System-Specific DDR5 ECC RDIMM Kit

This NEMIX RAM kit supplies 32 GB of DDR5 memory as two 16 GB registered DIMMs built for the ThinkMate GPX-XS8-24S4-4GPU workstation. It targets IT professionals and system builders who need validated ECC registered modules for that exact platform.

Registered DDR5 4800 with CL40 latency

The modules run at DDR5 4800 (PC5-38400) with a CAS latency of 40 and operate at 1.1 V. Registered buffering and on-die ECC add command-address overhead that limits raw throughput compared with unbuffered memory, and the CL40 timing further reduces peak bandwidth for latency-sensitive workloads.

Verify workstation model and slot population rules

Confirm the system is the precise ThinkMate GPX-XS8-24S4-4GPU workstation before ordering. Check the motherboard manual for approved DIMM population order, maximum registered DIMMs per channel, and whether 1Rx8 modules are supported in your desired configuration.

Questions about this item

Should I choose the 32 GB kit or a single 16 GB module?

The 32 GB kit provides two matched 16 GB modules for dual-channel operation, which doubles memory bandwidth compared to a single stick.

What does DDR5 4800 CL40 mean for real-world workloads?

The 4800 MT/s transfer rate with CL40 latency delivers high throughput for ECC-registered server tasks while maintaining data integrity.

Is this module compatible with standard DDR5 motherboards or only registered RDIMM slots?

This 288-pin DDR5 RDIMM requires a motherboard that supports registered ECC memory; it will not work in consumer UDIMM slots.
