MPG X870E CARBON USB-C DisplayPort sometimes works, sometimes doesn't

[davydov.ily14e402cf]

I bought this motherboard a week ago (MPG X870E CARBON). It looks it is working really strange sometimes. I have display DELL P2723QE and I connect this display to motherboard using usb-c. My processor is AMD 7950D3X. So, the problem is the next: Some period of time the display works correct and all additional usb ports work good. But after restart or the long period of idle it doesn't work at all, the display doesn't work and all ports don't work. The restart doesn't help. But it can start to work spontaneously. Can some out help to understand how to resolve this problem, please?

For example, it started to work for now. I tried to charge some device, it was the bluetooth speaker and after when I tried to connect my display, it spontanueosly started to work

Are you using the latest BIOS version? https://www.msi.com/Motherboard/MPG-X870E-CARBON-WIFI/support

If you already do, i'd open a ticket with MSI.

1A10. Should I update to 7E49v1A15(Beta version)? I'm worry about stability.

I can confirm 7E49v1A15 is pretty stable and would recommend upgrading. I was actually getting random freezes in earlier versions, which seems to have been fixed with 7E49v1A14. There are still plenty of BIOS bugs though...

Any odd behaviour that could be due to a BIOS bug, especially on a newly released board with an immature BIOS, you should always test the latest beta BIOS first. If it's really fixed in there, then anything else you try would be a waste of time.

If you buy a brand new board that has just come out, you're an early adopter, wether you knew it or not, and sometimes you have to put up with things like this. MSI can only test so much in-house, but once the board starts being sold, that's when all the different configurations can uncover bugs. The early adopters will report those bugs back to MSI, and MSI can hopefully fix them. Within a few months, the BIOS matures and the biggest bugs should be taken care of.

Upgrade the BIOS to 7E49v1A15(Beta version) didn't help

Would you be able to test a different monitor over USB-C? Also can you try this monitor using HDMI?

I attached the video, where I showed that the display is working by hdmi, but isn't working by usb-c.

This display works perfectly with my macbook pro.

This display works perfectly with my macbook pro.

Of course it does, Apple is quite mature having all accessories over Thunderbolt
So it may indeed be some form of a bug. I'll see if I can find more about this.

Maybe you have a link to new bios for testing? Because nothing has been appearing lately.

 

[davydov.ily14e402cf]

And again after some time, the display started to work using the USB-c cable.

If you lower the resolution, will the behavior improves?

Hi
So my contact tried to replicate your issue, but wasn't able to. They tried different model though as they don't have dell on hand. So it could be anything, from incompatibility related issues through damaged components/devices.

 

[davydov.ily14e402cf]

The problem was related to the USB-C cable. I've played with several cables and found that it works stable with the specific USB-C cable.

Thanks for coming back. Is it any specific brand that worked for you? Might help others if anyone comes looking.
