Question MSI MPG Z790 Carbon WiFi II

[IBMJunkman]

Bought because it has 5 M.2 slots. Installed 5 drives. Drive in M.2-2 is Gen 5 and the slot is PCIe 5.0. Installing Windows I am presented with the screen asking which drive I want to install to. Drive 0 thru 4. Given all the drives are the same capacity, how do I tell which one is the M.2-2 slot drive?

A 2nd question. I am putting this mobo in a HYTE Y70 Touch case. Did not think about the fact the mobo would have to drive 2 video screens. Mobo has only 1 video out. I have an old PCI-e video card but mobo does not get into BIOS setup with it installed. So, need a cheap video card that can drive the 688x2560 touch screen. Suggestions?

On my MSI B650 Edge the top slot (M.2_1) is drive 0, M.2_2 is drive 1 and M.2_3 is drive 2. The only way to know for sure is likely to remove the other 4 drives, install Windows and then add the drives back.

How old is the PCIe card? Perhaps the BIOS is set to Gen 4 for the PCIe slot and the older card is not Gen 4? You might be able to use the mobo output to get into the BIOS and change the setting, then reinstall the card. Since you have all that glass to see the system are you sure you even want to install an older or a cheap card? Especially since the Hyte case uses the vertical GPU mount. Maybe use a USB C adapter to provide the second monitor out port you need?

In the USB-C to HDMI/DP setup who/what is doing the video image creation? I understand that a video card does it. How is the signal being sent to USB-C?

The card I was trying to use is an ATI FirePro 2460. It is a PCI-e 2.1x16. Perhaps a PCI-e 4 slot can’t go back that far?

The video card still handles the image, it's just sent through the USB-C port to the adapter. I have a thunderbolt dock for my laptop that does this as well. I have 3 monitors connected to the dock and the dock is connected to the laptop via the thunderbolt (USB-C) port. I can't tell you exactly how everything works, but it does work and it works well. The display on the case doesn't require much horsepower to run the display. I think it's only a 30Hz display anyway.

I would think it would still work, but if the PCI-e slot isn't set to "Auto" it just may not work. I'm not certain that's the problem, it's just one thing you can check.

I have a newer vid card arriving tomorrow. I think part of my problem now is the mobo sees a vid card and defaults to that instead of the CPU on board video. Need to really look at the BIOS for a setting controlling that.

So you weren't connecting the monitor to the GPU when it was installed? Then that was most likely the problem.

No. I did attach the monitor to the card a couple of times. Nothing came up on the monitor. And the mobo went through all kinds of state codes. None of which made sense based on the code chart. Some were not even in the chart.

I sure hope this mobo does not consider a video card to be the primary video source when a 14900K is the CPU.

Got a Radeon RX550 video card. Installed and found the setting in the BIOS to control which video chip is primary. Have the touch screen fired up and displaying stuff.
