512GB DDR5 4800 ECC RDIMM Kit

This 512GB kit contains eight 64GB DDR5 4800 ECC registered DIMMs built for the Thinkmate GPX-XS8-24S4-4GPU workstation. It targets IT teams expanding memory capacity for virtualization, rendering or large dataset workloads on that specific platform.

Verify DDR5 RDIMM Slots and Population Rules

Confirm the workstation has eight available 288-pin DDR5 RDIMM slots and review the vendor documentation for required population order. The modules run at 1.1V with CL40 latency and 2Rx4 organization, so the system must support registered ECC DDR5 at this speed and rank configuration.

No Heat Spreader — Direct Airflow Required

Each module lacks a heat spreader, relying on chassis airflow for cooling. The 288-pin RDIMM form factor locks vertically into server boards, so cable routing and card clearance around all eight slots should be checked before installation to maintain consistent thermals.

Questions about this item

Does the kit include all eight 64 GB modules or do I need to buy any separately?

The kit ships with all eight 64 GB DDR5 4800 CL40 2Rx4 ECC RDIMM modules for a total of 512 GB, so nothing else is required.

Why choose the 512 GB (8 x 64 GB) CL40 kit instead of a smaller capacity or different latency?

This 512 GB kit provides the maximum supported capacity for the ThinkMate GPX-XS8-24S4-4GPU workstation at the validated DDR5 4800 CL40 speed, ensuring full ECC registered stability.

What does the DDR5 4800 (PC5-38400) rating mean for real-world throughput in this workstation?

The modules run at 4800 MT/s with CL40 timing at 1.10 V, delivering the peak bandwidth the platform’s memory controller is qualified for while maintaining ECC error correction.
