My PC won't post when two graphics cards are plugged in

Recommended Posts

I have two graphics cards: a Red devil RX580 and a Sapphire Pulse RX580. My PC will work normally with either card plugged into either of the two PCIE slots in my motherboard. However, when I plug both cards in the PC will turn on but I won't get a display output from either graphics card. I have an Asus Prime B350 Plus (Windows 10 64 bit/ BIOS: American Megatrends 0805 2017-06-20), a Ryzen 5 1500X. If you need anymore details, let me know. Thanks for your help!

Might be worth it to update the BIOS as it's rather outdated. In fact, the latest BIOS came out today!


PC Specs - AMD Ryzen 7 2700X MSI X370 Gaming Plus 16GB Corsair Vengeance LPX DDR4-3000 - GTX1070Ti FE 600p 256GB & M550 512GB & 860 Evo 500GB Fractal Define R5 CM V550 W8.1 Pro

BIOS update worked! I feel so dumb for not doing it before. That said, AMD settings now refuses to open because  "I need to plug in an AMD card" I'll try newest adrenaline software but let me know if you have suggestions

Stuff works now but Lesheen's article is worrying. I have the option of returning thte pulse card and the 850W psu I bought, I can keep my config as is because a mobo upgrade in the future will be beneficial and I may experience some benefit now or I can upgrade my mobo now (not interested in that right now really). What are people's thoughts
