768GB DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 768GB of DDR5 4800 registered ECC memory across six 128GB modules. It is built for the ThinkMate GPX-QH12-12E4-2GPU GPU-optimised server platform. The modules run at 1.1V with CL40 latency and a 4Rx4 organisation. Major OEM chips from Samsung, Micron or Hynix are used throughout.

Suited for ThinkMate server upgrades

The kit targets administrators expanding the ThinkMate GPX-QH12-12E4-2GPU to its full memory capacity for compute-heavy workloads. It is not for systems that require unbuffered UDIMMs or non-ECC memory. Builders needing lower capacities or different form factors should look elsewhere.

4Rx4 registered DDR5 organisation

Each 128GB module uses a 4Rx4 rank configuration with registered buffering and ECC. This organisation determines compatibility with the server memory controller. Verify that the platform supports 4Rx4 registered DDR5 before ordering.

Questions about this item

Should I choose the 768GB kit with six 128GB modules or a smaller capacity for my ThinkMate GPX-QH12-12E4-2GPU?

The 768GB kit provides six 128GB DDR5 4800 CL40 ECC RDIMM modules, filling six slots for maximum supported capacity in this server.

What does the DDR5 4800 speed mean for actual throughput in this server?

DDR5 4800 (PC5-38400) delivers up to 38400 MB/s per module; six channels multiply that bandwidth for GPU-optimized workloads.

How does the 288-pin DDR5 RDIMM interface limit installation in the ThinkMate GPX-QH12-12E4-2GPU?

The 288-pin DDR5 RDIMM form factor fits only DDR5 RDIMM slots; the registered design requires a server motherboard that supports ECC registered memory.
