If an AMD Ryzen 5000 series processor will be used, please check the paired motherboard whether is featured with AMD X370/ B350 chipset and the PCB version is marked rev1.0. If so, the rev1.0 PCB needs to be reworked by local RMA to improve the compatibility of the above processor support. Other PCB versions (i.e., rev1.1 and beyond) would be no problem for the above processor support.
