NEMIX RAM
A 128 GB DDR5 registered ECC kit of four 32 GB modules running at 6400 MT/s with CL52 latency for SuperMicro X14SBM-TF servers
This 128 GB kit delivers four 32 GB DDR5 6400 registered DIMMs with ECC and CL52 latency. It is built for the SuperMicro X14SBM-TF server board and other compatible platforms that require registered memory. System integrators and IT teams use it to maximise capacity on supported workstations and servers.
Registered buffering and on-die ECC keep data integrity intact during continuous workloads such as virtualisation, database serving or AI training. The 1.1 V operating voltage helps limit thermal output while the modules run at the rated 6400 MT/s speed. No heat spreaders are fitted, so airflow across the DIMM slots must be adequate.
Each module uses the standard 288-pin DDR5 RDIMM form factor with a 2Rx4 organisation. The lack of heat spreaders reduces height for dense chassis but places more reliance on case ventilation. Four modules populate all channels on the target board for full bandwidth utilisation.

The modules operate at 1.10V without a heat spreader; they rely on the server chassis airflow for cooling and have no moving parts, so they add no audible noise.
The motherboard must provide DDR5 RDIMM slots that support registered ECC memory and a BIOS capable of initialising 6400 MT/s modules at CL52.
All four modules are matched 2Rx4 PC5-51200 parts; mixing ranks or speeds can prevent the system from training at 6400 MT/s, so identical modules are recommended.
