128 GB DDR4 3200 ECC RDIMM server module

This NEMIX RAM module delivers 128 GB of DDR4 3200 memory in a single 288-pin registered DIMM. It operates at 1.2 V with CL22 latency and uses a 4Rx4 organisation built from major OEM DRAM chips. The stick is designed for Thinkmate GPX-QS4-12E2-4GPU and GPX-QT8-22E2-8GPU GPU-optimised servers.

Suited for Thinkmate GPU servers needing maximum

IT teams running memory-intensive workloads on the listed Thinkmate platforms can populate each slot with 128 GB. Systems that require unbuffered UDIMMs, non-ECC modules, lower densities or different pin counts cannot use this part.

Registered ECC with 4Rx4 organisation decides

The module presents a 4Rx4 registered ECC load to the memory controller. Only motherboards qualified for this rank configuration and voltage will initialise the DIMM correctly.

Questions about this item

Should I pick a single 128GB stick or combine smaller modules to reach the same total?

This kit is a single 128GB module; using one stick fills one slot and leaves the remaining DIMM sockets free for future expansion.

What does the 3200MHz rating actually deliver inside a Thinkmate GPU server?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency, providing the rated throughput when the platform’s memory controller operates at that speed.

Is the 288-pin RDIMM interface compatible with standard DDR4 server boards and does it limit rank population?

It uses the 288-pin DDR4 RDIMM form factor with 4Rx4 organisation; the registered design allows higher capacity per channel within the server’s memory population rules.
