chillr88 Posted November 20, 2017 Share Posted November 20, 2017 Hello everyone, Does anyone have any experience with the asrock 970 extreme4 and GPU passthrough? I've done everything under the sun (I think) and I only get a black screen, I think maybe that mobo just has issues. Quote Link to comment
serguey bubka Posted November 26, 2017 Share Posted November 26, 2017 Hi! I have a 970pro3 r2.0 and I can passthrough a gtx970 and a hd6670 with no problems at all. Did you turn on the iommu and vt-d settings on bios? Sérgio. Quote Link to comment
Micaiah12 Posted December 29, 2017 Share Posted December 29, 2017 Hey guys sorry to steal the thread. I am having an issue with the exact combo. I am trying to get an rx480 passed through however unraid thinks iommu is turned off. I have looked everywhere in the bios and the only thing I can find related to virtualization is the amd virtual desktop setting. Any ideas? Quote Link to comment
chillr88 Posted December 29, 2017 Author Share Posted December 29, 2017 I never had an issue finding IOMMU on the 970 ext4, I promise it's there but I can't recall on what screen in the bios. Maybe update your bios? Is it the same model mobo? My issue did resolve. I didn't specify but at first I was trying to run with only one video card. I then dug up an old pos card to use as the host card and used the 7950 in the second slot but it still didn't work. I was actually trying to run everything headless and used an old vga monitor to make these changes. I then used an hdmi monitor and voila, works just fine headless and with steam in home streaming. I think maybe the card (via vga adapter) just didn't like vga? I may try to go back to one card, it's really crowded in that case... Quote Link to comment
