NEMIX RAM
A 192 GB DDR5 kit of six 32 GB registered ECC modules running at 4800 MT/s CL40 and 1.1 V for SuperMicro X13SEI-F and X13SEI-TF servers
This 192 GB kit contains six 32 GB DDR5 4800 registered DIMMs built for SuperMicro X13SEI-F and X13SEI-TF motherboards. It targets server and workstation administrators who need maximum ECC capacity for virtualization, database or scientific workloads. The modules run at 1.1 V with CL40 latency and use a 1Rx4 organisation across 288 pins. Buyers who need non-ECC memory or lower-density modules should look elsewhere.
Each stick is a 288-pin RDIMM, so the system must provide registered-memory support and six available DDR5 slots. The kit frees administrators from mixing capacities or speeds because all six modules are matched at 4800 MT/s and CL40. No heat spreaders are fitted, leaving clearance for dense CPU coolers or airflow-optimised chassis. Builds that only have four DIMM slots cannot use the full kit.
The 1.1 V operating voltage keeps power draw predictable during continuous multi-threaded tasks such as compile farms or in-memory analytics. CL40 latency remains stable because the registered buffer absorbs electrical load across all six ranks. Modules are stress-tested under load before shipping, so error-correction performance does not degrade during extended uptime. Systems without adequate airflow over bare PCBs may see higher temperatures.

The modules operate at the rated CL40 timing at 4800 MT/s; sustained workloads keep that latency because the registered design and 1.10V voltage maintain signal integrity without throttling.
No heat spreaders are fitted, so the chips rely on chassis airflow; power draw stays at the standard 1.1V DDR5 level, adding minimal heat and no audible noise from the memory itself.
The kit is validated for SuperMicro X13SEI-F and X13SEI-TF motherboards; populate the six DDR5 RDIMM slots and enable ECC in BIOS for full 192GB registered operation.
