Capacity and compatibility

This 768GB kit contains twelve 64GB DDR5 4800 ECC registered DIMMs validated for THINKMATE TWX-XS8 tower servers. The modules are built with major OEM chips and run at 1.1V with CL40 latency. They suit IT teams expanding memory in qualified Thinkmate platforms for virtualization, database or compute workloads.

Thermals and power

Each module operates at the standard DDR5 voltage of 1.1V without a heat spreader, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping maintain signal integrity across all twelve slots. Power draw scales with capacity and rank configuration under sustained server loads.

Package contents and support

The box delivers the full 12x64GB kit ready for installation in compatible Thinkmate TWX-XS8-24S4 or TWX-XS8-14S4 systems. NEMIX RAM stress tests every module under load before shipping and backs the kit with a lifetime replacement warranty. Technical support is provided by experienced IT staff who specialize in enterprise memory upgrades.

Questions about this item

How do I install the 12 DDR5 4800 RDIMM modules in the ThinkMate TWX-XS8 tower server, and which step is most often missed?

Power down the server, open the chassis, and insert each 64 GB 288-pin RDIMM into the correct DIMM slots per the system manual; the step most often missed is populating the slots in the exact channel order required for 12-module operation.

What maintenance or replacement will the 768 GB DDR5 ECC registered kit need over its service life?

The modules have no heat spreaders and no moving parts, so no routine maintenance is required; replacement is only necessary if a module fails, which is covered by the manufacturer's lifetime replacement warranty.

What is the first limit reached under sustained load with these CL40 1.10 V DDR5 4800 RDIMMs?

The primary limit under sustained use is the CAS latency of CL40 combined with the 1.10 V operating voltage, which determines the maximum stable throughput before timing errors appear.
