ASRock X370 Taichi Dual Video Cards

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   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?

	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.

	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.

	Maybe worth to read for using 2 GPUs: Ryzen mainboards: selection of primary graphics device https://www.reddit.com/r/VFIO/comments/65oi0r/ryzen_mainboards_selection_of_primary_graphics/
