Capacity and role

This 768GB kit delivers six 128GB DDR5 ECC RDIMM modules for the SuperMicro GrandTwin AS-2116GT-HNTF. Registered buffering and error correction suit multi-socket server workloads that demand maximum capacity and data integrity.

Before ordering

Verify that the GrandTwin AS-2116GT-HNTF has six free 288-pin DDR5 slots and that the BIOS supports 2Rx4 registered modules at the rated speed. The kit is built for this specific system; other platforms may not recognise the density or register configuration.

Thermals noise and power

Modules run at 1.1V without heat spreaders, relying on server chassis airflow for cooling. Expect silent operation with no active components; total power draw scales with all six DIMMs populated under sustained load.

Questions about this item

Does the kit include six 128 GB modules or do I need to buy additional sticks?

The kit contains six 128 GB DDR5 RDIMMs, giving a total of 768 GB, so no extra modules are required.

Why choose the 6400 MHz CL52 1.1 V version over slower or lower-voltage options?

This version runs at 6400 MHz with CL52 latency at 1.1 V, matching the SuperMicro GrandTwin AS-2116GT-HNTF specification for maximum supported speed.

What does the 6400 MHz rating deliver once the modules are installed in the server?

The modules operate at DDR5-6400 (PC5-51200) with CL52 timing, providing the peak bandwidth the platform is validated for.
