Two 64 GB DDR4 3200 ECC registered modules at CL22 1.2 V for ThinkMate GPU-optimised servers
This 128GB DDR4 ECC RDIMM kit targets ThinkMate GPX-QN4 and GPX-QN12 GPU-optimised servers that require registered error-correcting memory for continuous compute workloads. The two 64GB modules deliver 128GB total capacity at 3200 MT/s with CL22 latency. System administrators upgrading memory in these specific platforms will find the kit validated for compatibility.
Each module uses 4Rx4 organisation built from Samsung, Micron or Hynix components and operates at 1.20V without heat spreaders. The registered buffer reduces electrical load on the server memory controller, while ECC detects and corrects single-bit errors to maintain data integrity during long training or inference runs. The kit includes only the two RDIMMs; no additional cables, software or cooling hardware are supplied.
The DDR4 3200 (PC4-25600) interface caps bandwidth at the JEDEC standard rate for this generation, so throughput cannot exceed what the memory controller and 288-pin bus allow. CL22 latency is fixed by the module SPD and cannot be tightened without stability risk. Servers needing higher bandwidth per channel or lower latency must move to a newer memory generation, which this platform does not support.

The 4Rx4 organisation is fixed by the module design; no firmware changes it and replacement is only needed if a module fails.
CAS latency 22 at DDR4 3200 sets the random-access floor; sustained bandwidth caps at the PC4-25600 data rate before latency becomes the bottleneck.
Each module draws 1.20 V at DDR4 3200; total power stays within standard RDIMM limits so a normal server airflow path handles the heat without extra cooling.
