NEMIX RAM
Adds 192 GB of DDR5 4800 ECC registered memory in a six-module kit for ThinkMate tower servers
This 192GB kit contains six 32GB DDR5 4800 registered DIMMs built for ThinkMate TWX-QS8-14E4 and TWX-QS8-24E4 tower servers. Each module runs at 1.1V with CL40 latency and 2Rx8 organisation. ECC and registered buffering protect data integrity in mission-critical workloads.
Operating at the standard 1.1V DDR5 voltage, the modules draw minimal power and generate low heat without a heat spreader. The registered design reduces electrical load on the server memory controller, helping system fans run quietly during typical enterprise workloads.
Every module is rigorously stress tested under load before shipment to verify reliable operation during extended compute tasks. The 2Rx8 rank layout and ECC correction maintain throughput and data accuracy when all six slots are populated for long-running server applications.

Power down the server, open the chassis, and insert each 288-pin module into the DIMM slots specified in the ThinkMate TWX-QS8-14E4 or TWX-QS8-24E4 service manual, matching the recommended population sequence for six 2Rx8 registered DIMMs.
No routine maintenance is needed; the modules have no heat spreaders and run at 1.10V, so replacement is only necessary if a DIMM fails ECC correction or the server's memory diagnostics report uncorrectable errors.
The CAS 40 timing and 4800 MT/s data rate set the baseline memory throughput; sustained workloads that exceed the 38400 MB/s peak bandwidth per channel will encounter latency-bound stalls before any thermal or voltage limit appears.
