128GB DDR4 3200 ECC RDIMM

This single 128GB registered DIMM delivers DDR4 3200 speed with error-correcting code for Supermicro servers and workstations. It targets administrators who need maximum capacity per slot in memory-intensive applications.

Registered 4Rx4 module for Supermicro platforms

The 288-pin RDIMM operates at 1.2V with CL22 latency and requires a motherboard that supports registered ECC memory and 4-rank x4 organisation. It occupies one DIMM slot, leaving remaining channels free for further expansion.

Stress-tested stability under sustained load

Modules are validated under continuous workload to maintain data integrity during extended compute tasks. The registered buffer and ECC function reduce electrical loading on the memory controller, helping sustain throughput during long-running server operations.

Questions about this item

Will the CL22 latency become a bottleneck during sustained server workloads?

CL22 is the rated CAS latency for this 3200 MT/s module; it sets the minimum cycle delay for every random access under continuous load.

How much heat does a 1.2 V 4Rx4 RDIMM generate when running all day?

At 1.2 V the module draws standard DDR4 power; with no heat spreader it relies on chassis airflow to stay within JEDEC thermal limits.

What motherboard feature must my Supermicro system already have to accept this 288-pin registered DIMM?

The board must provide a DDR4 RDIMM slot that supports 4Rx4 registered ECC modules at 3200 MT/s.
