I am building a new pc

B650I Auros Ultra
R7 7700x
32 gigsGskill flare x5 ram
RTX 4080
Sabrent m.2

I have windows 11 installed, no issues with the initial setup, but problems started once trying to boot into windows..

If I boot off the 4080, the PC will freeze with a black screen after the bios flash screen. If I boot off the igpu it goes right into windows.

First thing I did with troubleshooting was to update motherboard firmware. I have also tried removing sata drives as well and running mem86 which tested fine. Ram is obviously brand new as well None of which helped, after doing more digging I found the nvida firmware update, ran that and it told me the GPu already had been updated.

More troubleshooting, if I boot with the display port plugged into the igpu and after boot plug it into the 4080 everything appears to work sometimes, other times I will get no input found....

Another interesting note is that it does not appear that the audio drivers where installed with the other gpu drivers....

The 4080 works fine on my desktop and my 2080 ti works fine on the new PC…

Looking for opinions on what might be causing this issue….

Cheers!

I've heard some new boards have compatibility issues with RTX 4000, maybe update the BIOS ? Look in the update log if something like this is mentioned.
 
Try setting video output in bios to discrete(not igp).

Thanks for the response! Unfortunately that is the first thing I tried, that and then the GPU firmware which was supposedly "updated" already....

I am digging into the riser cable, this is a small form build and the riser cable is 3.0.... sure it should still work but going to see if I can hard set the PCI-E slot to make sure its set to 3.0 since the cable is 3.0..

dont whant to set it' said:

That is a thought, the GPU should at least get me into bios as well if that doesn't work... I took it apart for the minute to measure the riser cable... but a new 4.0 cable that will fit, need about 300 mm and 90 degrees, cost as much as a new case, lol.......

I'd bet that is exactly what your problem is. If you're on a PCIe 4.0 or 5.0 motherboard, have a 4.0 GPU, and a 3.0 riser cable, you need to set the PCIe slot to 3.0

Since 2080ti is 3.0 it explains why it would work with the 3.0 riser cable without troubles

Well the bios is set to AUTO, but its exactly what I am trying right now.....

Weird thing is the board as 1 PCI-E slot, yet in the bios it has 2 settings

PCI-E Slot Link Speed
PCI-Ex16 Slot Link Speed

Not sure why but I am setting them both to Gen3 and disabling the igpu....

Update:

So I set both those slots to GEN3, an disabled the igpu and Windows loaded!!

Not ready to say this is nothing but luck, the first time I loaded into Windows after format it DID load into Windows 11 and worked fine until I started to run Windows updates....

I thought I might have powered it down during updates by not paying attention, and then when rebooting is when this issue started....

I did a Windows reinstall but this issue has been persistent ever since, so at least for now its working though, going to have to do some stress testing now I suppose......

This includes the M.2 slot speed. You should leave it on auto. Changing it can nerf your ssd.

Gigabyte has a unified manual for their BIOS instead of a manual for each model so anything that is not in your BIOS you can just ignore.

So I should just set it for the x16? Let me try that one and see how it goes!

Ok so that worked no issues, x16 still set to Gen3.... I do have a feeling that having that igpu still enabled was the root cause though.....

Odd thing here is the pc isn't detecting audio drives even though I have already installed the Nvidia suit....

Actual operation mode is subject to the hardware specification of each

I think so. This part of the description should mean that the individual setting for each slot should override this setting. So setting the PCIEx16 to GEN 3 should override the Auto in the main setting. But keep Auto for the rest. Problem is some parts of these manual and bios things have strange English that we can only guess what it really means.

the iGPU has nothing to do with this. everything will work fine if you enable the iGPU. it was solely the PCIe gen of the single slot your GPU plugs into (the one labeled x16) being set to auto instead of 3.0

actually, I should rephrase that....the REAL smoking gun problem is the PCIe 3.0 riser cable. and the only solution to have a working system while using that cable is to manually negotiate the gen speed to 3.0 in UEFI

Well I just tried reinstalling the nvidia drivers and still I am getting no Audio drivers found... But I also installed the motherboard audio drivers and that is not being detected either....

The more I think about it the more this makes 100% sense....

Think of it this way, the 4080 was sending a 4.0 negotation signal to the board, so the board said ok lets roll with gen4 and sets that speed...

The cable is only allowing 3.0 so the signal is not a 4.0 data transfer but a gen3 while the board is expecting a 4.0 data transfer...

The board gets confused and does not know how to handle it once it starts to boot into Windows...

Cheers mate, hope this thread helps other people who are doing small form builds and got a 3.0 PCI-E cable.
