RX 5700XT Not Detected

Recommended Posts

Posted · Original PosterOP

Hi all. 

 

I have a new build and my computer isn't detecting my 5700XT at all. My specs:

Mobo: Asus ROG Strix B450M 

CPU: Ryzen 5 3600x

RAM: 2x8 (16) GB 3000MHZ ddr4

2tb + 500gb HDD + 512 SSD

Silverstone 750W 80+ Non-modular

 

When I turn on the computer with the 5700xt plugged in and powered on, every light and fan turns on in the computer but I have no signal and no output to my monitor. This is with no drivers installed, for anything except a newest flash update of the Bios. When I unplug that card and throw in an old GTX 670, it boots up perfectly and runs fine and is recognized. The fans spin and the RGB lights turn on when the Gigabyte Rx 5700XT is plugged in, but nothing else happens. We tried flashing the bios, changing the PCI-E x1 lane to 3rd gen (as some people have noted fixes the issue) and tried all 3 PCI-E slots. We've come to the end of the trail and are deliberating on attempting to install the drivers with the card plugged in (but not powered by PCI/VGA cables) while the PC is running off of the 670. We also tried switching HDMI cables and even a different set of PCI/VGA power cables. Any help would be appreciated.

If it's under the 'other devices' in the device manager then it means it is not installed. If this doesn't detect at all (not showing anywhere in device manager) then it means it is not detecting. If it is listed under 'other devices' then try to install its driver, otherwise you should try reinstalling windows to check if it is detecting in the new windows or have any hardware issue in the GPU itself.

It's not listed anywhere. When we try to install the driver, it says it can't be installed because no AMD graphics cards are detected in the system.

🤔 It looks like your motherboard has an integrated GPU in it. You might have to disable it in your bios so that your dedicated GPU can take over.

Like your answer @BlackManINCIs there an option to disable it from BIOS? I am not sure about it. If this is possible, then you should go with this, because your GPU is unstable if it is not even detecting.

If it is not listed anywhere in the device manager then either your Windows got corrupted which is not detecting up your GPU or your GPU has a hardware issue. You can try to reinstall Windows to fix the Windows corruption issue. If it doesn't fix it then you'll have to forget your GPU and use the motherboard's graphic chip.
