RX5700XT stability issues

I've received my new RX5700XT yesterday but I'm running into issues that which makes the card unusable. Hope you have some help or tips.

Current specs:
X370 Gaming K4 (bios P5.40)
Ryzen 7 3700X
16GB RAM (corsair dominator)

I've been using a Vega 64 before and that one runs stable with above specs. To prepare for the new card I first installed the new 19.7.1 drivers. That all went well and the Vega card was running stable. As soon as I inserted the new card, it was recognized by the driver and it installed. Then the issues happened. After a couple of minutes the GFX card switched off/on and the PC froze. After reset, boot loop, then finally back in windows for a few minutes, freeze.

So then I used DDU to completely clean the AMD drivers. Landed perfectly in the desktop with the default windows drivers. At that stage also when having a lot of stuff on the screen, same issues as mentioned earlier. Only then I could end up with a BSOD mentioning the pcie-express bus issues which could make sense without drivers. Then I tried installing the new 19.7.1. driver and during install (at 49%) same issues. Also tried resetting the bios, disable secure boot (run with CSM), but no luck. I'm now at a stage that the card is completely unusable for me.

At this stage I can think of the following things:

• BIOS issue
• AMD driver issue
• Broken card? But then maybe I also should have issues in bios or using default windows drivers?

What do you think?

Dear ReddishRat,

hmm, can't edit posts here .. only delete.
Anyways,
Do you think its an issue with the motherboard not reading the video card correctly or is it an issue with the video card not saying "Hey, you can't run 4.0 so run me at 3.0"?

if/then issue with one or the other .. but which one?

Do not use MSI afterburner to monitor, do Not even open it. Also do not use or change any watt man setting. Do not use any FPS , cpu, GPU, temp monitor software for now. They all conflict to the new RDNA architecture. If you want see the FPS, try to use the steam or u play , origin to monitor the FPS.

That is my one week experience with my RX 5700. It?™s running fine now.

Do not use any monitor software for now! Do not use any monitor software for now! Do not use any monitor software for now! Important thing repeat three times!!
