Server ECC RDIMM

This 16 GB DDR5 registered DIMM adds error-correcting memory to a Supermicro GrandTwin A+ AS-2116GT-HNTF server. It runs at 6400 MHz with CAS latency 52 and operates at 1.10 V. The module uses major OEM chips from Samsung, Micron or Hynix in a 1Rx8 configuration.

Build integration

The 288-pin RDIMM plugs directly into the server's DDR5 memory slots and requires a platform that supports registered ECC memory. No heat spreader is fitted, leaving clearance for dense multi-DIMM layouts. The single 16 GB stick frees remaining slots for future capacity expansion.

Thermals and power

At 1.10 V the module draws minimal power during typical server workloads. Bare DRAM packages rely on chassis airflow for cooling; no onboard fan or radiator is present. Acoustic output is limited to the system's existing fan noise.

Questions about this item

Will CL52 latency throttle throughput under sustained server loads?

CL52 is the rated CAS latency at 6400MHz; the module runs at 1.10V with no heat spreader, so sustained throughput depends on the server's cooling and memory-controller limits.

How much heat and power does the 1.10V RDIMM generate during all-day operation?

At 1.10V the module draws less power than higher-voltage DDR5; without a heat spreader it relies on chassis airflow, so case cooling must handle the combined DIMM load.

What server platform is required for this ECC RDIMM to function?

The module is validated for the Supermicro GrandTwin A+ AS-2116GT-HNTF and requires a DDR5 RDIMM-capable motherboard with registered ECC support.
