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

This NEMIX RAM module provides a 128GB DDR5 6400MHz registered ECC upgrade for the Supermicro GPU A+ Server AS-8126GS-NB3RT. It operates at 1.1V with a CAS latency of CL52 and uses a 2Rx4 rank configuration. The 288-pin RDIMM is built with major OEM chips from Samsung, Micron or Hynix.

Server administrators expanding registered ECC

This module suits IT professionals scaling memory capacity in the specified Supermicro server for virtualization, GPU compute or database workloads that require error correction. Builders needing non-registered UDIMMs, lower densities or consumer DDR5 speeds should look elsewhere as this is a registered server part.

Single 128GB DDR5 6400MHz RDIMM capacity

The decisive specification is the 128GB density delivered in a single 288-pin registered DIMM running at 6400MHz PC5-51200. This allows maximum capacity per slot in the compatible Supermicro platform without mixing module sizes or ranks.

Questions about this item

Should I choose the single 128GB module or add multiple sticks for the AS-8126GS-NB3RT?

This listing is a single 128GB DDR5 6400MHz CL52 2Rx4 ECC RDIMM. Add identical modules to fill the remaining DIMM slots on the Supermicro AS-8126GS-NB3RT for maximum capacity.

What does the 6400MHz rating deliver once installed in the Supermicro server?

The module runs at 6400 MT/s (PC5-51200) with CL52 latency at 1.1V, providing registered ECC bandwidth for GPU-intensive workloads on the AS-8126GS-NB3RT.

How does the 288-pin DDR5 RDIMM interface limit real-world throughput?

The 288-pin DDR5 RDIMM electrical interface caps transfer rate at 6400 MT/s; the registered buffer adds one cycle but ensures signal integrity across all populated slots.
