NEMIX RAM
A 2 TB registered DDR4 ECC kit of sixteen 128 GB modules running at 3200 MHz CL22 1.2 V for Thinkmate nearline storage servers
This 2 TB kit assembles sixteen 128 GB DDR4 3200 RDIMMs into a single validated package for Thinkmate STX-NL-QE24 E3 nearline storage servers. Registered signalling and on-die ECC protect data integrity across every module. The CL22 latency and 1.20 V operating point match the platform specification. System administrators scaling memory for large datasets can deploy the full capacity without mixing kits.
Registered buffering places a register between the memory controller and each DRAM rank, reducing electrical load during continuous read and write cycles typical of nearline storage workloads. ECC corrects single-bit errors on the fly, preventing silent corruption during long backup or replication jobs. The 4Rx4 organisation distributes accesses across four ranks per module, keeping bandwidth steady under heavy queue depths. CL22 timing remains stable at the rated 3200 MT/s data rate.
Each 288-pin RDIMM uses a low-profile bare PCB, allowing tight slot spacing in the Thinkmate chassis without clearance conflicts. The 1.2 V supply reduces thermal output compared with higher-voltage server memory, simplifying airflow management in densely populated bays. Major OEM Samsung, Micron or Hynix DRAM ensures consistent quality across all sixteen modules. Builders who need more than 2 TB or a different form factor must look beyond this specific kit.

Registered ECC modules at 1.20V typically run cooler than unbuffered DIMMs; the 4Rx4 organisation spreads load across ranks, helping thermals during sustained workloads.
Sixteen 288-pin DDR4 RDIMM slots are needed; the host must support 4Rx4 registered ECC at DDR4 3200 with enough channels to populate all 16 sockets.
Mixing 4Rx4 with 2Rx4 or 2Rx8 registered ECC at the same speed is usually supported, but the memory controller may down-clock or limit total rank count per channel.
