NEMIX RAM
128GB DDR5 kit of four 32GB UDIMM modules at 4800MHz CL40, validated for the ThinkMate TWX-QS4-14R7 tower server
This 128 GB kit is built for the ThinkMate TWX-QS4-14R7 tower server. It contains four 32 GB DDR5 UDIMMs that install without tools. The modules are unbuffered and non-ECC, matching the platform's supported memory type. System integrators and IT teams can populate all slots in a single upgrade.
Running at 4800 MT/s with a CAS latency of 40, the kit delivers 128 GB total capacity across four ranks of 2Rx8 organisation. The 1.10 V operating voltage aligns with the DDR5 baseline for power efficiency. Workloads that exceed 128 GB will require a platform with higher maximum memory support.
The modules ship without heat spreaders, relying on the server's directed airflow for thermal management. No additional software, cables or mounting hardware are bundled in the package. Installers should verify chassis airflow meets the platform's cooling requirements before deployment.

The kit contains four 32 GB DDR5 4800 CL40 1.1 V 2Rx8 unbuffered UDIMMs. The system must support DDR5 at 4800 MT/s and 1.1 V; mixing different speeds, ranks or voltages may force the memory controller to run at the lowest common settings or prevent boot.
Enter the BIOS/UEFI and confirm the memory frequency shows 4800 MT/s (PC5-38400) with CAS latency 40 at 1.1 V. In the OS, tools such as CPU-Z or dmidecode will report each 32 GB module as DDR5-4800 2Rx8 unbuffered non-ECC.
The package contains the 128 GB kit as four 32 GB 288-pin DDR5 UDIMMs only. No heat spreaders, cables, screws or tools are supplied; the Thinkmate TWX-QS4-14R7 provides the DIMM slots and any required retention clips.
