Server-grade DDR5 memory kit

This 512GB kit contains four 128GB DDR5 5600MHz RDIMMs built for the GIGABYTE MZ73-LM0 motherboard. Registered ECC architecture and CL46 timing match the board's memory controller requirements exactly. The modules operate at 1.1V and use major OEM chips from Samsung, Micron or Hynix.

Capacity and headroom

Four populated slots deliver 512GB of registered ECC memory for virtualisation, databases and large dataset workloads. The 2Rx4 organisation allows full-capacity operation across all channels at the rated 5600MHz speed. Headroom ends when the platform's maximum supported DIMM count or total capacity is reached.

Build quality and daily implications

Registered buffering reduces electrical load on the memory controller for stable operation with all slots filled. ECC corrects single-bit errors automatically to prevent silent data corruption. The 288-pin RDIMM form factor fits only compatible DDR5 server sockets and lacks a heat spreader for dense rack environments.

Questions about this item

Can I add this 288-pin RDIMM kit alongside the existing DDR5 modules already installed in my GIGABYTE MZ73-LM0?

The board requires registered ECC DDR5 at 1.1V; mixing ranks or speeds may force a lower common speed, so populate all four slots with this matched 512 GB kit for guaranteed operation.

How do I confirm the kit is running at DDR5 5600 with CL46 after installation?

Enter the firmware or use a system information tool and verify the memory speed reads 5600 MT/s, CAS latency shows 46, voltage reads 1.10 V and ECC status reports active.

What exactly ships in the box and is anything else required to install it?

The package contains four 128 GB DDR5 5600 CL46 2Rx4 1.1 V 288-pin ECC RDIMM modules; no extra cables, brackets or heat spreaders are needed or included.
