I've got an RTX 3080FE gpu that works on a MSI Asrock Z390 motherboard.
I've tested the same gpu on two Asus 600 series motherboards:
1. Asus ROG Strix B660I Motherboards (My motherboard)
2. Asus Z690 Motherboard (A friend's)
These two motherboards don't detect my gpu, meaning there's not display output, I also have a feeling it's not just output, on my motherboard it doesn't even detect a PCI Device.
Plugging the HDMI and Display port to the integrated graphics works perfectly.
YET, the both motherboards work with older GPUs, I've managed to obtain a GT730 (which mind you, only gets power from the PCIE slot). This is without any bios hijinks or hardware changes, it's the exact same configuration and it works out of the box.
Here's what I've tried so far:
- upgraded my Rog Strix B660i Mobo to the latest bios version,
- changed bios settings to use PCIE slot as the primary display (for some reason it always goes back to auto),
- checked my power supply (I'm using an 850w psu)
- tried the display id firmware update (but says the gpu is up to date)
- Reset the CMOS many times.
- Tried enabling CSM in bios
- Tried forcing the pcie version to gen 4 and 3.
- Downgraded from windows 11 to 10, also tried running arch linux.
- Downgraded from display port 1.4 to 1.2
- Downgraded the bios the earliest stable version.
From the research i've done so far, this doesn't seem to be isolated to Rog motherboards. Here's a similar situation on the MSI Forum:

- Intel 12700k
- 64GB DDR5 @5200mhz
- Nvidia RTX 3080 FE
- 850w power supply
What i need help with is figuring out the bios settings to get this GPU detected till a bios update arrives (At this point i believe it's a bios flaw) or a pathway to applying for a refund.
Tnanks for the help.
