ThinkMate-Compatible DDR4 Server Memory

This 64GB kit uses two 32GB DDR4-3200 ECC registered DIMMs built for ThinkMate GPU-optimised servers. Each module runs at 1.2V with CL22 latency and a 2Rx8 organisation. The registered design adds a buffer that stabilises heavy multi-module configurations.

Replaces Slower or Non-ECC DIMMs

Upgrading from lower-speed DDR4 or unbuffered memory removes bandwidth bottlenecks and adds error correction for data integrity. The jump is worth it when workloads demand sustained throughput and protection against silent corruption across all 64GB.

Handles Large GPU-Accelerated Workloads

The 64GB capacity feeds multi-GPU servers running training, inference or rendering jobs that exceed 32GB. Headroom narrows when datasets or model weights grow beyond the installed amount, requiring additional DIMM slots or higher-density modules.

Questions about this item

Will these 288-pin RDIMM modules fit the memory slots on my THINKMATE GPX-QN4-22E2-4NVLINK server?

Yes, the 288-pin DDR4 RDIMM form factor matches the registered DIMM slots used in the listed THINKMATE GPU-optimised servers.

Do I need to populate the slots in a specific order when installing the two 32 GB modules?

Install both modules in the same channel pair as shown in the server manual; the common mistake is placing them in adjacent slots that belong to different channels.

How do I know when one of the 32 GB ECC RDIMM modules should be replaced?

The server will log corrected ECC errors; if uncorrectable errors appear or the module fails POST, replace the affected 32 GB stick.
