System-Specific DDR5 RDIMM Kit

This NEMIX RAM kit provides 768GB of DDR5 4800 ECC registered memory across six 128GB modules. It is built for the THINKMATE GPX-XS8-24S4-4GPU workstation where maximum capacity and error correction are required.

Straightforward DIMM Installation

The 288-pin RDIMMs seat in standard DDR5 slots without tools or heat spreaders to clear. Alignment notches prevent reversed insertion, but the 4Rx4 organisation means the platform must support quad-rank registered DIMMs or the system will not post.

Steady Throughput Under Load

Registered buffering and on-die ECC keep data integrity intact during sustained compute or virtualization workloads. The 1.1V operating voltage and CL40 latency maintain consistent bandwidth without the voltage scaling needed by consumer modules.

Questions about this item

How can I verify the 4800 MT/s speed and CL40 latency are active after installing the 6x128GB kit?

Enter the system BIOS or UEFI and confirm the memory frequency reads 4800 MT/s with timings set to CL40; the registered ECC modules will also report corrected error counts if the platform logs them.

What ships in the box and do I need extra parts to populate all 24 slots?

The kit contains six 128 GB 288-pin DDR5 RDIMM modules totalling 768 GB; no additional memory is required unless your configuration calls for more than six modules.

Which capacity should I choose if the workstation has 24 DIMM slots and I want to fill them evenly?

Each 128 GB module is a 4Rx4 registered DIMM; buying four of these 6-module kits provides 24 modules for full population across all slots.
