Server memory kit for GPU-optimised ThinkMate

This 768GB kit consists of twelve 64GB DDR4 2666 LRDIMM modules built for ThinkMate GPX-QT8-24E2-8GPU servers. Each module runs at 1.2V with CL19 latency and uses a 4Rx4 load-reduced design. ECC protection and registered signalling help maintain data integrity under sustained multi-GPU workloads.

Replaces lower-capacity DDR4 RDIMM or LRDIMM sets

Moving to twelve 64GB load-reduced modules lets the platform reach its maximum supported memory without exceeding electrical loading limits per channel. The upgrade is worth it when virtualisation density, GPU compute buffers or large dataset caching exceed the capacity of standard registered DIMM populations.

Limited to DDR4 2666 transfer rates

The memory operates at PC4-21300 speeds and cannot run at DDR5 velocities or fit DDR5 slots. Load-reduced buffering reduces electrical load on the memory controller but adds latency compared to unbuffered modules. Systems must support 4Rx4 LRDIMM topology and ECC to use this kit.

Questions about this item

Will these 288-pin DDR4 LRDIMM modules fit the memory slots on a ThinkMate GPX-QT8-24E2-8GPU server?

Yes, the kit is built for that exact server model and uses the standard 288-pin DDR4 LRDIMM form factor the board requires.

What is the correct population order for the twelve 64 GB modules when installing them in the ThinkMate GPX-QT8-24E2-8GPU?

Follow the server manual's channel sequence; the common mistake is skipping a channel or mixing ranks instead of filling all twelve slots identically.

How can I tell if one of the twelve 64 GB modules needs replacement later?

Run a memory diagnostic; persistent ECC correctable errors or uncorrectable failures on a specific DIMM indicate that module should be swapped.
