32 GB DDR4 3200 ECC registered DIMM with CL22 latency for Thinkmate GPU-optimised servers
This 32GB registered DIMM delivers error-correcting DDR4 memory at 3200MHz for Thinkmate GPX-QN4-22E2-4NVLINK and GPX-QN12-24E2-10GPU GPU-optimised servers. The module operates at 1.2V with CL22 latency and uses a 2Rx8 organisation built from major OEM chips. It targets administrators who need validated capacity for memory-intensive workloads.
The registered buffer reduces electrical load on the memory controller, allowing stable operation when all slots are populated under continuous compute pressure. ECC circuitry detects and corrects single-bit errors in real time, preventing silent data corruption during long training runs or rendering jobs. The 2Rx8 rank structure supports high-density configurations without exceeding rank-per-channel limits.
Without a heat spreader the module relies on chassis airflow, which is plentiful in the target Thinkmate GPU servers. Operating at 1.20V keeps power draw low per gigabyte, reducing the thermal contribution to the overall system budget. Silent operation is inherent because no active cooling is attached to the DIMM itself.

The module runs at 1.20 V, the standard voltage for DDR4, keeping power draw low even during continuous server workloads.
You need a server or workstation motherboard with DDR4 RDIMM slots and a chipset that supports ECC registered memory.
Yes, matched speed, voltage and ECC registration allow mixed-capacity populations on compatible multi-channel server boards.
