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.

Just for anyone who may have a similar problem; it turns out it wasn't a specific M2 SSD brand problem, but a SATA SSD instead. When no SATA SSDs are connected everything works just like it should - super stable and smooth. Also, boot times are great!

Unfortunatelly, after few days without problems, the M2_1 (Sasmung 980Pro) boot problem is back. It seems it may be a Samsung problem after all (or MSI MPG x670e Carbon Wi-Fi problem); the only option is to replace the Windows M2_1 with MSI M2 SSD and see what happends.

Sorry would have to Disagree
Not when I have Six Sata-lll drives and Four M.2

The Lexar SSD is in M.2_2

I will just use 4 MSI M480 M2 SSDs and then it should work. There is something going on between Samsung's M2 SSDs (as a Windows boot drive) and MSI's MPG x670e Carbon Wi-Fi motherboard specificly... they just don't "like" each other.

Do you mean a SATA-SSD in an m.2 slot or SATA SSD connected to the SATA-Ports?
The later I can't confirm at least a general problem, as I also have a wild mix of PCIe4/PCIe3 in m.2 and some SATA SSD on the SATA-ports. Maybe really your SATA-SSD has some issue and is messing up the system?

SATA SSD in any of SATA ports, but it turns out the boot problem with M2_1 slot is still there even without any SATA SSDs in any of SATA ports connected. So far it seems MSI MPG x670e Carbon Wi-Fi (for yet unknown reasons) DOES NOT like Samsung M2 SSDs.

I will test M2_1 slot with MSI's M2 SSD and see if that fixes the problem. I mean, it should. If not then MSI's mobo is just faulty, or its bios is broken, still. In that case I will have to look into other brands like Asus.

There is a temporary fix; have to go into bios each time from a cold boot. Better than randomly going into a black void loop of "not sure what's happening".

sorry for taking forever for a REPLY, but out of curiosity would you possibly know what 10GB SFP network adapter would work with my mother board? as i decided i no longer need extra ports but a 10gb connection now

Any in this list will function correctly

And... turns out it wasn't Samsung's M2 SSD problem :( Now I have all MSI M2 drives and cold boot still has a problem. I'm out of ideas by now... The last option is to try with default bios settings.

is that all of them that were tested? as the only one i can find that is SFP based is the intel x710-T2L which is a expensive SFP based 10GB adapter

Looks like that is all they tested or that passed testing as the list is the same for a couple of other boards

This problem is a right pane in the rear and seems random as if one will be affected by it

Error codes or logs would sure as hell help but it seems none get generated

So far it still works, takes 10sec more to get to the boot screen, but it works. I will let it run (MCR:Auto and EXPO 1) for a few weeks like this to get a consistent result base and afterwards will try to set MCR:Enabled. #exclusion method

Hello, after a long time I would like to share my latest updates. I tried all of them from 7D70v172 (Beta version) bios to 7D70v18 version bios but I was not satisfied. The most stable bios for me was 7D70v16 version and I have been using that version for a long time.

I just upgraded to 7D70v1C 2 days ago. I am using 2 XPM and 2 EXPO supported ram and only the XMP option is active on the BIOS. When I turned on XMP, the Bios time was around 66 seconds even though it was up to 6200Mhz.

Without using XMP and EXPO, I set the RAMs to 6000Mhz from the OC settings on the bios and set the voltage to 1.35. I had to make 2 more settings that you have already shared in the forum.

Power Down Enable = Enable
Memory Context Restore = Enable

After adjusting these settings, I saw that the Bios time dropped to 18-19 seconds.
I haven't had any problems for now and I will continue to use it like this for a long time.
You can see my old and new bios times in the attachment.

Just a feedback,
Currently at 7D70v1F and most of the things is fine.. even the igpu showing up when its disable is still acceptable except the stuck at 00 from a reboot/warm boot still persisting.
[Power Down Enable / Memory Context Restore = Enable ] solves my Long boot time issue and so long I do not select XMP profile but manually select speed and key in the timing/voltage to the same as whats in the XMP. Cold boot to OS takes under 20 seconds but warm boot still stuck at 00 error for the past few revision including the betas.

I have read around but did not find any specific post on this 00 error for a warm boot (ie from reboot OS) so just asking aloud if anyone has a good way to fix this behavior.

Guys, my pc was working OK but with a problem with the cpu running hot on idle. Updated the BIOS to the last one.

All went well until the first boot. Entered windows but now I'm stuck in a black screen after post and the MSI logo. No error. Code on the debug. It shows the temp 53/54. Num lock light is not working either.

What can I do?

If you update the Bios you need to set it all back up again
it is a right pane as you can not load your saved setting from the previous bios
