NEMIX RAM
16 GB DDR4 3200 ECC registered kit (2 × 8 GB, CL22, 1.2 V, 288-pin) validated for Tyan TS75A-B8252 servers
This 16 GB kit contains two 8 GB DDR4 3200 RDIMM modules validated for the Tyan Transport HX TS75A-B8252 server platform. ECC and registered operation protect data integrity in multi-socket workloads. IT teams can install the pair in minutes to expand memory capacity without reconfiguring the chassis.
Each module runs at 1.20 V with a CL22 latency profile, keeping power draw modest while the register buffers address and command signals. The absence of heat spreaders allows unrestricted airflow across the PCB in dense 1U or 2U enclosures. ECC correction runs transparently during normal operation.
The 1Rx8 organisation fits any 288-pin DDR4 RDIMM slot on the qualified motherboard, freeing remaining slots for future expansion. No additional cooling hardware or firmware updates are required beyond the system BIOS. Builders needing higher density or non-ECC memory must select a different kit.

Power down, 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 16 GB are detected at 3200 MT/s; the step often missed is seating both clips fully on each module.
No scheduled maintenance is required; keep the server's air filters clean so the registered DIMMs stay cool, and replace a module only if ECC logs report uncorrectable errors or the system fails to POST with that stick installed.
The CAS latency of 22 cycles at 3200 MT/s sets the timing floor; under continuous heavy workloads the memory controller will hit this latency ceiling before voltage or thermal limits become a factor.
