I tried the shorting mod but the error is still there ( Windows has stopped this device because it has reported problems. (Code 43) ), I also reinstalled all the driver. I guess the 1x is really limited in this MB
I have 5 gpu with the exact same motherboard. Everything works well with the risers but I'm having issues with the 1x slot. For some reason it does detected the gpu but can't install a proper driver or does install but can't be recognize with the miner.
