x670e motherboard causing massive stuttering

Hi! I have a problem with my motherboard. So, i have my GPU in the MOBO top PCIe slot, and randomly on restart or boot up, my GPU will run at PCIe x16 1.1 or 2.0 instead of x16 4.0, and this causes stuttering to the point of the system being unusable, and the only way to fix this is restarting the computer until my MOBO decides to let the GPU run on x16 4.0. I have tried forcing the PCI-E1 slot to only use gen4 (in BIOS settings) but the problem still occurs. On the other hand, if i force it to run only on gen3, then all is fine and it never changes to any other gen on restart. What can be the cause of this problem and how can i fix it? I've been struggling with this for a month now and i've run out of ideas. I even replaced my GPU once thinking that was the issue, before realizing it was from the PCIe.

Specs:
MOBO: MSI x670e gaming plus wifi
GPU: Gigabyte 4080 super gaming oc
CPU: Ryzen 7 7800x3D
SSD: Lexar M.2 PCI 4.0
RAM: 2x16GB Patriot Viper 6000 series

Using latest BIOS version (7E16v19), i've tried other versions as well but no change..

Can anyone help?

I have almost the exact same build and I'm experiencing stuttering as well!

Specs:
MOBO: MAG x670e Tomahawk Wifi
GPU: MSI 4080 Super
CPU: Ryzen 9 7950x3d
RAM: Corsair Vengeance 4x16

What do you mean by the GPU is running at x16 1.1 instead of 2.0? How would I check this? And did you find anything else that might be causing stuttering?

GPU is running on PCIe x16 1.1 instead of 4.0, not 2.0. You can check this in GPU-Z. And i found no solution thus far..
 
How would I check this?
CPU-Z

GPU-z is different than CPU-z. :-)
Check the network driver version you are running. If it's 10.73, downgrade to 10.72. Not sure how many combinations this effects but the 10.73 drivers caused massive stutters and lag that are gone now that I've downgraded.
Someone also mentioned downgrading fixed their PCIe slot being stuck at 1.1.
The PCIe bus DOES go to lower power mode when not needed, and will show 1.1 in GPU-z but should boost when in a game.

Yeah sorry, mb haha.
You can view it when you test the PCI-E in the bus interface, in the ? icon. Mine goes from 1.1 idle to 5.0 when doing the test.

Hopefully we'll hear back from OP. I'm literally sitting in front of the machine I'm building for my wife running OCCT extreme with a 6400 3:2 memory overclock on Hynix M die 7200 RAM with tRFC at 625, and undervolting the CPU all core -10 with the boost clock set to +50 to start. Memory is rock stable but dropping the main timings any further causes a bluescreen on boot instantly. :) So starting to play with the CPU boost and undercoat. A24 on the carbon wifi 870. WAY better experience than when I built mine.
Gonna pop A24 on mine soon then might start playing with men overclocking/undercoating on it again with the new BIOS.
I still contend the LAN 10.73 driver was 90% of my problems.

Hi, the network driver downgrade made no difference unfortunately. PCIe still stuck on 1.1 or 2 on most boot-ups.
 
Dang, it doesn't change when running a game?
Nope, the system can't even run a game at 5 fps when the PCIe is stuck on x16 1.1/2.0, it is literally unusable, everything lags and stutters, the mouse moves with like 2 fps while sitting on desktop . I have to keep restarting until it runs on 4.0 for it to behave normally.
 
Ugh, sorry friend. Kind of out of ideas at this point. Don't know why, but ha e you made sure to get the newest chipset drivers for the board? Are you using an m.2 slot that is sharing bandwidth with the pcie_1 slot?

Does the same problem happen even after clearing the CMOS and setting the BIOS to default(no pbo, co, expo) values ?

Yup, latest drivers on everything. I am using an m.2 slot but this motherboard doesn't share any bandwith between M.2 slots and PCI-e slots, like the x870e does for example.
 
Yes, i have cleared CMOS multiple times and have tried BIOS default settings, to no avail..
The bandwidth dynamically adjusts between x1.1, x2 and x16, depending on the system's state. This is unlikely to be the direct cause of the issue.

Try turning off Re-bar and integrated graphics in the BIOS, or set the power management mode to "Maximum Performance" in NVCP.

Also, try restoring power settings to default in the Windows Control Panel.

This is just my suggestion, but disconnect the Ethernet cable, completely uninstall the graphics driver using DDU, and see if the desktop still runs at 2–5 FPS. If it still runs at 2-5 FPS without the GPU driver, it could be a hardware problem.

If it's due to a physical connection issue, you could try cleaning the slot with something like BW-100 cleaner and then reinstalling the card.

I had a similar problem with a Gigabyte GPU before (the Windows desktop was running at 10-25 FPS with nothing open, and games were at 5 FPS). The Gigabyte engineer told me that sometimes, perfectly working GPUs can lag severely in Windows 11 for no clear reason. They suggested testing with Windows 10 to see if it made a difference. I found it too annoying, so I ended up just replacing the GPU, and that solved the problem.

The bus lane config stays at x16, that's not the issue, the PCIe gen version is the one causing the problem (It's not only staying at x16 1.1/2.0 on idle, no, even in games it stays like that, it's like it is stuck, it never changes until i restart the computer). Turning off re-bar does not help, i have tried the power management mode on max performance and all other options. Power settings have been restored to default, yes. Issue still persists with a clean uninstall of the graphics drivers using DDU as well. The PCIe slot has been cleaned properly, no debris or anything else that might cause a connection issue. I also have tried Windows 10 and it behaved the same. And replacing the GPU a 3rd time now isn't even a possibility as there's no 4080 supers (or 5080's for that matter) in stock for any retailers in my country.

If it's not even an NVMe issue, it seems like you've tried almost everything (I've seen bad NVMe drives cause problems that seem unrelated). The only thing left is to send the motherboard for RMA. I hope the problem gets fixed.

I also have A24 on my x870 tomahawk and it works ok... Only problem i have is that EXPO doesnt work right now :S
