Server-grade capacity for GrandTwin A+

This 256 GB kit delivers eight 32 GB DDR5 ECC RDIMM modules built for the Supermicro GrandTwin A+ Server AS-2116GT-HNTF. Registered buffering and error-correcting code protect data integrity in multi-socket workloads. The kit targets administrators who need maximum supported memory per node without mixing module densities.

Sustained throughput at rated speed

Each module runs at 6400 MT/s with CL52 latency and 1.10 V across all eight slots. Dual-rank 2Rx8 organisation keeps bandwidth stable during long compile jobs, database scans or virtualisation workloads. The registered design reduces electrical load on the memory controller so performance does not degrade as temperatures rise.

Low-voltage operation without spreaders

The 1.1 V DDR5 standard limits power draw per DIMM while the bare PCB allows unrestricted airflow in the GrandTwin chassis. No heat spreaders means tighter slot spacing is not an issue and acoustic profile stays neutral under typical server fan curves.

Questions about this item

Will the 1.1 V DDR5 modules add noticeable heat or fan noise when the AS-2116GT-HNTF runs continuously?

These RDIMMs operate at the standard 1.1 V DDR5 voltage with no heat spreader, so thermal output matches typical registered server memory; the chassis fans already designed for the GrandTwin platform will handle the load.

Does the Supermicro AS-2116GT-HNTF need a specific BIOS version or CPU stepping before it will recognise this 8 x 32 GB kit?

The kit is validated for the GrandTwin A+ AS-2116GT-HNTF; install the modules in the supported DDR5 RDIMM slots and the system will detect the 256 GB capacity at 6400 MT/s CL52.

Can I mix these 2Rx8 CL52 sticks with any existing DDR5 RDIMMs of a different rank or speed in the same server?

Mixing ranks or speeds is not recommended; for stable operation populate all channels with identical 2Rx8 6400 MT/s CL52 modules as supplied in this kit.
