  • 1V operation reduces power draw
  • Compatible with SuperMicro SYS-121H-TNR and SYS-221H series

Capacity and Compatibility

This kit provides 384GB of DDR5 memory in six 64GB registered ECC modules. It is built for Supermicro Hyper SuperServer systems including the SYS-121H-TNR, SYS-221H-TNR and SYS-221H-TN24R where maximum capacity and error correction are required.

Platform Verification

Confirm that your motherboard accepts 288-pin DDR5 RDIMMs and supports a 2Rx4 organisation at 1.1V. The memory controller must be able to address the full 384GB across all channels and enable ECC functionality in the BIOS.

Build Integration

The modules operate at DDR5 4800 (PC5-38400) with CL40 latency and contain no heat spreaders, so airflow across the DIMM slots must be sufficient. Six slots are consumed, leaving any remaining channels free for further expansion if the platform allows.

Questions about this item

Does the 384GB kit include all six 64GB modules or must they be purchased separately?

The kit contains all six 64GB DDR5 4800 CL40 ECC RDIMM modules in a single package.

Should I choose the 6x64GB 384GB kit or a smaller capacity for my SuperMicro SYS-221H-TNR?

Select the 384GB kit when the workload needs the full 384GB capacity across all six slots; choose a smaller kit if the server has fewer populated channels.

What does the DDR5 4800 PC5-38400 rating mean once installed in a SuperMicro Hyper SuperServer?

The modules run at 4800 MT/s with CL40 latency at 1.10V, delivering the rated PC5-38400 bandwidth in compatible SuperMicro systems.
