Eight 128 GB DDR4-3200 ECC registered modules deliver 1 TB of server memory for Thinkmate GPU-optimised systems
This kit provides 1TB of DDR4 3200 registered ECC memory across eight 128GB modules. It is built for Thinkmate GPX-QN4-22E2-4NVLINK and GPX-QN12-24E2-10GPU GPU-optimised servers. The modules run at 1.2V with CL22 latency and a 4Rx4 organisation. They are validated for mission-critical enterprise workloads.
Administrators scaling GPU-dense Thinkmate platforms will match the qualified part number MR25600-744K8. The 4Rx4 rank structure and registered buffer require a motherboard that supports quad-rank registered DIMMs. Builders needing unbuffered UDIMMs, non-ECC memory, or lower-density modules for consumer boards should select a different kit.
The single specification that decides fit is the 1TB kit configured as eight 128GB registered ECC modules at DDR4 3200. This exact density and rank layout must be supported by the target Thinkmate server memory controller.
