today i did a new build with ryzen 5 5500 motherboard Aorus b550m elite and as memory a 1tb 990 samsung nvme, all these components support PCIe gen4, so i change from bios settings the port from auto i put it on gen 4 but opening the samsung magician program it tells me that it's connected sun a PCIe 3 x 4 port and it recommends me to connect it to a PCIe Gen 4 .0 port , clearly even via benchmark the data is very poor, I don't understand what I should do to get the drive working properly, on the bios I can't find any other settings, what should I do, has anyone encountered this problem?
