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.
 
Sorry, I worded the sentence wrong.


From this e-mail I understood that there is a new test bios. If so, please send it to me for testing.
I wish you a good day.

Good afternoon! Can you tell me if everyone has a problem with the long boot of the computer? The approximate loading time is 30 minutes. Maybe who knows how to reduce the time?

Alan J T. Bios E7D70AMS.171T1 i already had and tested. From the e-mail you gave, Iiunderstood that there is a newer bios test. If you receive it, please send it to me for testing.

Welcome to AM5 :rolleyes:. Literally everybody has that prob, it used to be longer than 30 seconds. Go team blue if you still have the chance, this platform is immature and riddled with bugs. Unless you have the patience to wait it out and play a betatester for a while :)

From what I have heard is undergoing validation and no idea how long it will take. For now, just use the 7D70v171T1 in need PCIE_3
 
The testing BIOS seems to be working well so far. Installed without issue, Windows booted right away, the capture card in PCI_E3 is detected and working correctly, XMP profile works as well as the Memory Context Restore feature, SoC voltage locked at 1.250 V and with my usual PBO settings. Everything has been running stably, including a short gaming session.

Lets hope they can use the positives from this BIOS in the next one! How is the space between your GPU and the device in your PCI-E3 lane?
 
Hi All

I Have been giving new Bios to fix the PCIE 3 Problem

BIOS 7D70v175
As well as a couple of other fixed SOS implemented
The CPU Fan fails when selecting the TPM switch in easy mode is fixed


As per usual if you wish to try this bios Please let me know and will PM you the link.

Hi Alan,

Thanks for this - I would be keen to test.

Quick question, is warranty void if we use this?
