  • 128 GB capacity in a 4 × 32 GB kit for full server memory population
  • DDR5 5600 speed with CL46 latency for rated performance on compatible boards
  • Registered ECC architecture offloads the controller and corrects single-bit errors automatically
  • 1 V operation matches the motherboard's voltage requirement for stable operation
  • 288-pin RDIMM form factor fits the GIGABYTE MZ33-CP1 memory slots exactly

Exact-match upgrade kit

This 128GB kit contains four 32GB DDR5 5600 registered ECC RDIMMs built to the precise rank, voltage and timing the GIGABYTE MZ33-CP1 memory controller expects so the server recognises full capacity and runs at rated speed. It is intended for administrators upgrading that specific motherboard with a validated 2Rx8 1.1V configuration.

2Rx8 registered ECC at 1.1V

The single specification that decides fitment is the 2Rx8 registered ECC organisation combined with 1.1V CL46 timing on a 288-pin DDR5 RDIMM because the MZ33-CP1 requires exactly that electrical and mechanical profile and will not accept UDIMM SODIMM or different rank layouts.

No heat spreader and lifetime support

Modules ship without a heat spreader to maintain standard RDIMM height for dense server chassis while the lifetime replacement warranty and US-based technical support provide long-term service coverage for production environments. Buyers needing UDIMM SODIMM or non-ECC memory should look elsewhere.

Questions about this item

Will this DDR5 5600 kit run at its rated 5600 speed once installed in the GIGABYTE MZ33-CP1?

Yes, the kit is spec-matched to the board's memory controller so all four 32 GB modules are recognised at full capacity and operate at the rated DDR5 5600 speed.

What does the PC5-44800 label mean for real-world bandwidth on this motherboard?

PC5-44800 is the peak transfer rate of DDR5 5600; the registered design lets every slot stay populated at that rate without down-clocking.

Does the 288-pin RDIMM form factor fit the MZ33-CP1 DIMM slots without adapters?

The 288-pin registered DIMM matches the board's native slot keying exactly, so no adapter or converter is needed.
