NEMIX RAM
Eight 16 GB DDR4 3200 MHz ECC registered DIMMs totalling 128 GB at CL22 and 1.2 V for ThinkMate workstations
This 128GB kit contains eight 16GB DDR4 3200MHz registered DIMMs with ECC and CL22 latency. It operates at 1.2V and uses 2Rx8 organisation on 288-pin modules. The memory is validated for ThinkMate GPX-XS8-14S3-4GPU workstations requiring registered server memory.
Confirm your motherboard accepts DDR4 registered ECC RDIMMs and provides eight 288-pin slots before ordering. Standard unbuffered desktop memory will not function in this configuration. Check the system manual for maximum supported capacity per slot and total system limit to ensure the 128GB kit is fully recognised.
Error-correcting code detects and corrects single-bit errors during continuous operation. Registered buffering reduces electrical load on the memory controller when all eight modules are populated. The 1.2V standard voltage and CL22 timing maintain consistent throughput under prolonged server workloads without exceeding specification.

The package includes eight 16GB RDIMMs for a total of 128GB, ready to populate all available slots in compatible Thinkmate workstations
CL22 is the CAS latency at 3200 MT/s; the registered buffer adds one cycle, so the effective latency suits stability-focused server workloads rather than low-latency desktop tuning
Yes, the modules run at the standard 1.20V DDR4 voltage used by registered server platforms, matching the electrical spec of the Thinkmate GPX-XS8-14S3-4GPU workstation
