PCIE slots 2 and 3 should be fine for the video cards, the only slots where both can run with 8x PCIe lanes.

Advanced\AMD PBS\PCIe x16/2x8 switch to 2x8 forces that, if it will not be applied automatically.

But the bios will use only one card for output, which is normal i guess.
The second card will be accessible under the OS and you have to install a driver for it.
If you are using windows, you should see the card in the device manager and even a pop up for installing the driver.

Thanks for the suggestion, but that did not seem to work. I don't think I had modified anything else in the BIOS before, but I did a reload defaults, and then made the settings change you suggested.

Same result. I'm not sure it matters, but I currently have the GT 1030 card in what I would consider the primary PCIE slot (PCIE slot 2). Perhaps tomorrow I'll switch the cards around, just not enough time tonight.

I am also going to try using the very bottom PCIE slot (PCIe slot 5) ... basically going to try all sorts of video card/slot combinations.

If you or anybody else has any other suggestions, I'm open.

Again, thanks for the suggestion.]]> Fri, 22 Nov 2019 09:36:42 +0000 https://forum.asrock.com/forum_posts.asp?TID=12940&PID=70299&title=asrock-x370-taichi-dual-video-cards#70299 https://forum.asrock.com/forum_posts.asp?TID=12940&PID=70298&title=asrock-x370-taichi-dual-video-cards#70298 Author: Ray62

I am attempting to use 2 video cards on my X370 Taichi MB.

NVIDIA GTX 1050
NVIDIA GT 1030

Specifically, I am running the unRAID system, and would like to use the GTX 1050 for hardware transcoding (PLEX and HandBrake) while using the GT 1030 for hardware pass-thru to a VM or just for a GUI on the system itself.

My problem is that with both cards inserted, it seems the system does not recognize the GT 1030, even before loading any OS. I cannot get any POST video on the GT 1030, no matter which slot I put the 1030 in -- I am using PCIE slots 2 and 3 for the video cards.

Using one card at a time, everything works perfectly, no matter which slot I use for the single card. When I insert the 2nd card, I only get video on the GTX 1050.

Thoughts?
