192 GB DDR5 4800 ECC registered server memory kit in six 32 GB modules for ThinkMate tower servers
This 192GB kit contains six 32GB DDR5 4800 registered DIMMs built for ThinkMate TWX-XS8-24S4 and TWX-XS8-14S4 tower servers. It targets administrators who need maximum supported capacity in those specific platforms. The modules are ECC registered with a 2Rx8 organisation and run at 1.10V. Buyers who want non-ECC memory or a different form factor cannot use this kit.
Each module operates at 4800MT/s with a CAS latency of 40 cycles. The registered design places a register on the command bus so the memory controller sees a single electrical load per DIMM regardless of rank count. This stabilises signal integrity when all six slots are populated under continuous enterprise workloads. Builders who need lower latency timings than CL40 will not find them in this part.
The sticks run at the standard DDR5 voltage of 1.10V and ship without heat spreaders, relying on server chassis airflow for cooling. Registered DIMMs typically draw slightly more power than unbuffered equivalents because of the onboard register. Systems with restricted airflow or passive cooling may not dissipate the heat adequately. Users who require heatsinks or active cooling on the modules must look elsewhere.

Each module operates at 1.10V with a CL40 latency; DDR5 RDIMMs at this voltage typically draw only a few watts per DIMM under load, so total heat output for the 192GB kit remains low enough for standard server airflow.
The TWX-XS8-24S4 or TWX-XS8-14S4 must provide six free 288-pin DDR5 RDIMM slots and a CPU or chipset that supports registered ECC DDR5 4800 memory.
Yes, provided the existing modules are also DDR5 ECC RDIMMs; the memory controller will train all populated slots to a common speed and latency, so matching rank and voltage helps stability.
