NEMIX RAM
Eight 64 GB DDR4 3200 ECC RDIMM modules at 1.2 V with CL22 latency for the Tyan Transport CX GC68A-B8036-LE server
This NEMIX RAM kit supplies 512GB of DDR4 memory across eight 64GB modules. It is built as a system-specific upgrade for the Tyan Transport CX GC68A-B8036-LE server platform. The registered ECC design targets enterprise workloads that demand data integrity and large memory footprints. Buyers needing non-ECC memory or desktop form factors should look elsewhere.
Each module operates at 1.2V without a heat spreader, relying on chassis airflow for cooling. The DDR4 3200 CL22 timing and 4Rx4 organisation keep power draw predictable during typical server duties. Registered buffering adds a clock cycle but reduces electrical load on the memory controller. Systems with restricted airflow or passive cooling may require additional attention.
All modules are stress tested under load before shipping to verify stability in continuous operation. The ECC function corrects single-bit errors on the fly during extended compute tasks. Registered signalling helps maintain signal quality across all eight slots over long periods. Workloads exceeding the 512GB capacity or requiring lower latency than CL22 will need a different memory configuration.

Power off the server, open the chassis, align each module's notch with the slot key, press firmly until both retention clips click, then verify in BIOS that all eight 64 GB modules are detected at 3200 MT/s.
The modules have no moving parts and no heat spreaders; dust the slots with compressed air during routine server cleaning and reseat only if ECC errors appear in system logs.
The four-rank-per-module density increases electrical loading on the memory bus, so the platform may drop to a lower data rate or require reduced DIMM population to maintain stability.
