System-Specific DDR4 ECC RDIMM Kit

This NEMIX RAM kit provides 256GB of DDR4 3200 registered ECC memory in two 128GB modules. It is built for THINKMATE GPX-XT6-24S3-8NVLINK GPU-optimised servers that require registered DIMMs with error correction.

Registered 4Rx4 Modules at 1.2V

Each 288-pin RDIMM uses a 4Rx4 organisation and operates at 1.2V with CL22 latency. The registered buffer reduces electrical load on the server memory controller, while the lack of heat spreaders means the modules fit tightly spaced DIMM slots in dense chassis.

Verify Server DIMM Population Rules

Before ordering, confirm the THINKMATE GPX-XT6-24S3-8NVLINK supports 128GB 4Rx4 RDIMMs and the maximum capacity per channel. Check the motherboard manual for required slot population order and whether mixed-rank configurations are allowed.

Questions about this item

What DDR4 speed and PC4 rating does this registered ECC RDIMM kit run at?

The kit operates at DDR4 3200 with a PC4-25600 data rate, delivering 25600 MB/s peak bandwidth per module.

What physical slot and pin count do these 128 GB modules require?

Each 128 GB module uses a 288-pin DDR4 RDIMM form factor and fits standard server DIMM sockets keyed for registered memory.

How are the two 128 GB sticks installed for correct population on a ThinkMate GPU-optimised server?

Install one module per channel in the farthest slot from the CPU, following the motherboard manual's population order for 4Rx4 registered DIMMs.
