  • 256 GB total capacity from four matched 64 GB modules
  • DDR5 6400 speed with CL52 latency for rated server performance
  • Registered ECC design corrects single-bit errors to protect data integrity
  • 10 V low voltage reduces power draw in fully populated systems
  • Verified fit for Gigabyte MZ73-LM2 with 288-pin RDIMM form factor

Targeted Server Upgrade

This 256 GB kit delivers four 64 GB DDR5 RDIMM modules rated at 6400 MT/s with CL52 latency. Registered ECC architecture and 1.1 V operation match the GIGABYTE MZ73-LM2 motherboard requirements exactly, so the memory controller recognises full capacity at rated speed without manual tuning.

Sustained Workload Behaviour

Registered buffering reduces electrical load on the memory controller, allowing all four slots to remain fully populated at 6400 MT/s during continuous operation. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during long compute runs or virtualisation tasks.

Build and Connectors

Modules use a bare 288-pin PCB without heat spreaders, relying on server chassis airflow for cooling. The RDIMM keying ensures installation only in compatible registered DIMM slots, while the 2Rx4 organisation aligns with the board's population rules for stable operation across all channels.

Perguntas sobre este artigo

How much heat and power should I expect from the 256GB DDR5 6400 CL52 kit running continuously?

Each 64GB module operates at 1.1V with no heat spreader, so power draw per stick is low and airflow across the 288-pin RDIMM slots is the main cooling requirement.

What motherboard and slot configuration must I already have for this 4x64GB registered ECC kit to work?

The kit is verified for the GIGABYTE MZ73-LM2 motherboard and requires four DDR5 288-pin RDIMM slots populated in the board's approved population order.

Can I mix these 2Rx4 DDR5 6400 registered ECC modules with other DDR5 RDIMMs of different rank or speed in the same server?

Mixing ranks or speeds is not recommended; the motherboard's memory controller expects identical 2Rx4 modules at DDR5 6400 to run all slots at rated capacity and timing.
