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.

OK will add you to the list of Problems with PCIE_3
So much for hoping it was a one-off



Please check PM.
 
I got the same issue, now the compute is crashed as I have the PCIE SSD on slot 3, please PM me the link of bios v1.10 as well, thank you!

Thank Alan, unfortunately both of them cannot work properly.
I tried to figure out what' happen, reduce the peripherals, disable some functions in BIOS, but still not work.
Now what I found is most of the interfaces that comes from chipset can't work properly, include sata, usb, m.2 and PCI-E3.
Do you have any tool to check the health of the X670 chipset? Or does it mean my motherboard is broken?
EDIT
==================

The good thing is the performance of 1.32 looks much better than old version, very smooth

Not a problem will send you both can you please report back the results? we need to know what is and is not working to help get it fixed.
With more input from end users the easier it may be to fix.

Any chance we get a bios soon with High Voltage Mode enabled and/or tREFI customizable?
Also OC profiles are not saving any setting from the pbo menu.
That's got to be annoying if you testing the OC setting
I will add it to the list MSI contact.

Can you do a Cmos reset with PSU unplugged
Unplug PSU and hold down PC power button for a few seconds to drain power then press the Reset Cmos on back of IO for about 20 seconds.
Also Use Bios 7D70AMSv110 for now
See if this helps

Thanks for the Info
It all helps
 
My pcie_3 is inserted into the m2 card, and it is operational in bios131

So just what is working and how is it set up
and what is the rest of your hardware
>>Posting Guide<<
MSI is trying to track down the problem it seems it may be certain hardware that is the problem but more testing and getting hold of that hardware in Question takes time.

This is one of the main reasons I'm so instant on Hardware info makes and models,
The more accurate the info the more chance of MSI getting their hands on the correct hardware to test.

CPU: AMD Ryzen 5 7600x
RAM: Kingston 16GB*2 DDR5-6000/CL36 FURY Beast Black
Graphics: MSI VEGA56 (placed in slot PCI_E1 )
Power supply: Antec 850HCG
SSD: KINGMAX 256GB*2 TEAM T253 1TB*2 WD20EZRZ 2TB*1
M2_3 WD BLACK SN750SE 512GB
PCI_E3 M.2 PLEXTOR PX-256M8PeG
Win10 pro 22H2
BIOS recognizes M2_3 as PLEXTOR PX-256M8PeG. In fact, M2_3 is WD BLACK SN750 SE 512G. PCI_E3 is PLEXTOR PX-256M8PeG.
In BIOS E7D70AMS.131 the hardware runs normally

Please send me bios E7D70AMS.131
It is not recommended that you flash E7D70AMS.131. E7D70AMS.131 is modified for the problem that Kingston 16GB*2 DDR5-6000/CL36 FURY Beast Black cannot use EXPO and The problem that the USB keyboard and mouse function can be woken up normally after hibernation.
