NEMIX RAM
ECC registered DDR4 kit adds 256 GB across eight 32 GB modules at 3200 MT/s with CL22 latency
This 256GB kit contains eight 32GB DDR4 3200 registered DIMMs built for Thinkmate STX-NL-QE24 E3 nearline storage servers. Each module operates at 1.2V with CL22 latency and 2Rx8 organisation. The memory is validated for the target platform to ensure stability in mission-critical workloads.
Registered ECC RDIMMs add a clock cycle of buffering that stabilises heavy loads but caps maximum frequency at the JEDEC DDR4 3200 standard. Error correction detects and corrects single-bit errors, yet the registered design prevents use in consumer desktop boards that expect unbuffered modules. Mixed-rank populations may further reduce achievable speeds.
Modules use Samsung, Micron or Hynix components without heat spreaders, relying on server chassis airflow for cooling. The 288-pin RDIMM form factor fits only registered DIMM slots keyed for DDR4 ECC. Eight modules fill all available channels on compatible Thinkmate systems, leaving no room for further expansion without removing existing sticks.

The kit supplies 256GB across eight 32GB modules; choose it when your workload needs that full capacity and the server has eight free DIMM slots.
The modules run at 3200 MT/s with a CAS latency of 22 cycles, giving registered ECC bandwidth suited to the Thinkmate nearline storage platform.
The 288-pin DDR4 RDIMM form factor caps each module at 32GB and the kit at 256GB total, while the registered design supports the 3200 MT/s data rate on the server motherboard.
