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.
 
Sound Blaster X EA 5 Plus on PCIE 3 not working - bios 7D70v174(Beta version).
Does anyone know where I could find to disable the cpu fan error? I have my aio plugged into the pump. But I don't see the option to disable it in the fan page. It just showed up after updating to 7D70v174
Umm OK, last time I looked today bIos was still a 172 I will shoot a quick message over to Our contact about it.
Please list what AIO you have
And just what is the error you are getting
And Im guessing the patch For PCIE_3 may not have been included for some reason.

Thank You for your help. I have the nzxt z73 aio. The error I am getting is cpu fan error please check. Configuration says cpu fan fail warning control set to enabled but I can't find the option to disable it. First time seeing this coming to this new bios.

YA I have asked and will load up the bios soon and see if I can find it

Very odd With this bios attached images to show. If I turn on ftpm 2.0 in the bios it enables fan warning. But disabled it doesn't. When I upgraded to this bios also ftpm 2.0 was unchecked. I've been on windows 11. Windows is still saying tpm is still enabled

YA something is not correct I zeroed out my CPU fans but kept the pump going and no warning at all about the fans not running
fTPM is enabled but showing disabled on the main screen
Yep PCIE-3 is also not patched yet well I was hoping for it to happen

As you can see fTPM is enabled

Same, I don't have a fan warning setting either.

On another note, after the BIOS update to 7D70v174(Beta version) I have manually set SOC to 1.2v just to be safe given this is a beta. I did notice that it is hard coded to 1.3v and doesnt fluctuate, which is why I changed it. This time around, I have set vcore to auto from a fixed number which use to be 1.23v and VPP voltage has been lowered to 1.8v from 1.95v.

Please note TMP is enabled by default with BIOS 7D70v174 please for now do not enable it on the main screen as it may cause a error

OK so I can replicate the error
I will let our Contact know about it

Oh, this is bad. It seems like MSI doesnโ€™t know how to merge 2 branches of code.
Oh they know now but somehow it got left out.

I'm just going to wait for a few more comments and then send a detailed email
I have popped them a quick message about it for now.
 
Sound Blaster AE 9 on pcie 3 not working bios 7D70v174(Beta version) when will it be working? i bought a mainboard with 3 pcie lanes for a reason. and it wasnt cheap in my world.

Have all ready informed our contact if you need it working I have a bios you can use till then


And believe me that board is not cheap no matter where you live

I guess MSI think that the mainboard is still too cheap to fix the long ongoing problem as a matter of priority. I am glad that I have not installed the 1.74 as this would be a waste of time...
 
Wow, and I though it was bad in the US at $439.99.
Going with current exchange rate and tax @ 10% GST as there is no Import duties on PC stuff should be about $720

MSI stuff is getting expensive in Australia for some reason AMD god board is well over 2k

Thanks for the info on motherboard prices in Australia.

I have heard back from our Contact

Please note TMP is enabled by default with BIOS 7D70v174 please for now do not enable it on the main screen as it may cause a error

The fTPM causing a CPU fan error will be addressed with a patch

No eta yet on when Our Contact is trying hard and working on a fix for it.

To avoid this error from happening please use the Security setting to turn fTPM on or off

As for PCIE_3 the patch to remedy it not being detected has not been included in BIOS 7D70v174 as it is still undergoing validation and testing.
So please be patient and if you do need PCIE_3 working I can supply a test Bios if necessary
Via PM
