I have a RX 570 run with ASUS Prime A320m-K and Athlon 200GE,I noticed my performance was less than some benchmarks I watched so I used GPU-Z,it showed that my RX 570 run at PCI-e 3.0 x4 even at full-loaded,I tried reseating my graphics card but nothing changed.Do I have to clean the PCI-e lane too?My motherboard has only 1 PCI-e 3.0 x16 lane.Any suggestions?
