NEMIX RAM
A 64 GB DDR4 3200 registered ECC module with 2Rx4 organisation, CL22 latency and 1.2 V operation for Supermicro servers
This 64 GB registered DDR4 module runs at 3200 MT/s with CL22 latency and 1.20 V operation. It is built for Supermicro server and workstation platforms that require ECC error correction and registered signalling. The single 2Rx4 stick adds high-density capacity in one slot. IT professionals choose it for mission-critical workloads where data integrity matters.
The module operates at the standard 1.20 V DDR4 voltage without a heat spreader, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping keep system power draw predictable under sustained server workloads. Silent solid-state operation adds no acoustic noise to rack or tower environments.
The 288-pin RDIMM form factor fits Supermicro motherboards that support registered ECC memory, freeing non-ECC slots for other configurations. Single-module population leaves additional DIMM sockets open for future expansion up to the platform limit. Compatibility testing under load ensures stability without requiring BIOS changes beyond standard JEDEC profiles.

Power down, open the chassis, align the notch on the module with the slot key, press firmly until both retention clips click, then verify in BIOS that the 64 GB module registers at 3200 MT/s with ECC enabled.
No scheduled maintenance is required; if a correctable error count rises or the module fails POST, replace the single 64 GB stick — there are no batteries, fans or firmware to service.
The CAS 22 latency and 1.2 V JEDEC voltage set the timing and thermal ceiling; sustained throughput will plateau at the rated 3200 MT/s before any throttling occurs.
