128GB DDR5 ECC RDIMM Kit

This NEMIX RAM kit delivers 128GB of registered DDR5 memory across two 64GB modules. It operates at 6400MHz with CL52 latency and a 1.1V voltage. The 2Rx4 organisation and ECC support target server and workstation workloads requiring data integrity.

Upgrade from non-ECC or lower-capacity DDR5

The jump is worth it when your Supermicro AS-8126GS-NB3RT needs registered DIMMs with error correction for stability. It replaces unbuffered or consumer-grade memory that the platform cannot use. The 128GB capacity suits virtualisation or large datasets exceeding smaller kits.

Fits Supermicro GPU A+ Server AS-8126GS-NB3RT

The 288-pin RDIMM form factor slots directly into the server's memory channels. Registered signalling reduces electrical load on the memory controller. No heat spreader is fitted, so airflow across the modules must be managed by the chassis.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the Supermicro AS-8126GS-NB3RT server slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the memory slots on the Supermicro AS-8126GS-NB3RT.

What is the correct order to install the two 64GB modules in the AS-8126GS-NB3RT?

Populate the channels indicated in the server manual, typically starting with the first slot of each channel, and seat each module until the latches click.

When should the ECC RDIMM kit be replaced in a production server?

Replace modules if the system logs correctable ECC errors that increase over time or if the server fails memory diagnostics during scheduled maintenance.
