Exact-match DDR5 RDIMM kit for GIGABYTE MZ33-CP1

This 128GB kit contains two 64GB DDR5 4800 RDIMMs built to the precise 2Rx4 1.1V CL40 specification the GIGABYTE MZ33-CP1 memory controller expects. Registered ECC architecture delivers full-capacity recognition and single-bit error correction for production workloads.

Verify motherboard population rules

Consult the GIGABYTE MZ33-CP1 manual for approved DIMM population order, maximum capacity per slot, and installation steps before ordering. Registered RDIMMs are required; UDIMM or SODIMM modules will not fit or function on this platform.

Registered ECC modules without heat spreaders

The 288-pin RDIMMs use major OEM Samsung, Micron or Hynix chips and omit heat spreaders to suit dense server chassis airflow. Registered buffering reduces electrical load on the memory controller when all slots are populated, while on-die ECC corrects errors in real time.

Questions about this item

What comes in the 128GB kit and do I need any extra parts to install it in a GIGABYTE MZ33-CP1?

The kit contains two 64GB DDR5 4800 CL40 1.1V 2Rx4 ECC Registered RDIMMs in a matched 128GB set. No additional components are required for installation in the MZ33-CP1 motherboard.

Should I choose this 2x64GB 4800 CL40 kit or a different capacity or speed for the MZ33-CP1?

This 128GB 2x64GB DDR5-4800 CL40 kit matches the motherboard's validated speed, voltage, rank and ECC registered format. Other capacities or speeds may not be supported or could run at reduced performance.

What does the DDR5-4800 CL40 rating mean once the modules are running in the server?

The modules operate at 4800 MT/s with a CAS latency of 40 cycles at 1.1V. The registered buffer and ECC let the memory controller drive all slots at full rated speed while correcting single-bit errors automatically.
