Compatible workstation memory kit

This 128GB kit contains two 64GB DDR5 4800 registered ECC RDIMMs built for the Thinkmate GPX-XS8-24S4-4GPU workstation. It targets IT professionals and system integrators who need validated, high-capacity memory for mission-critical server and workstation workloads.

Pre-installation checks

Verify that your workstation is the exact Thinkmate GPX-XS8-24S4-4GPU model and that its motherboard supports 288-pin DDR5 RDIMMs with ECC and registered buffering. Confirm the system accepts 2Rx4 rank organisation, 1.10V operating voltage and CL40 latency before ordering.

Thermals and power in use

Modules run at the standard DDR5 voltage of 1.10V without heat spreaders, relying on chassis airflow for cooling. Registered buffering and ECC add minimal overhead, so power draw stays consistent with the PC5-38400 specification during sustained server workloads.

Questions about this item

What comes in the box and is anything else required for installation?

The kit includes two 64 GB DDR5 4800 ECC RDIMM modules for a total of 128 GB. No additional parts are needed; install directly into the workstation's 288-pin DDR5 slots.

Should I choose the 2Rx4 64 GB modules or a different rank configuration?

This kit uses 2Rx4 organisation on each 64 GB module, matching the ThinkMate GPX-XS8-24S4-4GPU's qualified memory list for maximum capacity per channel.

What does the 4800 MT/s speed mean for real workloads on this workstation?

At 4800 MT/s with CL40 latency and 1.10 V, the modules deliver the platform's native DDR5 bandwidth, supporting ECC error correction for stable compute and rendering tasks.
