System-specific server kit

This 1 TB kit contains eight 128 GB DDR5 RDIMMs built for the Supermicro GPU SuperServer SYS-422GS-NBRT-LCC. Each module is registered with ECC and a 2Rx4 organisation, providing the error correction and signal integrity required by that platform.

Registered DDR5 for dense configurations

The modules operate at 1.10 V and fit 288-pin DDR5 slots, leaving no need for unbuffered or non-ECC alternatives. Because they are registered, the memory controller sees a reduced electrical load, allowing the full eight-module population without additional buffering hardware.

Sustained throughput at CL52

Rated at 6400 MHz with a CAS latency of 52, the kit delivers consistent bandwidth under continuous server workloads rather than brief bursts. The major-brand DRAM chips and registered design maintain stability during extended compute or virtualisation tasks.

Questions about this item

Will the CL52 latency become the bottleneck when the server runs sustained workloads?

CL52 is the rated CAS latency for these DDR5 modules; sustained throughput will depend on the Supermicro SYS-422GS-NBRT-LCC memory controller and workload pattern.

How much heat and power should I expect from the 8-module kit running continuously?

Each 128 GB RDIMM operates at 1.1 V with no heat spreader; total kit power scales with all eight modules active, and airflow across the 288-pin slots is the primary cooling path.

What motherboard feature must my Supermicro system already provide for this registered ECC kit to function?

The SYS-422GS-NBRT-LCC must support DDR5 288-pin RDIMM slots with registered ECC capability and a memory controller qualified for 6400 MT/s 2Rx4 modules.
