Server-grade capacity

This kit delivers 512GB of DDR5 memory across eight 64GB registered DIMMs. It is designed for the Supermicro GrandTwin A+ server AS-2116GT-HNTF and similar platforms that require ECC RDIMM modules. The 6400MHz speed and CL52 latency support demanding multi-threaded workloads.

Build integration

Each module uses the 288-pin DDR5 RDIMM form factor with 2Rx4 organisation and operates at 1.1V. Registered buffering and on-die ECC reduce electrical load on the memory controller, freeing signal integrity headroom for fully populated channels. No heat spreaders are fitted, so airflow across the PCB must be provided by the chassis.

Thermals and power

Running at 1.1V keeps per-module power draw low even with all eight slots filled. The absence of spreaders means module temperatures track chassis airflow directly; adequate front-to-rear cooling is required to maintain stable operation under sustained load. Acoustic contribution is limited to the system fans.

Questions about this item

Will the CL52 latency hold when all eight modules run 6400MHz continuously?

CL52 is the rated CAS latency for the kit at 6400MHz; sustained operation stays within that specification.

How much heat do eight registered 1.1V DDR5 modules produce in a 2U chassis?

Each module draws 1.10V without a heat spreader; total power scales with eight 64GB ranks under load.

Does the SuperMicro GrandTwin AS-2116GT-HNTF need a specific BIOS revision for this 512GB kit?

The kit is listed as compatible with the SuperMicro GrandTwin A+ Server AS-2116GT-HNTF.
