NEMIX RAM
32 GB DDR5 kit with two 16 GB UDIMM modules at 4800 MT/s, CL40, 1.1 V, built for SuperMicro SYS-111AD-HN2 servers
This 32GB kit contains two 16GB DDR5 4800 modules built for SuperMicro IoT SuperServer SYS-111AD-HN2 and X13SAZ-F platforms. It runs at 1.1V with CL40 latency in a 288-pin UDIMM form factor. The memory is non-ECC and unbuffered for desktop and workstation use.
The single specification that determines fit is the DDR5 4800 UDIMM interface with 1.1V operation and CL40 timing. Modules must match this exact speed, voltage and pin layout to function in the listed SuperMicro systems. A different DDR generation or registered DIMM will not work.
Builders upgrading the named SuperMicro IoT SuperServer or X13SAZ-F motherboard can install this kit directly. Buyers who need ECC error correction, registered modules, higher capacities or a different DDR5 speed grade should look at other memory options.

The kit is rated DDR5 4800 (PC5-38400). The Supermicro SYS-111AD-HN2 with X13SAZ-F board supports DDR5 4800, so the modules will operate at the rated speed.
Yes, each module is a 288-pin DDR5 UDIMM. That is the standard desktop/server unbuffered DIMM layout, so it fits any board with DDR5 UDIMM slots.
The kit contains two 1Rx8 UDIMMs without heat spreaders. Populate the two slots recommended in the X13SAZ-F manual; the low-profile modules clear standard CPU coolers and the CSE-510FT-203B chassis.
