NEMIX RAM
Eight 96 GB registered DDR5 modules with ECC, running at 4800 MT/s CL40, built for ThinkMate HDX-XH24-52S4 servers
This 768GB kit provides eight 96GB DDR5 4800 CL40 ECC registered DIMMs built specifically for the ThinkMate HDX-XH24-52S4 high-density server platform. It targets IT teams expanding memory capacity for virtualisation, database or compute workloads on that exact system.
Each 2Rx8 module runs at 1.10V with registered buffering and on-die ECC to maintain signal integrity across all eight slots. The registered design reduces electrical load on the memory controller during sustained server workloads.
Populating all eight DDR5 channels delivers the full 768GB capacity without leaving empty slots for future expansion. The kit matches the platform's 288-pin RDIMM requirement and CL40 timing for native compatibility.

Power down the server, open the chassis, and seat each 288-pin RDIMM fully until the ejector clips click; the step often missed is populating all eight slots in the exact channel order shown in the system service guide so the 768GB kit runs at 4800 MT/s with ECC active.
The modules have no heat spreaders and no moving parts, so no routine maintenance is required; if a 96GB RDIMM ever fails, replace only that module with another 2Rx8 DDR5 4800 CL40 1.1V ECC RDIMM to keep the 8-module configuration intact.
The CL40 latency at 4800 MT/s and the 1.1V operating voltage set the throughput ceiling; sustained heavy traffic will hit the CAS-40 timing bound before thermal or power limits become a factor.
