NEMIX RAM
1TB DDR4 3200 ECC registered server kit with sixteen 64GB 4Rx4 modules at CL22 and 1.2V for Thinkmate high-density systems
This 1 TB DDR4 ECC RDIMM kit contains sixteen 64 GB modules built for THINKMATE HDX-QT24 and HDX-QN24 high-density servers. Registered buffering and on-die ECC protect data integrity in mission-critical workloads. The kit targets IT teams expanding memory capacity in qualified enterprise platforms.
Modules insert vertically into 288-pin DDR4 slots; the registered design adds a clock cycle so the memory controller must support registered DIMMs. Population rules vary by motherboard, so the system manual should be consulted before installing all sixteen sticks. Mixing ranks or speeds can prevent the server from posting.
All modules are stress-tested under load before shipping to verify stability during continuous operation. The 1.2 V operating voltage and CL22 latency at 3200 MT/s are maintained across extended compute tasks. ECC correction handles single-bit errors without interrupting long-running services.
