IGPU assigning as primary video

Hello,

 

I have just started my array and noticed that my Nvidia 1080ti GPU is being listed in the system log, but not the onboard graphics. The bios has no option to set this and automatically detects and assigns video if a card is detected.

 

I could remove the video card and am sure the onboard will work, but adding the card will switch it back unless the configuration is changed to assign the onboard as primary.  I  have watched some videos that are dated and looking for help to point me in the right direction. I will be using the 1080ti in a win 10 vm pass-through.

 

Here is my setup:

 

Motherboard: asrock z370 taichi

CPU: intel 8700k

Video: EVGA 1080ti ftw

PSU: Corsair ax1200i

Memory: 32GB 3200MHz - xmp profile assigned F4-3200C14D-32GTZSK low profile (2x16GB)

Cooler: Noctua NH-D15.... way big outer fan was moved up some as was resting on memory

Case: Corsair 750D airflow edition

 

Cache: MydigitalSSD SBX PCIe 3.0 x2 NVMe (2x 1TB)

Parity/Disk: 2x HGST 4TB

 

This for the most part is overkill, but will be using as a plex server, gaming with room to grow.  Please let me know if there is anything else that is needed.

 

Thanks for any help

 

 

EDIT***  Need to wait for array to finish then will check cpu settings as spoke with a different tech from asrock and there may be a monitor setting to bypass auto function of video

My ASRock board (C236 WSI), has a way to select the iGPU as the primary graphics adapter and, as Squid pointed out, so does yours.  My guess is that the selection is currently set to AUTO on your board.  This option, if you have a graphics card in the PCIe slot, as you do, will result in that being treated as primary. Even if you don't have a PCIe graphics card, AUTO will cause your iGPU to function as the system graphics adapter, but, it will not load the drivers Plex needs for hardware transcoding (if you want that).  If your board has the same options mine does, you want to set Onboard as primary graphics adapter.  This is will cause your iGPU to be the system graphics adapter and load the drivers you can you use for Plex transcoding.

Thanks for response. I had to wait for array to build and then move cables in this small room which in itself was not fun. After talking with asrock several times (seems there are some knowledgeable and others not) I located the above switch and confirmed on boot up that the onboard is now switched. I checked the system by going to tools > system devices and here is my log. I am not sure if I need to do anything else to make the onboard primary, but I believe this shows both onboard and PCIe by being in different IOMMU groups. Please correct me if I am wrong. 

 

This motherboard has 2 nic's, can I bound them both for better transfer rate or is that only in a VM?
