population order; deviating from that sequence can prevent the system from recognising the full 384GB. No heat spreaders are fitted, so airflow across the modules must be adequate for the chassis design. Buyers needing a different capacity or a non-registered format should look elsewhere.

Questions about this item

How much power does the 384GB 12x32GB DDR5-4800 CL40 1.1V kit draw when all slots are populated continuously?

Each module operates at 1.10V; total system power depends on the motherboard's memory controller and population rules, so consult the GIGABYTE MZ33-AR1 manual for platform-level figures.

What motherboard feature must the GIGABYTE MZ33-AR1 provide for this 288-pin RDIMM kit to function?

The board must support 288-pin DDR5 Registered ECC RDIMMs with 2Rx8 organisation at DDR5-4800 (PC5-38400) and 1.1V operation across all twelve slots.

Will this 2Rx8 Registered ECC kit work alongside any existing DDR5 RDIMMs already installed in the MZ33-AR1?

Mixed-rank or mixed-speed populations are governed by the motherboard's memory-population rules; check the MZ33-AR1 manual for approved DIMM combinations before adding this kit.
