128GB DDR5 ECC RDIMM kit

This 128GB kit contains four 32GB DDR5 4800 ECC registered DIMMs built for the Thinkmate GPX-XH8-22S4-8GPU GPU-optimised server. It targets administrators who need validated, high-capacity memory for multi-GPU compute workloads and virtualised environments.

CL40 latency and 1.1V operation

Running at 4800 MT/s with CL40 timings and 1.1V, the modules deliver the bandwidth headroom typical of DDR5 while ECC and registered signalling protect data integrity under sustained load. Capacity scales to 128GB across four slots; larger configurations would require additional DIMM sockets not addressed by this kit.

Four-module matched set

The package supplies a matched quad-channel set of 32GB 2Rx8 RDIMMs so the server can populate its memory channels evenly from day one. No heat spreaders are included, and no software utilities accompany the hardware.

Questions about this item

Will the 4800 MT/s 2Rx8 RDIMMs work alongside any existing DDR5 modules already installed in the ThinkMate GPX-XH8-22S4-8GPU?

Mixing modules of the same DDR5 generation is generally possible, but the system will run all memory at the speed and timings of the slowest installed kit; for guaranteed stability, populate all channels with identical 4800 CL40 1.10 V modules.

How can I confirm the 128 GB kit is running at DDR5 4800 CL40 with ECC active after installation?

Enter the server BIOS or use a hardware information utility in the OS; verify the reported speed shows 4800 MT/s (PC5-38400), CAS latency reads CL40, total capacity shows 128 GB across four DIMMs, and ECC status is reported as enabled or active.

What exactly ships in the box and are any extra parts required for installation?

The package contains four 32 GB DDR5 4800 CL40 1.10 V 288-pin ECC registered RDIMMs; no heat spreaders, cables, tools or additional components are included or required for standard server DIMM slot installation.
