  • 2Rx4 288-pin RDIMM form factor fits the motherboard's population rules precisely
  • Built with Samsung, Micron or Hynix chips for enterprise-grade reliability

Targeted Server Upgrade

This 64GB DDR5 4800 ECC Registered RDIMM is built for the GIGABYTE MZ33-CP1 motherboard. It delivers the exact 2Rx4 rank structure, 1.1V operating voltage and CL40 timing the platform expects. System administrators expanding memory capacity in compatible servers will find the module recognised at its full rated speed. Buyers who need unbuffered UDIMMs, SODIMMs or non-ECC memory cannot use this product.

Pre-Installation Checks

Verify the motherboard manual for approved DIMM population order and maximum supported capacity per slot before ordering. The module uses a 288-pin Registered form factor that fits only DDR5 RDIMM slots; it will not seat in UDIMM or SODIMM sockets. Confirm the server chassis allows access to the memory slots and that the BIOS version supports the installed configuration. Systems requiring different voltages, ranks or form factors will not accept this kit.

Build and Connector Implications

The module operates at 1.1V with a registered buffer that reduces electrical load on the memory controller when all slots are populated. ECC circuitry corrects single-bit errors automatically, helping prevent silent data corruption in production workloads. No heat spreader is fitted, so airflow across the DIMMs must be maintained by the server's cooling design. The 288-pin edge connector keys exclusively into DDR5 RDIMM slots, ensuring correct orientation during installation.

Questions about this item

What comes in the 64GB DDR5 4800 kit and is anything else needed for the GIGABYTE MZ33-CP1?

The package contains a single 64GB 288-pin DDR5 4800 RDIMM. No extra cables or brackets are required; the module installs directly into the motherboard's DDR5 RDIMM slots.

Should I choose the 64GB 2Rx4 CL40 module or a different capacity for this board?

This 64GB 2Rx4 CL40 1.1V RDIMM is the exact specification validated for the GIGABYTE MZ33-CP1. Select this part when the manual calls for a 64GB registered ECC DDR5 4800 DIMM.

What does the 4800MHz PC5-38400 rating mean once the module is installed in the server?

The module will run at DDR5 4800 with CL40 latency at 1.1V, delivering the full PC5-38400 bandwidth the memory controller expects when populated according to the board's population rules.
