Gawl86 Posted May 8, 2020 Share Posted May 8, 2020 Hi Guys, I have a problem with a GTX 780Ti Kp edition. I bought it some time ago from a guy. Mounted and the card seemed to work perfectly. However, going with the bios switch on ln2, the card doesn't start. Mounted as a secondary card and in windows it gives me error code 31. I try to flasch the bios of another identical card that I already owned and gives me the error overriding pci subsystem id mismatch. Reading between the lines I noticed that the card id is different so the person who sold it to me by mistake flashed the 780 Classy bios generating this error. Can you help me who are certainly more experienced than me? I have also tried other bios for the 780ti kp but unfortunately everyone gives me the same error. I also tried to force writing but in vain. I ask you and your knowledge for help. Thanks in advance Quote Link to comment Share on other sites More sharing options...
Splave Posted May 8, 2020 Share Posted May 8, 2020 (edited) Did you try adding --protectoff Can try different nvflash versions sometimes it's picky. https://www.techpowerup.com/download/nvidia-nvflash-with-board-id-mismatch-disabled/ Edited May 8, 2020 by Splave 1 Quote Link to comment Share on other sites More sharing options...
keeph8n Posted May 8, 2020 Share Posted May 8, 2020 Yeah Splave is right. I've ran into issues where a different version fixes it if --protectoff doesnt 1 Quote Link to comment Share on other sites More sharing options...
_mat_ Posted May 8, 2020 Share Posted May 8, 2020 Just adding some useless information: The PCI subsys ID is the card model. Classified will have another subsys ID than the KP. 1 Quote Link to comment Share on other sites More sharing options...
