  • 32 GB DDR5-4800 ECC RDIMM ensures full-capacity operation on GIGABYTE MZ33-CP1
  • Registered 2Rx8 design offloads the memory controller for stable fully-populated slots
  • ECC corrects single-bit errors on the fly to prevent silent data corruption
  • 10 V CL40 timing matches the board's exact voltage and latency requirements
  • 288-pin RDIMM form factor fits the server motherboard's DIMM slots precisely

Purpose-built server upgrade

This 32 GB DDR5 module is an exact-match upgrade for the GIGABYTE MZ33-CP1 motherboard. It delivers registered ECC memory at 4800 MT/s with CL40 latency and 1.1 V operation, ensuring full-capacity recognition and rated-speed stability in compatible systems.

DDR5 RDIMM limits

The DDR5 4800 standard used here tops out at 38400 MB/s peak bandwidth per module, and the registered buffer adds a cycle of latency to every command. Population rules on the MZ33-CP1 restrict which slots can be filled together, so maximum capacity depends on the board's approved DIMM sequence rather than the module itself.

Build and daily fit

The 288-pin RDIMM form factor keys only into registered DIMM slots, preventing accidental insertion into consumer UDIMM or SODIMM sockets. Samsung, Micron or Hynix DRAM chips are used without a heat spreader, relying on chassis airflow for cooling in densely populated server configurations.

Questions about this item

Should I pick the 32GB 2Rx8 DDR5-4800 kit or a different capacity for my GIGABYTE MZ33-CP1?

This kit provides exactly 32GB in a single 2Rx8 registered ECC module at 4800 MT/s CL40 1.1V. Choose it when your board's qualified-vendor list calls for that rank and voltage; other capacities or ranks may not populate correctly.

What does the 4800 MT/s rating actually deliver once the module is installed in the server?

The memory controller will initialise the DIMM at DDR5-4800 with CL40 timings at 1.1V, giving the rated PC5-38400 bandwidth. Registered buffering lets every slot run at that speed even when fully populated.

How does the 288-pin RDIMM interface and registered ECC design limit or enable real-world use?

The 288-pin RDIMM form factor fits only DDR5 registered DIMM slots. Registered architecture reduces electrical load on the controller, while ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads.
