NEMIX RAM
A 64GB kit of four 16GB DDR4 3200 ECC registered DIMMs with CL22 latency and 1.2V operation for compatible Tyan servers
This 64 GB kit contains four 16 GB DDR4 3200 registered ECC RDIMM modules built for the Tyan Transport CX GC68-B8036-LE platform. It targets administrators who need validated, high-capacity memory for mission-critical server and workstation workloads. Each module runs at 1.2 V with a CL22 latency and a 2Rx8 organisation using major OEM DRAM. The 288-pin form factor matches the board’s DDR4 RDIMM slots exactly.
Registered buffering and ECC logic keep electrical load predictable during typical multi-user or virtualisation tasks. Operating at the standard 1.2 V DDR4 voltage, the modules draw only the power required for the configured 3200 MT/s rate without additional heat spreaders. Passive cooling in a properly ventilated chassis is sufficient; no active fans or extra airflow paths are needed for baseline operation.
All modules are stress-tested under load before shipping to verify stability during extended compute or database sessions. The registered design reduces signal loading on the memory controller, helping maintain timing integrity when all four slots are populated at 3200 MT/s. ECC correction continues to protect data integrity throughout prolonged heavy utilisation without performance throttling.

Power down the server, open the chassis, and seat each 16GB module firmly until the ejector clips click; the step often missed is populating the four slots in the exact channel order shown in the Tyan manual so the 2Rx8 ranks interleave correctly.
The modules have no heat spreaders and no moving parts, so no routine maintenance is required; replacement only occurs if a module fails, which is covered by the manufacturer lifetime replacement warranty.
The CL22 latency at 1.20V is the first bottleneck; sustained heavy traffic hits the timing ceiling before the 25600 MT/s bandwidth or the registered buffer saturates.
