I here to report a problem that seem to affect quite a few people on reddit i found. It's only on AM5 and 4XXX series card it seems.

All AGESA after 1.0.0.7c have a problem with PCIEX LINK Speed being stuck at 1x after a Windows Shutdown.

I confirmed that with CPU Z and in game as my 4090 lock to 250-270WW, i get stutter and much lower fps.

This can be fixed by rebooting the session, but that's annoying.

I started to have this problem back in November when i updated to AGESA to ComboAM5 1.1.0.0 , at that time i didn't knew what was the problem.

Every single AGESA after 1.1.0.0 have this problem but not 1.0.0.7c and 1.0.0.7b (didn't try a older bios)

I did the following in the current 2 weeks (each of those i done multiple windows shutdown and reboot at least 10x each bios) :

Flashed to AMD AGESA 1.1.7.0 = windows shutdown, turn computer back on PCI LINK 1x, reboot PCI LINK 16x ok

Flashed to AMD AGESA  1.0.0.7b = windows shutdown, turn computer back on PCI LINK 16x ok

Flashed to AGESA to ComboAM5 1.1.0.3 = windows shutdown, turn computer back on PCI LINK 1x, reboot PCI LINK 16x ok

Flashed to AMD AGESA  1.0.0.7b = windows shutdown, turn computer back on PCI LINK 16x ok

 Flashed to AGESA to ComboAM5 1.0.0.7c = windows shutdown, turn computer back on PCI LINK 16x ok

So it's 100% bios issue

One user on reddit had the same problem (different motherboard), i have him tested 1.0.0.7c witch had fix he's 1x too on windows cold boot. He doesn't have the same brand of motherboard. Both of us have B650 (i have B650E)

So right now i'm stuck at 1.0.0.7c, witch work fine, but i can't move from this bios otherwise it's annoying.

i flashed 1.2.0.0A on Friday and it's been gold so far on my end. No 1X Link, 16x all the time so far today, i've been doing couple of On and off cycle

Yeah,

had the exact same problem with my GPU. When i cold booted, it would show up x1 and then after a restart it would show up x16 all the time. Fixed it by your advice downgrading to an Bios Version which uses AGESA 1.0.0.7c.

Since then the issue never appeard after 10+ cold starts. I have an Ryzen 7 7800x3D, Aorus RTX 4070 Super Master, Aorus B650 Elite AX V2 for reference. Tried both the F1 and F2 Bios of my Mainboard, which both have AGESA 1.0.0.7c  and had no Problem anymore. As soon as i flash a newer Bios with an higher AGESA Version i get the issue again.

I am having the same issue with my pc. I have a Ryzen 5 7600x, Galax RTX 4060 Ti and a MSI B650m Mortar Wifi.

Any bios beyond AGESA 1.0.0.7c The pcie link goes to 1x or 4x after a cold start. After restarting the system the pcie link goes back to X8 as normal

The same problem with Ryzen 7 7700 + RTX 4060

Tested on BIOS with AGESA 1.2.0.0a Patch A - PCIEX LINK speed stuck at 1x.

The only thing that helps is changing the PCIe x16 slot configuration from "Auto" to "x8x8" (this method is not very suitable for RTX 4090 since there is no "x16" option in the slot settings)

Forgot to answer, I also flashed the Bios with 1.2.0.0A because of ur comment and Problem is solved, all the time 16x since a week. So they probably finally fixed it.

[Macaxeira]

I tested with 1.2.0.0a Patch A too, same issue happening again.

[Lys1]

You probably have to wait till other Bios Versions get released, which might fix it for you.

It seems the problem has been fixed in AGESA ComboAM5PI 1.2.0.2

PCIe/GFX Lanes configuration set to Auto, PCIe link works at x8 (after a cold start and after reboot)

Tested on:

• motherboard: ASRock B650 Livemixer (Ryzen 7 7700), BIOS version 3.08
• video card: ASUS DUAL-RTX4060-O8G

Jumped on this thread after finally locating what was causing the issue.

AsRock B650E Taichi Lite + 9800X3D + 4090. Running AGESA PI 1.2.0.2a

Two issues:

- More often than not, the PC hangs out on restart. It apparently works fine, but after shutting down it won't boot again, remains stuck doing something, no video signal and no POST. I have to shut down through the button and boot it again for it to work.

- When restarting, again more often than not, the GPU works at PCIe 1 speeds, which results in much lower FPS than intended. I tried various ways of solving it, like disabling iGPU, to no avail. So far it seems that only cool booting fixes it. Once it boots at PCIe 4 it remains fine until another restart.

So, any clues?
