768GB DDR5 ECC RDIMM kit

This NEMIX RAM kit provides 768GB of DDR5 memory across twelve 64GB registered DIMMs. It is designed for server and workstation platforms that require error-correcting code and registered buffering. The modules operate at 6400MHz with a CAS latency of CL52 and a voltage of 1.1V. This capacity targets memory-intensive workloads such as virtualization, large databases and GPU compute.

Check DDR5 RDIMM slot count and CPU support

Verify that your motherboard has twelve available 288-pin DDR5 RDIMM slots and that the processor supports 2Rx4 registered modules at this density. Confirm the platform can run memory at 6400MHz with CL52 timings at 1.1V. Consult the system manual for approved population rules and maximum supported capacity per channel before ordering.

Suits Supermicro AS-8126GS-NB3RT GPU servers

This kit is validated for the Supermicro GPU A+ Server AS-8126GS-NB3RT and similar platforms that accept twelve 64GB DDR5 RDIMMs. It is not suitable for consumer desktops, laptops or workstations that use unbuffered UDIMMs or SO-DIMMs. Buyers needing non-ECC memory, lower capacities or different form factors should select an alternative product.

Questions about this item

Does the kit include all 12 modules or do I need to buy extra sticks?

The kit contains twelve 64 GB modules for a total of 768 GB, so no additional sticks are required.

Should I choose the 768 GB 12x64 GB kit or a smaller capacity for the Supermicro AS-8126GS-NB3RT?

Select the 768 GB kit if the server has twelve free DDR5 RDIMM slots and the workload needs maximum registered ECC capacity; otherwise a smaller kit leaves room for future expansion.

What does the 6400 MHz rating mean once the memory is installed in the server?

The modules run at 6400 MT/s with CL52 latency at 1.10 V, delivering the rated PC5-51200 bandwidth when the platform trains them at that speed.
