NEMIX RAM
128 GB DDR5 ECC registered server memory kit with four 32 GB modules at 4800 MHz CL40 for Thinkmate systems
This NEMIX RAM kit provides 128GB of DDR5 memory across four 32GB registered DIMMs. It is built for Thinkmate HDX-XH24-52S4 high-density servers that require ECC RDIMM modules. The memory runs at 4800MHz with CL40 latency and 1.1V operation. It targets IT professionals upgrading compatible server platforms.
Before ordering, confirm your server motherboard has four available 288-pin DDR5 RDIMM slots and supports registered ECC memory. Check the system manual for maximum capacity per slot and total population rules. Ensure the platform accepts 2Rx8 organisation and PC5-38400 speed without requiring downclocking. Mixed-rank configurations may have specific slot-order requirements.
The modules install directly into the server's DDR5 RDIMM slots and draw 1.1V from the platform. No heat spreaders are fitted, so airflow across the DIMM area must follow the chassis design. Using all four slots populates the memory channels for maximum bandwidth. The registered buffer reduces electrical load on the memory controller, freeing it to drive larger capacities.

The package includes four 32GB modules for a total of 128GB; nothing else is required to reach that capacity.
Each module is 32GB with a 2Rx8 organisation, so four modules fill four slots and deliver the full 128GB kit.
The modules run at DDR5 4800 with CL40 timing at 1.1V, providing registered ECC operation validated for that server platform.
