NEMIX RAM
A 32 GB DDR5 4800 CL40 UDIMM module built for SuperMicro IoT SuperServer SYS-111AD-HN2 systems
This 32GB DDR5 4800 module is built for the Supermicro IoT SuperServer SYS-111AD-HN2 motherboard. It runs at PC5-38400 speed with CL40 latency and 1.10V voltage. The single 288-pin UDIMM uses a 2Rx8 organisation without ECC or heat spreader.
It fits administrators upgrading that specific Supermicro platform who need non-ECC unbuffered memory. Buyers who require ECC error correction, registered modules, lower latency timings or a different pin count should look elsewhere. The part is validated only for the named system.
The decisive figure is the 288-pin DDR5 UDIMM form factor combined with non-ECC unbuffered operation at 4800 MT/s. If the target board demands ECC, registered DIMMs or a different DDR generation this module will not work.

This module is validated for the SuperMicro SYS-111AD-HN2 (model CSE-510FT-203B) and runs at DDR5 4800 with CL40 timings at 1.1V. Mixing modules of different speeds or latencies will force all memory to operate at the slowest common settings.
Enter the system BIOS or use a tool such as CPU-Z. The memory should report 4800 MT/s (PC5-38400), CL40 CAS latency, 1.10V voltage, and 2Rx8 organisation for the installed 32GB capacity.
The box contains a single 32GB 288-pin DDR5 UDIMM (1×32GB). No heat spreader, cables, or additional accessories are included.
