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.

We have a bios you can try

READ THIS FIRST



I'm waiting on info to try and get Release bios
Thanks. It seems the link you posted just refers back to this forum thread? I'm not receiving a download for a BIOS file in any case.

Was that download supposed to be the Beta BIOS (7D70v123) that was available from the Support site a short while ago? If so, I found that I still have a copy of it that I downloaded some time ago but never installed.

Either way I would very much appreciate it if you could track down the launch BIOS for this motherboard, as I am more confident that that will work and not cause any problems over a Beta BIOS.

Please see PM for assistance.

Can you report the results back to this topic, please?

Thanks

Thanks for the quick assistance!

I tried installing the V1.24 BIOS first, which unfortunately did not solve the problem.

Just now I downgraded the BIOS to the V1.10 version you sent via DM and sure enough, both capture cards are now working again! So it does seem that the recent BIOS updates are the culprit somehow.

Again thanks for helping out, and I hope you'll be able to find the root issue and fix it for the upcoming BIOS updates.

A few more observations, which may or may not be relevant:

These capture cards have an HDMI passthrough feature that allows you to view the incoming signal on a monitor even if the capture card is not in use, so long as it is receiving power. This passthrough was also not working after the V1.20 BIOS update, suggesting that the PCI_E3 slot may not have been supplying power to the card at all.

After the V1.20 BIOS update, I noticed that HWiNFO64 reported that SecureBoot was not enabled (showed as red in the Summary screen) even though SecureBoot was enabled in the BIOS and I didn't change this from the default setting. Now that I've downgraded back to V1.10, HWiNFO64 is once again reporting that SecureBoot is enabled and working correctly.

Have received confirmation from MSI that they could replicate your problem with BIOS
And they recommend you use new
BIOS as this worked when tested with your configuration.
I will PM you the link

I tried the new BIOS and unfortunately it did not solve the problem for me. As soon as I had updated, the capture card in slot PCI_E3 went missing again. I double checked that I was running the correct version (V1.32) in both HWiNFO64 and the BIOS itself afterward. For the time being I've downgraded back to V1.10 again.

I just signed up to write I am also having a problem with NO card detected on PCI_E3.
In my case the card was this card:

The card works fine in PCI_E2

I am also on BIOS version: 7D70v12

This needs to be solved ASAP and someone from QA needs to explain or be educated in testing for the complete failure of an entire PCI_E slot going unnoticed. This complete QA failure is definitely going in my review.

Does anyone have the 1.10 BIOS handy?
Pathetic that one has to choose which breakages to deal with (as 1.10 has breakages as well).
