Server-grade DDR5 ECC RDIMM kit

This 256 GB kit comprises two 128 GB DDR5 modules built for the Supermicro GrandTwin A+ Server AS-2116GT-HNTF. Registered ECC operation provides the data integrity required in enterprise workloads. It is not suited for desktop boards that accept only unbuffered memory.

DDR5 6400 MHz CL52 registered specification

The modules run at 6400 MHz with a CAS latency of 52 and a 2Rx4 organisation. Registered buffering and on-die ECC are mandatory for the target platform; systems that require unbuffered DIMMs or a different speed grade will not accept this kit.

Low-voltage thermal profile

Each DIMM operates at 1.1 V without a heat spreader, relying on chassis airflow for cooling. Power draw remains modest for the density, and acoustic impact is negligible in a properly ventilated server enclosure.

Questions about this item

What does the 6400MHz rating mean once the kit is installed in the Supermicro AS-2116GT-HNTF?

The modules will run at 6400 MT/s, delivering PC5-51200 bandwidth per stick when the server's memory controller is configured for that speed.

How does the DDR5 RDIMM interface and CL52 latency affect real-world throughput?

Registered DDR5 adds a clock cycle of buffering for signal integrity, and CL52 sets the minimum read latency at that data rate.

What physical slot and clearance does the 288-pin 2Rx4 module need in the GrandTwin chassis?

Each 128 GB stick occupies one standard 288-pin DDR5 RDIMM socket; the dual-rank 2Rx4 layout fits the server's memory channel population rules.
