So,
I just installed my B450-F Gaming II successfully. I managed to install W10 and update the bios, etc.
After a restart, the mobo isn't responding anymore?
What happens when powering up:
- Usual booting. Error-Indicating LED's show up as usual.
- Then, all 4 LED's turn off, indicating there is NO error...
And, worst of all. No screen output.
Things i've tried:
- I've tried IGPU and EGPU as screen output, but nope. I've even removed my GPU.
- Used a Jumper for BIOS-Reset. But that did not help.
- I removed the CMOS-Battery for a couple of seconds (15). Bot nope.
- Currently Re-flashing the mobo via the FlashBack button, this helped. It resetted the bios. But, it's a temporary fix.
When connecting my RX580 through a PCI-E 1x Riser. (Which worked before!), it goes into mad-lad mode.
I'm not sure why it stops working afterwards. In the Motherboards BIOS-Settings i disabled External GPU Screen-output, so it uses my AMD 3000G's iGPU, for screen output.
This is what i want:
Connect a total of 3 RX580's through 3 PCI-E 1x risers.
Update [19-10-2021 16:12 GMT+1]:
Reflashed BIOS Again. Managed to connect 2 RX580's to PCI-E 1x via BUS 1 and BUS 3. When i connected the 3rd RX580 to BUS 5 (the third PCI-E 1x slot), it broke down again to the endless No-LED's and no screen.
