NEMIX RAM
A 32GB DDR4 3200 ECC UDIMM module with CL22 latency, 2Rx8 organisation, 1.2V operation and 288-pin layout for SuperMicro X12STL-IF systems
This 32GB DDR4 3200 ECC unbuffered UDIMM is built for the SuperMicro X12STL-IF platform. It runs at 1.2V with CL22 timing in a 2Rx8 layout. The module uses major OEM chips from Samsung, Micron or Hynix and carries no heat spreader.
Buyers needing ECC memory for a SuperMicro X12STL-IF system will find this module a direct fit. It is not for platforms that require registered or load-reduced DIMMs. It is also not for systems limited to lower speeds or non-ECC memory. Builders wanting RGB lighting or a heat spreader should look elsewhere.
Installation follows the usual DIMM slot procedure: align the notch, press until the clips lock, and verify seating. The main issues are mixing ECC with non-ECC modules or populating slots in an order the board manual does not support. Always power down and ground yourself before handling the module.

Yes, the module is a 288-pin DDR4 ECC UDIMM, so an available DDR4 UDIMM slot on the X12STL-IF is required.
The board will run all installed DDR4 ECC UDIMMs at the lowest common speed and timings; mixing CL22 2Rx8 with other ranks or latencies is supported but may lower overall performance.
Check the BIOS memory information or run a hardware utility such as dmidecode or CPU-Z; it should report 32GB, DDR4-3200, ECC enabled, and the correct part number.
