System-specific DDR5 RDIMM kit

This NEMIX RAM kit provides 192GB of DDR5 ECC registered memory across twelve 16GB modules. It is built for SuperMicro Storage SuperServer SSG-521E-E1CR24H, SSG-521E-E1CR24L and X13SEDW platforms that require registered DIMMs. The modules run at 4800MT/s with a CL40 latency at 1.10V.

Verify registered DIMM support and slot count

Confirm that your SuperMicro system accepts 288-pin DDR5 RDIMMs and has twelve available memory slots for the full kit. The motherboard must support registered ECC memory at the DDR5 4800 speed grade. Check the system manual for the approved memory population rules before ordering.

Low-voltage registered operation

Each module operates at the standard DDR5 1.10V without a heat spreader, relying on server chassis airflow for cooling. Registered buffering and ECC add minimal latency while maintaining signal integrity across all twelve slots. Power draw scales with the full 192GB capacity under sustained server workloads.

Questions about this item

Does the kit include all 12 modules or must any be purchased separately?

The package contains the full 192GB kit with 12 modules of 16GB each, so nothing else is required to reach the stated capacity.

When should I choose this 192GB 4800 CL40 kit instead of a smaller or faster DDR5 option?

Select this kit when your Supermicro SSG-521E-E1CR24H or SSG-521E-E1CR24L needs the maximum 192GB registered ECC capacity at the platform-native 4800 MT/s speed.

What does the 4800 MT/s rating deliver once the modules are installed in a compatible Supermicro server?

The modules run at the JEDEC-standard DDR5 4800 MT/s data rate with CL40 latency at 1.1 V, providing the baseline registered ECC throughput the X13SEDW platform expects.
