MSI MPG X670E CARBON WIFI - PCIe slot no longer works after BIOS update

Hi,

At the launch of AM5 I purchased an MSI MPG X670E CARBON WIFI for myself along with a Ryzen 7 7700X and 2x 32 GB DDR5-5600 RAM. For the first few months it has been running pretty smoothly with no major issues.

However last weekend I decided to update the BIOS to the latest version (7D70v12) and while it offers some nice quality-of-life improvements, it did also introduce one major issue for me. In PCIe slots 2 and 3, I have installed two capture cards: an Elgato Game Capture 4K60 Pro MK.2 and an Elgato Game Capture HD60 Pro, respectively. I use these side-by-side for different purposes. After the BIOS update, the HD60 Pro capture card in the PCI_E3 slot from the Chipset is no longer being detected by Windows. There are no errors, no unknown devices in Device Manager, it's like the card isn't there at all.

I've already tried various things: updating drivers for the motherboard including the Chipset drivers, installing the latest drivers and software for the capture cards, updating Windows 10 to the latest version and installing all optional updates. I also reset the BIOS settings to the defaults and checked with that. None of those things solved the problem. At this point I'm very sure it's not a software or settings problem.

To eliminate the possibility of a failure with the capture card itself, I also swapped around the cards around so that the HD60 Pro is in the PCI_E2 slot. And sure enough: now the HD60 Pro is being detected again while the 4K60 Pro card is no longer visible in Windows. So I'm very certain that the problem is with the PCI_E3 slot (the only slot to come from the Chipset and not from the CPU) and it cannot be a coincidence that the problem appeared immediately after updating the BIOS. My guess is that this BIOS version introduced a bug in the Chipset firmware that causes the attached PCIe slot to fail initialization.

I would like to downgrade the BIOS again to the version that came preinstalled on the motherboard (version 110) just to see if that solves the problem, but that version does not appear to be available for download anywhere.

P.S.: I also noticed that after the BIOS update, the Sleep option disappeared in Windows. This bug is already covered and acknowledged in a different thread on this forum and I've confirmed that disabling A-XMP in the BIOS makes the Sleep option reappear, so this seems to be unrelated to my PCIe slot issue described above.
 
It is the Intel Wigig card for the Vive wireless. I have no idea what's on it, as it is difficult to find any meaningful specs online.

If your card works, then it seems to be a question of how well it works. My card is obviously more sensitive to minor faults than a USB card, which might work around any problem that will render mine useless. I wouldn't be surprised if the people in here with capture cards start noticing similar problems.

Again, I find it weird that they fixed it and then immediately broke it again.

I get the same problem not often about once a week if that Just hangs on the boot. It seems to have something to do with the SSD not activating as have noticed when it does that I have no Harddrive activity LED showing on PC case
So you think all is fine about it ? And one more question. When i enable memory context restore i get BSOD. After I disable it works fine.
I am just using expo 1 profile.

One do not put words in my post that are not there I never said I was fine with it
Do I think it is fine NO I don't I want it fixed but I want a lot of things. most of which will never happen.

Before you enable Memory Contex Restore Enabal Powedown in Ram settings

All this still correct

I've got a EZDIY-FAB NVME M.2 PCIe 4.0 Adapter in slot 3 working fine with 7D70v186. Not sure I will upgrade to 7D70v18 if it breaks slot 3 again.
 
Now also on official 7D70v186.
All fine so far with my usual settings:
- PCIe_3 is working with the SoundBlaster
- Expo 1 (6000MT/s CL36 2x16GB)
- WiFi, BT, HD Audio, iGPU off
- TDP on 120W Settings (of the X3D CPUs) -> good Aircooler has no issues keeping CPU at <91°
- PBO All Core CurveOptimizer -20
- VDDCR_SOC 1200mV (instead of EXPO-default 1300mV)
 
Yes, although I now have a 4090 Suprim Liquid X [912-V510-011].
The problem has been consistent irrelevant of which GPU I've used. My third slot was working fine with the 4090 and one of the older BIOS updates.
Did you keep the Copy of the Bios you were using that did work

Would have been V175

According to an earlier post of mine, it should be stable on 7D70v17. I didn't download any of the special BIOSes you provided. If you'd like, I can downgrade and double check to be sure.

Edit:
After hours of troubleshooting, I have found out that the older BIOS wasn't as stable as I first thought. It crashes less, but it's still not as good as using PCIe_2.

I downgraded to v17 and tried every possible combination of PCI speed, 8x4x4x, with and without EXPO enabled, made sure my chipset was up to date. Nothing works. I then upgraded back to v18 and ran the same tests again. It's the same across the board. Considering that other people are not experiencing problems, the only conclusion I can draw is that my specific card does not like to be routed through the chipset PCI lanes. Perhaps this is connected to the Ryzen troubles Vive wireless users were experiencing back in 2018/19, but I don't know if that was ever solved.

I will PM you 175
 
does the '00' problem whern rebooting resolved???

the problem is still there under latest 186.

clear cmos
power on
'15' for some time
then stuck on '00'

then power off
and power on
del into CMOS
exit CMOS without anything changed
stuck on 00

Unknown as is not a problem I had but no one has mentioned it recently
 
if I use default 4800 freq, no this problem,
if use EXPO at 6400, will raise it,
event down to 6000, it is still there.

but aida64 test memory 6400 pass.

I have the code 00 on reboot issue with my Ryzen 7600x with the MGP X670E Carbon, but I also have this issue on a MSI Pro B650M-A WiFi board. It has the reboot problem regardless whether RAM is set to EXPO or 4800MHz JEDEC defaults.

However setting Memory Context Restore and Memory Power Down along with manual RAM timings (manual EXPO settings), I can get about a 10 second boot on the Pro B650-A WiFi board. So while it hangs on reboot and won't sleep, at least it boots fairly fast.

My Ryzen 7900x doesn't have a problem with reboot or wake from sleep on either motherboard... so it's possible I have a weak 7600x CPU, it might qualify for RMA.
