64GB DDR5 4800 ECC RDIMM for Thinkmate GPU Servers

This 64GB module runs at DDR5 4800 with CL40 latency and 1.1V operation. It uses a 2Rx4 registered ECC design built with major OEM DRAM chips. The part is validated for Thinkmate GPX-QH24-24E4-8GPU and GPX-QH14-28E4-8HGX GPU-optimised servers.

Check DDR5 RDIMM slots

Verify that your Thinkmate server accepts 288-pin DDR5 RDIMM modules and supports 64GB single-rank-per-module density. Confirm the memory population rules for your specific CPU configuration before ordering. Registered ECC memory requires a compatible server motherboard and cannot be used in standard desktop platforms.

Thermals noise and power draw in normal use

The module operates at 1.1V without a heat spreader, relying on server chassis airflow for cooling. Registered ECC RDIMMs typically run quietly under standard server workloads with power draw proportional to capacity and speed. Actual thermal performance depends on your system's cooling design and memory load.
