Exact-fit server upgrade

This NEMIX RAM kit delivers 64GB of DDR5 memory as four 16GB registered ECC RDIMMs. It is built for the GIGABYTE MZ33-CP1 motherboard and matches the board's required 288-pin form factor, 1.10V voltage and CL40 timing so the system recognises full capacity at the rated 4800 MT/s speed.

Replaces mixed or partial kits

Installing this matched 4x16GB set removes the instability that comes from populating slots with different ranks, voltages or speeds. The jump is worth it when a server currently runs with fewer modules, mismatched DIMMs or unbuffered memory that the board cannot support in a fully populated configuration.

Capacity and headroom

The 64GB total handles typical virtualisation workloads, database caching and multi-tenant containers with room for simultaneous VMs. It runs out when workloads demand more memory per socket than the board's maximum supported capacity or when applications need faster data rates than the 4800 MT/s specification provides.

Questions about this item

Will the 288-pin RDIMM modules fit the GIGABYTE MZ33-CP1 motherboard slots?

Yes, the kit uses 288-pin DDR5 RDIMM form factor which matches the MZ33-CP1 memory slots exactly.

What is the correct population order when installing all four 16GB modules?

Consult the MZ33-CP1 manual for the approved DIMM population sequence; the board requires specific slot filling order for full 64GB recognition.

Do these registered ECC modules require any firmware updates or periodic maintenance?

No firmware updates are needed; ECC error correction runs automatically on the memory controller during normal operation.
