Hi folks,

I recently built a new PC:
ASRock B650M Pro RS
RTX 4070Ti Super
Ryzen 5 7600
32GB RAM

Upon powering on for the first time I had no output from my GPU. After some troubleshooting I found by forcing slot one into PCIe Gen 3 compatibility I was able to get display. This is obviously not ideal for a brand new PC. Wondering if anyone has any ideas of whats wrong before I return the board.

Hello,

I'm having a similar issue with an RTX 4070, the GPU won't be detected at random times, switching to PCIE Gen 3 makes it show up, I'm then able to revert back to PCIE Gen 4 (Auto), but it keeps happening it's a bit worrying...

Specs:
- ASRock B650M Pro RS WiFi
- RTX 4070
- Ryzen 7 7800X3D
- 32GB RAM (6000Mhz)

I updated to 2.01/02 when I first got the motherboard, then to 2.06 a few months ago to see if it helped (it did not).

Going to try 3.01 and report back
