128GB DDR5 ECC RDIMM for Supermicro SYS-822GS-NB3RT

This 128GB registered DDR5 module targets administrators expanding memory in Supermicro SYS-822GS-NB3RT servers. It delivers ECC protection and registered signalling for stable operation in multi-socket configurations. The single-module kit suits upgrades where density per slot is the priority. Buyers needing non-ECC or unbuffered memory for consumer platforms should look elsewhere.

Capacity and headroom at 6400MHz CL52

The module runs at 6400MHz with CAS latency 52 and 1.1V voltage, providing 128GB in a 2Rx4 organisation. This density suits virtualisation hosts, in-memory databases and large container fleets that benefit from maximum capacity per channel. Workloads requiring higher frequencies or lower latencies than the rated 6400MHz CL52 will not be satisfied by this specification.

Thermals noise and power at 1.1V

Operating at 1.1V without a heat spreader, the RDIMM relies on server chassis airflow for cooling. Registered buffering and ECC logic add minimal overhead to the base DDR5 power envelope. Systems with restricted airflow or dense DIMM populations must verify that case cooling meets the module's thermal requirements. No active cooling or acoustic profile is specified for this component.

Questions about this item

Will this DDR5 6400MHz CL52 RDIMM run alongside my existing DDR5 modules at the same speed and voltage?

The module operates at 1.1V with CL52 timing at 6400MHz; mixing with other DDR5 RDIMMs will work only if they share the same voltage, speed and CAS latency.

How can I confirm the ECC RDIMM is detected and running at 6400MHz after installation in my SYS-822GS-NB3RT?

Check the BIOS memory information or use a tool such as dmidecode to verify 128GB capacity, 6400MHz speed, ECC enabled and registered mode.

Does the package include only the 128GB DDR5 6400MHz CL52 2Rx4 RDIMM or are extra parts supplied?

The box contains one 128GB DDR5 6400MHz PC5-51200 2Rx4 1.1V CL52 288-pin ECC RDIMM; no additional components are included.
