1.5 TB DDR5 ECC RDIMM kit for ThinkMate GPU servers

This 1.5 TB memory kit contains twelve 128 GB DDR5 4800 registered DIMMs with ECC and a CAS latency of CL40. It is built for the ThinkMate GPX-XH8-22S4-8GPU GPU-optimised server and operates at 1.1 V. The modules use 4Rx4 organisation and 288-pin DDR5 form factor.

Upgrade from lower-capacity DDR5 RDIMMs

The jump is worth it when workloads such as large-model training, simulation or in-memory databases exceed the capacity of smaller kits. Adding the full 12-module set maximises the server’s memory bandwidth at DDR5 4800 speeds. Partial population is possible but leaves bandwidth and capacity unused.

Verify motherboard slot count

Confirm the ThinkMate server has twelve DDR5 RDIMM slots available and that the platform’s qualified-vendor list includes 4Rx4 128 GB modules at 4800 MT/s. Check that the BIOS version supports the full 1.5 TB configuration. Ensure the chassis airflow can accommodate twelve modules without additional cooling.

Questions about this item

Will the 12x128GB 288-pin DDR5 RDIMMs fit the THINKMATE GPX-XH8-22S4-8GPU server?

The kit is built for the THINKMATE GPX-XH8-22S4-8GPU GPU-optimized server and uses the standard 288-pin DDR5 RDIMM form factor required by that platform.

What is the correct sequence for populating the 12 slots with these 4Rx4 registered modules?

Follow the server manual's population order; install modules in the prescribed slots per channel so the memory controller initialises all 12 ranks at 4800 MT/s.

When should the 1.5TB ECC RDIMM kit be swapped out in a continuous server deployment?

Replace modules only if ECC correctable-error counts rise sharply or the system logs uncorrectable errors, indicating chip degradation.
