NEMIX RAM
16GB DDR5 4800 CL40 1.1V UDIMM memory upgrade for THINKMATE workstations
This NEMIX RAM module is a 16GB DDR5 4800 PC5-38400 unbuffered UDIMM validated for ThinkMate workstations. It runs at 1.1V with CL40 latency and uses a single-rank 1Rx8 layout on a 288-pin PCB without a heat spreader.
The stick suits ThinkMate desktop workstations that accept non-ECC unbuffered DDR5 UDIMMs. Systems requiring ECC, registered modules, or lower-voltage DDR5 SKUs cannot use this part.
The decisive spec is CL40 CAS latency at the standard 1.1V operating voltage. If the platform demands tighter timings or a different voltage this module will not meet the requirement.

The module is sold as a single 16GB stick; adding a second identical unit will enable dual-channel bandwidth on boards that support it.
The module runs at 4800 MT/s with CL40 timing, giving the rated PC5-38400 throughput when the motherboard trains at that speed.
Yes — it is a 288-pin DDR5 UDIMM built for ThinkMate systems and operates at the standard 1.10V DDR5 voltage.
