NEMIX RAM 768GB DDR5 kit for Supermicro

This registered ECC RDIMM kit delivers 768GB across eight 96GB modules. It targets administrators expanding memory in the specified Supermicro GPU A+ server. The modules operate at 6400MHz with a CL52 latency and 1.1V supply. Buyers who need non-ECC or unbuffered DIMMs for workstation boards should look elsewhere.

Registered ECC DDR5 at 6400MHz with CL52

The single specification that determines fit is the registered ECC DDR5 RDIMM interface running at 6400MHz PC5-51200 with CL52 timing. The 2Rx4 organisation and 1.10V voltage must match the server memory controller. Systems requiring load-reduced or unregistered modules will not accept this kit.

Eight 288-pin modules fill the server memory slots

The kit occupies eight DDR5 RDIMM slots in the compatible Supermicro platform. Each 96GB module uses a 288-pin connector without a heat spreader. The registered buffer reduces electrical load on the memory controller, freeing signal integrity headroom for the full 768GB population. Ensure the BIOS revision supports this density before installation.

Questions about this item

How does the 6400 MHz speed translate to real bandwidth inside the AS-8126GS-NB3RT?

The DDR5 6400 MT/s rating delivers up to 51200 MB/s of peak bandwidth per module when the server runs at the rated data rate.

What does the PC5-51200 designation limit in practice?

PC5-51200 confirms the 51200 MB/s ceiling; the memory controller cannot exceed that throughput without overclocking.

Will the 288-pin RDIMM modules fit the AS-8126GS-NB3RT memory slots?

Yes, the kit uses standard 288-pin DDR5 RDIMM form factor designed for the Supermicro AS-8126GS-NB3RT DIMM sockets.
