Exact-match server upgrade

This kit delivers 384GB of DDR5 memory across six 64GB registered ECC RDIMMs. It is built for administrators expanding a GIGABYTE MZ33-CP1 motherboard to its full supported capacity with modules the memory controller recognises immediately.

Registered ECC architecture

The 2Rx4 registered design buffers address and command signals so every slot stays stable when fully populated. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption that could otherwise halt production workloads.

288-pin RDIMM form factor

Modules use the standard 288-pin DDR5 RDIMM connector required by the target board, not UDIMM or SODIMM layouts. A 1.10V operating voltage matches the platform specification, while the lack of heat spreaders keeps the profile low for dense multi-socket chassis.

Questions about this item

Will the 2Rx4 ECC RDIMM modules need any firmware updates or re-seating over their lifetime?

No firmware updates or routine re-seating are required for these 2Rx4 registered ECC DDR5 modules; they are validated for the GIGABYTE MZ33-CP1 and run at 1.1 V with CL40 timing for the life of the server.

What limit appears first when all six slots run DDR5-4800 continuously at full 384 GB capacity?

The registered 2Rx4 architecture offloads the memory controller so the first practical limit is the motherboard's maximum supported capacity, not signal integrity or thermal throttling on the DIMMs themselves.

How much heat and power do the six 64 GB sticks draw at 1.1 V under 24/7 load?

Each module operates at 1.1 V with no heat spreader; total kit power stays within standard DDR5-4800 RDIMM limits, and the registered design keeps per-slot current low for continuous operation.
