If you have the opportunity, it'd be worth testing to see if your RTX 4090 works with another motherboard. If you don't have a spare, maybe try at a friend or relative's house in their rig. That way you can determine whether its the card itself or your motherboard that's the faulty component.

Well, I installed the RTX4090 into my EVGA X299 Dark which has a EVGA 850G+ power supply. The 4090 was identified and drivers loaded and worked. So I then went out and bought another power supply to put in the new rig just in case it was a bad power supply causing the issue. Nope, same issues with a EVGA 1300GT. This has to be an issue now with the Z790 Classified.

unplug NIC / kill WiFi ... you do not want Windows to try & update the machine
 
download your Nvidia driver & make a fresh install .... offline - After you check the setting I listed below
 
turn Off auto reboot in Windows

Turn Off Fast Boot in MB BIOS
 
Turn Off Windows fast startup

Nvidia patch for 40 series been installed?

I did another clean install and now back to Win11 and tried what you mentioned. As soon as Nvidia drivers are loaded same issue again. Only thing that wasn't done was turning off windows fast startup. But fast boot was disabled in bios.

My testing hasn't been as thorough as wkoger's, but I did take my PSU and 4090 out of my new build and put them into my old build which consists of a 9900k on a Z390 Asrock Taichi board. No issues whatsoever and I gamed for about an hour and a half (Cyberpunk) to make sure things stayed stable.
 
I'll probably spend tomorrow evening putting the 4090 back into the new build and troubleshooting a bit more, but right now it's looking like I'm going to return the Classified. It's not worth the headache for something that should essentially be plug and play, or at worst require minimal set up.

I feel we have bad boards or the Classified has a compatibility issue with the 4090's since I can use the classified with an older 1070 card. I submitted a support ticket yesterday with no response yet.

I have an ongoing ticket right now and so far the response has been to use the Nvidia firmware update tool, which, I'll try tonight but am not optimistic it'll matter given it did nothing for you.
 
I'm hesitant to try replacing it with another Classified as much as I like the board in general because I don't want to go through all this again. But...looking at other Z790 options, it seems like there are issues no matter what vendor you go with. MSI I've had good luck with in other recent builds for others, but I'm seeing a lot of people complaining about bad onboard audio (crackling, cutting out, etc). ASUS seems to be plagued with a lot of memory stability/compatibility. Gigabyte has a number of complaints talking about coil whine on their boards. Asrock...again, mixed bag. Regardless, all of them have issues with their Intel NIC which is yet another annoyance.
 
Just can't win lol.

You know what I'm more upset about than possibly having a bad motherboard or compatibility issues between my GPU and board? The fact that it takes 1-2 days per response when trying to get help through the service center. And not to mention you can only reply to the questions 1 at a time before you have to wait on them to respond again. At this rate it could take months to get through any trouble shooting steps they want me to do before getting the chance to RMA the motherboard. 
 
And by the way, here is another thread of my trouble shooting that has taken place over on the Nvidia forms. Hopefully the service center here will read that and be able to skip forward on some troubleshooting steps so I can get to a place where I can enjoy my investment into their products. 
https://www.nvidia.com/en-us/geforce/forums/geforce-graphics-cards/5/511860/rtx-4090-black-screen-reboot/ 
 
Yes, I'm getting frustrated and hate venting publicly but I'm struggling to simply keep it together at this point after investing over six grand into this rig and have yet to enjoy it. Really appreciate the help the form members have been offering with advice in troubleshooting.

Re: EVGA Z790 Classifield and Nvidia RTX 4090 issues 2023/03/15 18:40:02 (permalink)
I hear you, man. I've formally tried a number of things that already didn't work for you just for the sake of saying I gave it a shot.

-My mb shipped with the most recent 1.05 bios. I tried flashing to the beta 1.07 which I was hesitant to do, but did it anyways and it seemed to install OK (no power outages during or anything). Upon reboot, it hung on code A2. Basically...borked that particular bios selection. Fortunately there are two others so I switched to a different one to continue my efforts, but abandoned the idea of flashing the bios again.

-Checked the UEFI firmware using Nvidia's tool and it confirmed that my MSI RTX 4090 Gaming X Trio already has that version. Still blackscreen/reboots as you get into Windows.

-Reinstalled Windows 11 Pro onto a different NVME drive in a different slot on the motherboard. Still blackscreen and reboots as soon as you get into Windows.

-Tried installing Windows 10 Home. No difference.

-Used the newest Nvidia driver that released a day or two ago. No change.

-Tried various bios enabling/disabling options per suggestions in this thread. No change.

-Confirmed that both my 4090 and EVGA 850 T2 both work in my old system with a 9900k and Asrock Z390 Taichi.

I literally don't know what else to do.

In reading of similar problems that appear to be inherent to the Z790 chipset, it seems that people with MSI boards were able to limit their PCIe bandwidth to x8 instead of x16 and that resolved their issue until MSI released a proper bios update. These posts were from late fall so it's been several months.

As far as I can tell, there's no way to limit the lanes in the Classified bios. You can force it to Gen 5, 4, 3, etc...but no way to limit to x8 rather than x16. I already tried limiting to Gen 3 which didn't make a difference.

I updated my support ticket to include what I read about in addition to the things I tried in my prior post which didn't work. Hopefully there will be a positive response with a workaround.

Was having the same problem for weeks with no help. here my solution that help me. 
 
First Get and Old GPU not no 40 series.  plug it in. go in to bios and change "" boot mode from UEFI to Legacy/CS " restart it make sure everything running normal. 
Remove the old Video and Insert the 4090 
 
It should start Normal. after that
Updated the Nvidea
GPU UEFI firmware update tool. 
after that get the lastest driver and so on. 
 
NOW the problem is if you Updated your bios You will have to DO everything all over again...........
 
Right Now I have a D4 Error code but I shut the PC down and turn it back on and it goes away.... 
 
will have to wait.. I guess but thats How I fix it on mine.

Kosmo, thank you for assisting, After reading your post I installed my GTX1070 in place of the RTX4090 and changed Bios to legacy. But my system sees the 879 Evo that has my OS on but will not boot to it in legacy.

I was wondering about that. I've seen some motherboards have a Legacy+ type mode that supposedly can boot either type of boot directory, but I don't know how that works. I don't believe the EVGA boards do and you're boot drive is either MBS or GPT but not both so I'm not sure how those other motherboards try to do that. You need to be GPT to have resizable BAR work at all and EVGA Graphics cards (30-series anyway) needed CSM disabled before doing a vBIOS update. So some of the steps here seem like they could be questionable or only work on certain hardware (I'm not sure if 4090's are as restrictive on the CSM setting for vBIOS updates).
 
That said, Lee had mentioned in this thread a suggestion to enable CSM to see if that helped you boot, which should really accomplish the same thing Kosmo was suggesting for the most part. 

6Q6CPFHPBPCU691 is a discount code anyone can use.

Welp, I thought I had found a workaround finally but ultimately no luck.

Read a few different posts about the issue being between the Z790 chipset and RTX 40 series and how it has to do with the PCIe slot being at x16. The suggestion was to limit the slot to x8 and that it worked for people.

So, unfortunately the Classified bios doesn't let you manually change the number of lanes a slot can use. My thought was to put another PCIe device in the bottom slot to force the top slot to x8. This part worked...in the bios it showed the gpu slot at Gen4x8 and the bottom slot at Gen2x4 (I used an elgato cam link pro here).

It seemed promising at first. I was actually able to be in the windows environment for longer than before, but not long enough to do anything. The first few times it froze and the next few times it did the usual black screen reboot. Tried going back into the bios and disabling resizable bar and enabling csm but...no go.

In my service ticket it was said that they are looking for a fix. It will either be by them or Nvidia till then I have an expensive paper weight. Asked to RMA the board they said they don't think the board is bad as this is likely a compatibility issue since the board works with other cards and the 4090 works with older boards. $6,000 computer paper weight....

As an update here, we've been able to reproduce the issue on the Z790 Classified in Gen4 x16 mode.  The DARK does not appear to be affected.  We're still root causing the issue.
 
On the Z790 Classified, it seems to work fine in Gen4 x8 mode in both slots, just not in Gen4 x16.

Unfortunately, the second part of what you said didn't work for me. I had read about that possible solution elsewhere and tried it last night by putting another PCIe device in the other slot and the BIOS confirmed that my primary slot was Gen4 x8. However, I still ran into the blackscreen/reboot cycle.

That's great news that it's been replicated by the team. Now that they see what it's doing i n real time, it will make troubleshooting it much easier. This gives me hope. Thank you for the update!

What happens if you test your 4090 in the second x16 slot?  Sorry if you mentioned that already.

It's not possible for me to test that unfortunately. I have three slots of space at the second slot and my card is nearly a four slot card.

Unfortunately the card wont fit into the bottom X16 slot without a riser cable. Using a Corsair iCUE 7000X RGB Full Tower ATX case that limits me to only cards that are 2 wide and not 3 wide like the RTX 4090.  I am planning on getting a riser cable though as I was surprised by the actual weight of the RTX 4090 and don't trust any motherboard to support it long term.

As an update here, we've been able to reproduce the issue on the Z790 Classified in Gen4 x16 mode.  The DARK does not appear to be affected.  We're still root causing the issue.
 
On the Z790 Classified, it seems to work fine in Gen4 x8 mode in both slots, just not in Gen4 x16.



Unfortunately, the second part of what you said didn't work for me. I had read about that possible solution elsewhere and tried it last night by putting another PCIe device in the other slot and the BIOS confirmed that my primary slot was Gen4 x8. However, I still ran into the blackscreen/reboot cycle.


What happens if you test your 4090 in the second x16 slot?  Sorry if you mentioned that already.




Picked up the thermaltake TT Premium PCI-E 4.0 Extender (Riser) so I could test out the second X16 slot. Same issues once drivers were loaded.

My understanding is that the issue has been root caused and they are verifying a solution.  No ETA, however.

This new Bios update 1.11 seems to have resolved my issue. Thank you,

Still has some issue below.
1. Still could be boot in Legacay mode only.(Nvidia GPU UEFI Firmware Update Tool 1.2 done.)
2. Still cannot install the intel HD Graphics driver.(which in the EVGA original usb or download from intel site both.)(The driver's Error code 8)
3. Still cannot use processor graphics to display. I use i9 13900k. (with Intel UHD Graphics 770.) 
4. Still cannot use the intel 2.5G lanport. 
 
Now I just can use my 4090 in legacy mode...
Is that normal?

Could you start a new thread for these issues and provide more information about each of these?  This is very different than what others have reported.
