Exact-Match DDR5 Server Upgrade

This 128 GB kit delivers two 64 GB DDR5 RDIMMs built for the GIGABYTE MZ73-LM2 motherboard. Registered ECC design meets the board's population rules so every slot runs at its rated 4800 MT/s without manual tuning. It targets administrators who need guaranteed recognition at full capacity.

Capacity and Headroom

Dual-rank 2Rx4 organisation lets the memory controller address the full 128 GB across both modules at 1.1 V. CL40 latency and PC5-38400 bandwidth suit virtualisation hosts and database nodes that scale horizontally. Workloads demanding higher per-thread bandwidth or lower latency will saturate this kit first.

Registered ECC Over Unbuffered

The RDIMM form factor replaces standard UDIMMs that lack buffering and error correction. Registered architecture offloads the controller so all slots stay stable when fully populated, while ECC corrects single-bit errors before they reach production. Builders needing consumer UDIMM pin-outs or non-ECC operation cannot use this kit.

Questions about this item

Will the 2Rx4 registered ECC DDR5-4800 modules run at full speed alongside existing DDR5-4800 RDIMMs in my Gigabyte MZ73-LM2?

Yes, this kit matches the board's DDR5-4800 PC5-38400 spec, 1.1V voltage, CL40 timing and 2Rx4 registered ECC layout, so fully populated slots will operate at rated speed.

How can I confirm the 128 GB kit is recognised at full capacity and running at DDR5-4800 CL40 after installation?

Check the BIOS memory information screen — it should show 128 GB total, DDR5-4800 (PC5-38400) frequency, CL40 latency and ECC registered status for each 64 GB module.

Does the package contain only the two 64 GB RDIMMs or are any cables, brackets or tools included?

The box contains only the two 64 GB DDR5-4800 CL40 2Rx4 ECC registered RDIMMs; no cables, brackets or tools are supplied.
