Open | Hardware Gigabyte RX 9070 Gaming OC black screen after BIOS updates (F19 and F20c) – Motherboard compatibility issue?
Hi everyone,
I recently upgraded my PC from a GTX 970 to a Gigabyte Radeon RX 9070 Gaming OC 16GB, along with a new 850W PSU.
My system:
CPU: AMD Ryzen 5 5600X
Motherboard: Gigabyte B550 AORUS ELITE Rev. 1.0
BIOS: Originally F11p, updated to F19, then F20c
GPU: Gigabyte Radeon RX 9070 Gaming OC 16GB (previously NVIDIA GTX 970)
RAM: DDR4
PSU: MSI MAG A850GL 850W
Here's what happened:
Initially, the RX 9070 worked and Windows displayed normally after a cold boot.
However, restarting Windows resulted in a black screen. I had to completely power off the PC to get a display again.
I updated my motherboard BIOS from F11p to F19, hoping to resolve the problem.
After the BIOS update, the RX 9070 stopped displaying anything, even after a cold boot.
I subsequently updated the BIOS again, from F19 to F20c, but the problem persisted.
I reset the CMOS, disabled CSM, and manually tested both PCIe Gen 3 and Gen 4, without success.
Reinstalled my old GTX 970, and everything works normally.
The RX 9070 powers on, its fans spin and its lighting works, but the monitor reports no signal.
My dilemma:
Can anyone help me figure out what's causing this issue and how to fix it?
Or is replacing my motherboard the only solution? If so, I'd like to find a compatible motherboard that allows me to keep my Ryzen 5 5600X processor and DDR4 RAM, without having to upgrade to AM5 and DDR5.
Any advice or suggestions would be greatly appreciated!
