Hi all,

I just upgraded from an Asus Z170-A with i7 6700 to a 12600k with MSI Z690 Carbon WIFI. For some reason, the GPU is not getting detected and the VGA light remains on. The GPU in question is an AMD RX6900XT Red Devil from Powercolor. I've tried switching back to the Z170-A and confirmed the GPU still works. Some stuff that I've tried is limiting the PCIE speed to Gen 3 and 4, but that doesn't seem to solve the issue. I've also tried using both PCIE slots on the motherboard but to no avail.

Any help would be appreciated, thank you!

can you remove the GPU and use integrated graphics card only (from rear panel HDMI/DP port) to see if system can really boot up?
sometimes when debug LED stucks at VGA, it has something to do with storage/USB pen drive. If VGA debug LED still remains on, remove USB pen drive or HDD/SSD to see if it helps.

Hi there,

I appreciate the response, but I've already RMA-ed the motherboard. But to answer your question yes, it can boot up with integrated graphics and go into windows/bios just fine. Even on a windows level the OS doesn't detect the GPU at all

Hi, I had the same problem, which I fixed after 2 days. I hope to help people with the same problem.
The new units did not detect my GPU. My components are: Z690 GAMING X DDR5 and my old GTX 660 :). When the computer was started, 5 short beeps sounded and the screen did not respond. The BIOS version is F5.
What I did:
1. Removed GTX 660.
2. Installed Windows with the built-in GPU.
3. Changed the settings in the BIOS: Advanced Mode -> Miscellaneous -> CPU PCIe Link Speed = Auto to Gen3 and PCH PCIe Link Speed = Auto to Gen3.
4. Turned off the computer and insert GTX 660.
5. Started the PC using the built-in GPU.
6. Installed the drivers for GTX 660.
7. Restarted and restored the settings in the BIOS as they were before.
8. Removed the HDMI cable from the built-in GPU.
Everything works! :)

I would say it had more to do with your GPU being to old to support UEFI that the Motherboard would have been looing for.

I just saw your solution, I'm looking in my bio and I don't see a miscellaneous section after going into advanced.

Hey guys
Created an account here to post my update.
I had the same issue with 1080ti
My solution was
1. Updating the bios
2. Change from DisplayPort version 1.4 to 1.2 on the monitor
3. Change to lower refresh rate at the monitor

Hope it helps someone

An update, after a couple of days I’m still having issues with Samsung neo g9 and 1080ti

1. Changing uefi to csm seam to help
2. Setting DisplayPort 1.2 on boot.

Even if I do both of these I still have encounter these issues.

about half of the times on reboot screen won’t detect and I have to power off change display settings and trya couple of times until it works.
It’s very frustrating
I’m on the carbon z690
