256GB DDR4-3200 ECC registered kit (4×64GB) at CL22 and 1.2V for ThinkMate GPX-XS12-24S3-8GPU servers
This 256GB kit supplies four 64GB DDR4 3200 ECC registered DIMMs validated for ThinkMate GPX-XS12-24S3-8GPU GPU-optimised servers. Each module runs at 1.2V with CL22 latency and a 4Rx4 organisation. The registered design adds a buffer that helps the memory controller maintain signal integrity across all populated slots. Buyers needing non-ECC or unbuffered UDIMMs for consumer boards cannot use this kit.
Operating at the standard DDR4 voltage of 1.2V keeps per-module power draw low in typical server workloads. The modules ship without heat spreaders, relying on the chassis airflow that ThinkMate GPU servers provide. No active cooling is present on the DIMMs themselves, so acoustic contribution is limited to the system fans already moving air across the memory banks.
ECC circuitry detects and corrects single-bit errors during extended compute or GPU-accelerated tasks, reducing the chance of silent data corruption. Registered buffering stabilises the command bus when all twelve DIMM slots are populated, preventing timing drift during long runs. The 4Rx4 rank density maximises capacity per channel but requires a memory controller qualified for quad-rank registered modules.

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until the side clips lock, then verify all four 64GB modules are recognised in the BIOS before closing the case.
The modules have no heat spreaders and no moving parts, so no scheduled maintenance is required; only a failed stick would need replacement under the lifetime replacement warranty.
The CAS 22 timing is fixed, so latency-sensitive, sustained throughput tasks will hit the CL22 limit before bandwidth or voltage constraints appear.
