128 GB DDR4 3200 ECC registered RDIMM with CL22 latency and 1.2 V operation for Thinkmate GPU-optimised servers
This 128GB DDR4 3200 module is built for Thinkmate GPX-XT6-24S3-8NVLINK GPU-optimised servers that require registered ECC memory. It delivers 128GB in a single 288-pin RDIMM running at 1.20V with CL22 latency. The 4Rx4 organisation suits high-capacity server boards that support quad-rank modules. It targets administrators upgrading memory in compatible Thinkmate platforms.
The stick plugs directly into a 288-pin DDR4 RDIMM slot on a validated Thinkmate motherboard; no extra cabling or adapters are needed. Registered signalling and on-die ECC reduce electrical load on the memory controller, freeing electrical headroom for additional modules in the same channel. Heat spreader is absent, so airflow across the PCB must be provided by the server chassis fans. Compatibility is limited to the listed Thinkmate system; other platforms are not verified.
Each module undergoes rigorous stress testing under load before shipment to confirm reliable operation during extended workloads. The 1.20V operating voltage and CL22 timing remain consistent across long compute sessions in the target Thinkmate server. Quad-rank density increases capacity per slot without raising voltage, helping thermal behaviour in densely populated memory configurations. Lifetime replacement warranty backs the validated reliability.

The 4Rx4 organisation spreads 128 GB across four ranks, letting the memory controller interleave requests and maintain bandwidth during long compute jobs.
At 1.2 V the module draws minimal power and has no heat spreader, so case airflow alone keeps temperatures in the normal DDR4 operating range.
A THINKMATE GPX-XT6-24S3-8NVLINK motherboard with DDR4 RDIMM slots and ECC support in the BIOS is needed for the module to be recognised.
