System-Specific DDR5 ECC RDIMM Kit

This 256GB kit contains four 64GB registered DDR5 modules rated at 4800MT/s with CL40 latency and 1.10V operation. It is built for ThinkMate GPU-optimised servers that require ECC RDIMM memory. The modules use 2Rx4 organisation and 288-pin form factor.

Suited for ThinkMate GPX-QH24-24E4-8GPU

Buyers needing memory for other platforms should verify their motherboard supports DDR5 4800 registered ECC RDIMMs before purchase. Systems requiring unbuffered or non-ECC modules cannot use this kit.

Registered ECC with 2Rx4 organisation

The registered buffer and error-correcting code are mandatory for the target ThinkMate server platforms. Modules without these features will not function in the qualified systems.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the memory slots on a ThinkMate GPX-QH24-24E4-8GPU server?

Yes, the 288-pin DDR5 RDIMM form factor matches the registered DIMM slots used in the compatible ThinkMate GPU-optimised servers.

What is the correct way to install the four 64 GB modules so the server recognises all 256 GB?

Populate the slots in the order specified by the server manual, typically one module per channel across all memory controllers, and ensure each RDIMM clicks fully into the 288-pin socket.

When should the ECC RDIMM kit be replaced if correctable error counts start rising in the system logs?

Replace modules when the platform firmware reports persistent correctable ECC errors or when memory diagnostics flag a specific 64 GB RDIMM as degraded.
