Even with version 1.20 (BETA) the iGPU is on after reboot :-(

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
Good luck |

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. System: AMD Ryzen 9 7950X GPU: RTX 4090 RAM: 4x 32GB Kingston FURY Beast DDR5-5200 DIMM CL36 |
