  • Full 512 GB capacity across eight 64 GB modules for maximum server memory density
  • DDR5-4800 speed with CL40 timing at 1.1 V delivers rated throughput without overclocking
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated channels
  • 288-pin RDIMM form factor matches GIGABYTE MZ73-LM1 slot requirements exactly
  • Built with major OEM DRAM chips for enterprise-grade reliability

Exact-match server kit

This 512 GB kit contains eight 64 GB DDR5-4800 RDIMMs built to the PC5-38400 standard. Registered ECC modules with 2Rx4 organisation and CL40 timing run at 1.1 V and are specified for the GIGABYTE MZ73-LM1 motherboard.

Slot-ready installation

The 288-pin RDIMM form factor matches the board's memory slots exactly; no UDIMM or SODIMM will fit. Populate all eight slots following the motherboard manual's population order so the registered buffer can offload the memory controller and the system recognises the full capacity at rated speed.

Enterprise capacity seekers

Suits administrators who need the maximum validated 512 GB in a single kit with on-the-fly error correction for production workloads. Not for buyers who want consumer UDIMMs, non-ECC modules, lower capacities or speeds other than DDR5-4800.

Questions about this item

How do I verify the kit runs at DDR5-4800 CL40 after installation?

Enter the BIOS or UEFI and confirm the memory speed reads 4800 MT/s with CAS latency 40; the registered ECC design ensures all eight slots operate at rated speed when fully populated.

What ships with the 512GB kit and what must I source separately?

The box contains eight 64 GB DDR5-4800 2Rx4 registered ECC RDIMMs (part MR38400-924K8); no heat spreaders, cables or tools are included.

Which capacity version suits a GIGABYTE MZ73-LM1 build?

This 512 GB (8 × 64 GB) kit matches the board's DDR5-4800 registered ECC RDIMM requirement; consult the motherboard manual for approved population order before choosing a different capacity.
