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.
 
Gigabyte released a new bios and MSI?
Update AMD AGESA 1.0.0.3 Patch A to D
Fix NVIDIA Geforce RTX 4090 PCIe down speed issue (SMU 84.79)
Add memory voltage options over 1.435V
Enhance curve optimizer range
Add iGPU overclocking option
Improve memory & PCIe device compatibility
Add ECC DIMM support
 
Links to bios 1.10 and 1.32 please

My
PCIe 5.0 x4 M.2 Connectors (M2_1 & M2_2) are not detecting WD SN850 500GB M.2 NVMe Gen4 after 7D70v12 BIOS update.

I am currently having to boot from HDD, which is extremely slow
Ok will send to you Via PM.

So you want MSI to release a Bios that has apparent bugs for some users.

At this stage, it is unknown if it is in the MSI or AMD side of the bios.
And since there are not many users who use PCIE_3 in the first place it may take time to find the problem. And it only seems to affect some hardware or boards. I don't believe I have seen any from USA or AU region yet.
 
Tried both 1.10 & 1.32 bios versions but it didn't solve the issue for M2_1 & M2_2.
Currently, I have my WD m.2 NVMe ssd in M2_3 ( PCIe 4.0 x4) which seems to be working fine.
You seem to have a totally different problem Please start a new topic.

Would I be able to get my hands on the stock BIOS as well please? Currently having issues with the PCIe 4.0 slot not detecting my Elgato 4k60pro as well

Check your PM
 
A few hours ago I bought a 7900X + a X670E Carbon Wifi. Judging by the problems I have seen on this forum (and YouTube), I think i'll wait to put the system together until AMD comes up with an AGESA update & MSI with an official BIOS update :(

MSI is waiting on AMD to release the next Bios.
so not idea how long that will be
 
I am having the exact same issue, I just picked up this board with a 7900X and can not get anything to work in the chipset slot. I updated to the newest bios as soon as I got the board installed and I was surprised when I realized that MSI does not make previous versions of the bios available. Is can someone from support please provide me with a copy of the 1.10 bios?

Yep OK will PM you the files

Thanks all the links worked fine, I installed the 110 bios and the slot functionality was restored immediately. I highly recommend that a warning is added to your bios download site and that you make previous versions of bios publicly available. I also recommend that you remind people to back up their previous bios version or update m-flash to do so automatically.

Well we kind of know that but not up to us is up to MSI
we ask for changes but not often it will happen.
After all non of us, Moderators work for MSI but just end users helping ou in the forums
 
Could I please get the link to bios 1.10? Having issues with the graphics card displaying anything right after NVIDIA drivers are installed.
