Capacity and configuration

This kit provides 256GB of DDR4 memory across four 64GB LRDIMM modules. It is built for ThinkMate GPX-QT8-24E2-8GPU GPU-optimised servers that require load-reduced ECC memory at 2666 MT/s.

Speed, latency and headroom

The modules run at DDR4 2666 (PC4-21300) with a CAS latency of 19 and operate at 1.2V. Four-rank 4Rx4 organisation and ECC give maximum density per slot, while the load-reduced buffer reduces electrical load on the memory controller for stable operation at full capacity.

Form factor and daily handling

Each module uses the standard 288-pin DDR4 LRDIMM form factor without a heat spreader, relying on server chassis airflow for cooling. The kit is validated for the target ThinkMate platform, so installation follows the system manual without additional configuration steps.

Questions about this item

Will the 2666 MT/s DDR4 LRDIMM kit run at the speed of the slowest modules already installed in the THINKMATE server?

The kit operates at DDR4 2666 (PC4-21300). When mixed with slower modules, the system typically clocks all memory to the lowest common speed supported by the platform.

How can I verify the 4Rx4 ECC LRDIMM modules are recognised correctly after installation?

Check the BIOS or UEFI memory information screen; it should show 256 GB total across four 64 GB modules, DDR4 2666, ECC active, and 4Rx4 organisation.

What comes in the package and are any extra components required for installation?

The box contains four 64 GB DDR4 2666 ECC LRDIMM modules (288-pin, 1.2 V, CL19). No additional parts are needed; install directly into compatible LRDIMM slots.
