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

Updated successfully last week.
Still having issues , the update helps but screen still works about 20% of the time.
Usually it turns black when rebooting, but when starting the computer cold it shows the bios.

It starts working when I’m in Windows.
But to enter the bios I usually still have to set the DisplayPort version to 1.1.

Have you also updated motherboard BIOS to 7D30v17? (released on 2022-07-12)

Same problem here. Brand new Z690 ek x, right out of the box and updated with the latest bios and all drivers. My 1 yr old 3080 was pulled straight out of my working old system, and is unrecognized.

have you installed the 3000 series firmware update?

also, does the system give GPU EZ debug LED no matter which PCIe slot you install the GPU?
Unfortunately haven't been able to because my old system was scavenged for this build. I'll probably have to commit to reverting to my old board to try the update, but the EK X variant is water cooled so it's a bit of a chore. My only other system runs proxmox, but I'm not sure about doing a bios update through a VM.

No debug LEDs, regardless of slot I install it in. I've tried the various bios settings mentioned with no luck. The card fan doesn't even run.

I did get the board to recognize an old RX580, so at least I've ruled out a damaged board slot. It just doesn't seem to know the 3080 is present. I suppose it's possible the 3080 died during the hour it was sitting on my desk during the swap, but I think that's unlikely. I guess I'll know soon enough when I tear this system back down.

Seems we're both having extremely similar issues, only difference is I'm using an Asus b660i motherboard.

I have a good feeling you'll find that your 3080 perfectly working on any motherboard less than 12th gen. Just like I am.

Here's my own issue:

Can't get my RTX 3080 FE to work on any Asus Rog 600 series motherboards

I can't seem to get a display output from my RTX 3080 when it's connected to any Asus 600 series motherboard.

I've tried the GPU on three motherboards so far:

1. Asus ROG Strix B660i gaming wifi (Doesn't work)
2. An Asus Z690 motherboard (Doesn't work)
3. An MSI Asrock Z390 (Works)

But older GPUs seem to work perfectly on my B660i mobo, got a gt730 working perfectly.

Here's what I've tried so far:

1. upgraded my Rog Strix B660i Mobo to the latest bios version,
2. changed bios settings to use PCIE slot as the primary display (for some reason it always goes back to auto),
3. checked my power supply (I'm using an 850w psu)
4. tried the display id firmware update (but says the gpu is up to date)
5. Reset the CMOS many times.
6. Tried enabling CSM in bios
7. Downgraded my OS from Windows 11 to 10




**Specs of my pc**

Intel 12700k

64GB DDR5 5200mhz

Nvidia RTX 3080 FE

850w power supply

Well, it turns out it's likely my 3080 after all. Seems odd that it died the instant I installed it, but I bought a new 1000W corsair PSU making my old system complete, and the 3080 doesn't work in either one. It's in for RMA currently. Apologies for cluttering up this thread.

Well that sucks

May have been some residual static that killed it.
Or one of the golden fingers was damaged some times a slight scratch is all it takes to damage them
