128GB DDR5 ECC RDIMM kit for Supermicro GrandTwin

This registered DDR5 memory kit provides 128GB total capacity across two 64GB modules. It is built for the Supermicro GrandTwin A+ Server AS-2116GT-HNTF where ECC and registered signalling are required. The modules run at 6400MHz with CL52 latency at 1.1V.

Tool-free DIMM installation

Each 288-pin RDIMM inserts vertically into the server board slots; the registered buffer adds slight insertion force so press evenly until the ejectors click. The main risk is mixing registered and unbuffered DIMMs or populating slots in the wrong channel order, which prevents the system from posting.

Sustained throughput at 6400MHz with ECC overhead

Under continuous load the kit maintains its rated 6400MHz data rate while the ECC logic corrects single-bit errors without halting the pipeline. The 2Rx4 organisation spreads accesses across two ranks per module, helping bandwidth stability during long compute or virtualisation runs.

Questions about this item

How do I confirm the kit is running at 6400MHz CL52 after installing it in the Supermicro AS-2116GT-HNTF?

Enter the system BIOS or UEFI and check the memory information screen; it should report 6400MHz speed and CL52 latency for each 64GB module.

What comes in the package and is anything else required for installation?

The box contains two 64GB DDR5 6400MHz ECC RDIMM modules (128GB total); no extra parts or cables are needed for installation in compatible Supermicro servers.

Should I choose this 128GB 2Rx4 kit or a different capacity for the AS-2116GT-HNTF?

This 128GB (2 x 64GB) 2Rx4 kit matches the qualified configuration for the Supermicro GrandTwin A+ AS-2116GT-HNTF; select it when you need the full 128GB capacity.
