Server DDR5 ECC RDIMM kit

This NEMIX RAM kit provides 1TB of DDR5 memory across eight 128GB registered DIMMs. It runs at 6400MHz with CL52 latency and operates at 1.1V. The modules are designed for Supermicro GPU A+ Server AS-8126GS-NB3RT systems.

Verify motherboard slots and population rules

Confirm your server has eight free 288-pin DDR5 RDIMM slots and supports 2Rx4 registered modules at 6400MHz. Check the system manual for maximum capacity per channel and any required population order before installing this kit.

Suited for high-capacity Supermicro servers

This kit suits administrators expanding memory in the named Supermicro GPU A+ platform. It is not for desktop PCs, laptops or workstations that use unbuffered UDIMMs or a different DDR generation. Buyers needing lower capacities or non-ECC memory should look elsewhere.

Questions about this item

What does the 1TB kit contain and is anything else required for installation?

The kit includes eight 128GB DDR5 6400MHz CL52 2Rx4 1.1V 288-pin ECC RDIMM modules. No additional parts are needed; install them into the server's DIMM slots following the system manual.

Why choose this 1TB (8 x 128GB) DDR5 6400MHz CL52 kit over other capacities?

This configuration delivers 1TB total capacity across eight registered ECC modules at 6400MHz with CL52 latency, matching the Supermicro AS-8126GS-NB3RT's supported memory specification for maximum density.

What does the 6400MHz rating mean when the modules are running in the Supermicro AS-8126GS-NB3RT?

The modules operate at 6400MHz (PC5-51200) with CL52 timings at 1.1V, providing the rated throughput and error-correcting registered performance validated for that server platform.
