Capacity and compatibility

This 128GB DDR5 6400 RDIMM kit is built for servers and workstations that require registered ECC memory. The 2Rx4 organisation, 1.1V operation and CL52 timing match the memory controller expectations of the GIGABYTE MA34-CP0 motherboard so the full capacity is recognised at rated speed.

Registered ECC benefit

Registered buffering reduces electrical load on the memory controller allowing every slot to run fully populated at 6400 MT/s. On-die ECC detects and corrects single-bit errors in real time preventing silent data corruption and unplanned reboots in production workloads.

Pre-purchase checklist

Verify the motherboard manual for supported capacities per slot, approved DIMM population order and any BIOS version requirements before ordering. This module uses the 288-pin DDR5 RDIMM form factor and will not fit UDIMM or SODIMM slots.

Questions about this item

Will the 128GB DDR5 6400 CL52 2Rx4 ECC RDIMM modules need firmware updates or scheduled replacement intervals?

No firmware updates or scheduled replacement intervals are required; the modules are solid-state components designed for continuous server operation.

What is the first limit reached when the 128GB DDR5 6400 CL52 2Rx4 ECC RDIMM runs at full load continuously?

The memory controller's maximum supported capacity and population rules for the GIGABYTE MA34-CP0 motherboard determine the practical limit.

How much heat and power does the 128GB DDR5 6400 CL52 2Rx4 ECC RDIMM produce when running all day without a heat spreader?

Operating at 1.10V, the registered ECC RDIMM draws low power per module; without a heat spreader it relies on chassis airflow for cooling.
