ECC RDIMM kit for Thinkmate workstations

This 64 GB kit supplies four 16 GB DDR4 3200 registered DIMMs built for Thinkmate GPX-XS8-14S3-4GPU workstations. ECC and registered operation protect data integrity in server-grade workloads. The modules run at 1.2 V with CL22 latency and use a 2Rx8 organisation.

Sustained throughput with registered buffering

Registered signalling reduces electrical load on the memory controller during continuous operation. ECC corrects single-bit errors in real time without halting the system. The 2Rx8 layout and 3200 MT/s rate maintain steady bandwidth through long compute jobs.

288-pin RDIMM form factor without heat spreaders

Bare modules fit dense server DIMM slots where tall spreaders would block airflow. The 288-pin DDR4 interface matches the workstation motherboard exactly. Four sticks populate quad-channel configurations for maximum capacity.

Questions about this item

How much power does the 1.20 V DDR4 3200 kit draw during continuous operation?

Each module runs at 1.20 V, the standard DDR4 voltage, so total power scales with the 64 GB capacity and the 3200 MT/s data rate.

What motherboard feature is required to use these 288-pin registered DIMMs?

The board must support DDR4 RDIMM memory with ECC and registered buffering; consumer UDIMM slots will not work.

Can the 2Rx8 organization work in a system that currently uses 1Rx4 modules?

Yes, both are dual-rank DDR4 RDIMMs; the memory controller treats them the same as long as the platform accepts 2Rx8 density.
