To install PIMAX VR glasses, I need to turn off the IGPU. I set the menu in the BIOS to "IGPU disable", then I save and the system restarts. After the restart, the IGPU is back to "UMA_AUTO" How can I switch off the IGPU permanently? What surprises me is that when I save, I don't get show what changes I've made as usual. BIOS is up to date to version 1.18 (last staple version). Windwos and NVIDIA GPU driver are up to date, too.

It wouldn't save for me either until I updated bios to 1.20. Not sure if a newer bios version is available for your board, but you may want to try that. IGPU may also be disabled in Windows device manager. If all else fails, open a support request at: https://tw.asrock.com/events/tsd.asp" rel="nofollow - https://tw.asrock.com/events/tsd.asp Good luck ------------- ASRock X670E Steel Legend (ABA159EAF581) AMD Ryzen 9 7900X 32GB (2x16GB) G.Skill F5-5200J4040A16GX2-RS5K WD SN570 2TB MSI NVIDIA GeForce RTX 3080 Ti Win 11 Pro |
