I have a MPG Z490 GAMING PLUS motherboard. I'm using it as my gaming pc / mining. When I set pcie gen in bios, I have 1,2,3, auto options. Well I'm trying to set to gen 1, to try and solve crashing issue while mining. But whatever I would select, it would stay at gen 3. My main gpu will change, but not my secondary. Tried all slots. Any suggestions? I'm using gpuz to see what gen it is running while on windows.
