128GB LRDIMM Kit for ThinkMate GPU Servers

This 128GB kit contains four 32GB DDR4 2666 ECC load-reduced DIMMs built for ThinkMate GPX-QT8-24E2-8GPU servers. Each module runs at 1.2V with CL19 latency and a 2Rx4 organisation. The 288-pin form factor fits the platform's registered memory slots.

Who Should Use This and Who Should Not

IT teams expanding memory capacity in the specified ThinkMate GPU-optimised servers will find the correct rank, voltage and ECC configuration pre-validated. Builders needing standard RDIMMs, non-ECC UDIMMs, or memory for any other platform cannot use this kit.

The Deciding Specification

Load-reduced ECC DDR4 2666 at 1.2V in a 2Rx4 288-pin package is the single attribute that determines compatibility with the target ThinkMate server; any other memory type will not function in those slots.

Questions about this item

Should I choose the 128GB kit or look for a different capacity?

This kit provides 128GB total across four 32GB modules. If your Thinkmate server has enough free 288-pin slots and supports LRDIMM, this capacity will work; otherwise select a kit matching your slot count and maximum supported memory.

What does the 2666MHz speed mean once installed in my server?

The modules run at DDR4 2666 (PC4-21300) with CL19 latency at 1.20V. Actual throughput depends on your server's memory controller and how many channels it populates; the rated speed is the maximum JEDEC standard for this DDR4 generation.

Does the LRDIMM interface limit how many modules I can install?

Load-reduced DIMMs reduce electrical load on the memory bus, allowing higher densities per channel than standard RDIMMs. Your Thinkmate GPU-optimised server's chipset and BIOS determine the maximum supported ranks and total capacity per channel.
