Capacity and Configuration

This kit provides 384GB of DDR5 memory across four 96GB registered DIMMs. It is designed for the SuperMicro GPU SuperServer SYS-422GS-NBRT-LCC and similar enterprise platforms that require high-density ECC modules.

DDR5 Registered ECC Limits

Registered DIMMs add a buffer that reduces electrical load on the memory controller, allowing larger capacities per channel. The modules run at 6400MHz with a CAS latency of 52 and operate at 1.1V. Systems must support DDR5 RDIMM topology and the 2Rx4 organisation to use this kit.

Pre-Installation Checks

Verify that the motherboard firmware accepts 96GB 2Rx4 registered modules and that the CPU memory controller can address the total 384GB capacity. Confirm the server has four available 288-pin DDR5 slots and that the platform qualifies this part number for the target workload.

Questions about this item

Should I choose the 384GB kit or look for a smaller capacity?

The kit contains four 96GB modules for a total of 384GB. Select this capacity if your SuperMicro SYS-422GS-NBRT-LCC has enough 288-pin DDR5 slots and your workload needs that much registered ECC memory.

What does the 6400MHz rating mean once the modules are installed in the SuperServer?

The modules run at 6400 MT/s with CL52 latency at 1.1V. Actual throughput depends on the server's memory controller and how many DIMM slots are populated.

Does the DDR5 RDIMM interface limit the speed or capacity I can use in this server?

The 288-pin DDR5 RDIMM form factor and registered ECC design match the SYS-422GS-NBRT-LCC requirements. The platform's memory controller determines the maximum supported frequency and total capacity.
