Cachooox Posted January 16, 2020 Share Posted January 16, 2020 (edited) Hello everyone! I am trying to passthrough my GTX 1070 Gaming X without success, I can see the graphic card in windows but I can not remove the code 43. What I have tried: Install windows 10 following this: https://www.youtube.com/watch?v=miYUGWq6l24&t=1205s Passthrough gpu following this https://www.youtube.com/watch?v=1IP-h9IKof0 Modifying vm xml so that the slots for the gpu and sound card are the same following this: https://www.youtube.com/watch?v=QlTVANDndpM&t=662s (min 4:50) I can not boot in legacy mode because of my motherboard. My specs: CPU: Intel® Core™ i7-6700K CPU @ 4.00GHz RAM: 16 GiB DDR4 Corsair Vengeance LPX GPU: GTX 1070 Gaming X Motherboard: Asus Maximus Hero VIII My plan is to have a plex server and a gaming pc in the same pc, I am in trial mode and this is the only thing that is stoping me from buying the unraid key Please someone help me! Thanks in advance Edited January 16, 2020 by Cachooox Quote Link to comment
testdasi Posted January 16, 2020 Share Posted January 16, 2020 First, go to you BIOS -> Advanced -> System Agent (SA) configuration -> Graphics Configuration -> select IGFX That should make Unraid boot with the iGPU so connect your monitor to the iGPU display output (doesn't matter which port) to verify and be 100% sure that your server is booting with the iGPU and not the GTX 1070. Next, watch SpaceInvader One guide on youtube on how to dump vbios and dump your own vbios (with any additional changes to the header as required). Do NOT download vbios from Techpowerup. Now use the vbios you just dumped in your VM template and hope it works. I would recommend start from a fresh Windows install if possible. Also if you run out of Trial and still can't get it working, you can ask LT nicely and they are usually understanding enough to give you an extension. 1 Quote Link to comment
AntaresUK Posted January 16, 2020 Share Posted January 16, 2020 @testdasi just curious as to why do you suggest dumping own bios vs techpowerup one? Higher chance of success or something else? Quote Link to comment

Higher chance of success or something else? Because there are so many similar named cards with different BIOS code. Each card maker can tweak their BIOS, sometimes even changing the code on models with the same GPU as they update manufacturing. The only BIOS guaranteed to work is the one cloned from your specific hardware. 1 Quote Link to comment
Squid Posted January 16, 2020 Share Posted January 16, 2020 It is also possible that the card itself is no good. Code 43 is a catch-all for unable to start. My first 1050 I couldn't get it to not do a code 43. RMA'd it and I got the replacement working within 30 seconds. Quote Link to comment
Cachooox Posted January 16, 2020 Author Share Posted January 16, 2020 Thanks for all the responses! I will try that. I used this pc as a gaming pc with windows before trying out Unraid so I am sure that all the components work. Quote Link to comment
Cachooox Posted January 19, 2020 Author Share Posted January 19, 2020 It worked!!!!!!! thank you all so much! The key was to dump my own vbios as @testdasi said using https://www.techpowerup.com/gpuz/ and then removing the header as SpaceInvader said in his videos.
