I got it finally working again! It is definitly a BIOS-Bug.
If there is a M2 SSD (PCIe) connected and a GPU connected (PCIe) and you do a CMOS Reset, you will get a Black Screen. The integrated GPU of the CPU will also be disabled,(because that is the default behavior after a CMOS Reset if the Mainboard detects a dedicated GPU. So the Mainboard seems to detect the dedicated GPU. But all the display ports deliver no signal. Now if you shut down your system, disconnect the power cable, remove the M2 SSD, press the CMOS Button and start the system again it will run for a few seconds and restart. After that you will get a signal from your dedicated GPU and you can press F2 to get into the BIOS. Now shut down your system again and reinsert the M2 SSD. Now your system should start without problems using the dedicated GPU. TLDR:
Hope this helps the next guy having this problem. |

I asked the ASRock Support. Maybe they have an idea how to fix this.

Thank you for the suggestion!
I tried both options. 8x8 and 8x4x4. Sadly no success. :-( |

Temnis, have you tried setting Riser Card Support - Enable option in UEFI.

I have the exact same issue. I had it in the past and was able to solve it with the above mentioned method of unplugging the M2 NVMe SSD. After starting the System without the M2 SSD, the GPU was detected (NVIDIA GTX 1080). After that I reinserted the M2 SSD and the System kept running for about a year. Today I have the same issue, but the before mentioned solution is not working anymore.
Any news on this bug? I have updated to the latest Firmware already. I am pretty sure, that the problem is the detection of the M2 SSD as PCIe Device 0 instead of the GPU. Is there a way to manually set this option? |

I had this exact same problem. I installed a GTX 1080Ti into my Z370 Gaming-ITX board and I could not get windows to detect the PCI GPU. I tried every combination possible to fix it, I even tried other PSUs, and GPUs. In the end, all it took to fix it was a single BIOS reset by holding down the CMOS button on the back of the IO panel. If I had known this, it could have saved me 4-5 hours of troubleshooting.
TLDR: use the CMOS reset before trying other hardware fixes. You won't lose your saved BIOS settings. I created an account just to share this.

Very strange. I disconnected the M.2 SSD and the graphics card started working. I then re-connected it and it still works. I cannot explain it.
