System-specific DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 128 GB of DDR5 4800 registered ECC memory in two 64 GB modules. It is built for THINKMATE HDX-XH24-52S4 high-density servers that require registered DIMMs with error correction.

Verify registered ECC support and slot count

Confirm the motherboard accepts 288-pin DDR5 RDIMMs with ECC and registered buffering. The system must run at 1.1 V and support CL40 timing. Ensure enough free DIMM slots exist for both 64 GB modules in the desired configuration.

Fills two RDIMM slots in a compatible server

The pair occupies two 288-pin DDR5 slots and provides 128 GB of registered ECC capacity for memory-intensive workloads. It leaves remaining slots open for further expansion within the platform limits. No heat spreader is included, so airflow across the modules must be adequate.
