Capacity and Configuration

This 256GB kit contains sixteen 16GB DDR5 4800 modules built for the ThinkMate GPX-XH8-22S4-8GPU server. Registered ECC operation and a 1Rx8 layout provide the data integrity required for GPU-optimised workloads.

Upgrade Path

The kit replaces lower-capacity or non-ECC memory to reach the full 256GB supported by the platform. The jump is worth it when workloads exceed the current memory ceiling and registered buffers are needed for stability.

Installation Notes

Modules use the standard 288-pin DDR5 RDIMM form factor and operate at 1.10V. Populate all sixteen slots following the server manual; mismatched ranks or missing ECC support will prevent the system from posting.

Questions about this item

What physical slot does the 288-pin DDR5 RDIMM require on the THINKMATE GPX-XH8-22S4-8GPU motherboard?

It fits a standard 288-pin DDR5 RDIMM slot; the server has 16 such slots for the full 256 GB kit.

Which population order does the THINKMATE GPX-XH8-22S4-8GPU manual specify for 16 identical 1Rx8 modules?

Fill all 16 slots following the motherboard’s labelled channel sequence; the common mistake is skipping a channel and leaving bandwidth unused.

When should the 1.1 V DDR5 modules be replaced in a continuous GPU-optimised workload?

ECC RDIMMs have no scheduled replacement interval; swap a module only if the system logs correctable errors that exceed the platform’s threshold.
