1. Download QMS http://vgaserver.tech/file/QMS.zip
2. Disconnect all GPUS from mobo and remove the 1070 from the rig
3. DDU.restart.DDU again if AMD or NVIDIA drivers are present clean and restart, DDU again until only INTEL drivers are present, then close DDU, shutdown
4. Connect 1 Vega, from Device Man. update driver/have disk.... to Blockchain Driver, when complete shut down.
5. Connect the remaining Vegas and power on, wait between 3-8 minutes do nothing.
6. Run QMS as Admin. free4all functions will auto disable crossfire/ulps on all cards and other functions and you now have a monitor to see the behavior of the bad card (with members version you would now start mining)
7. Do the reg changes you normally do (QMS is also a PPT editor and applies globally in seconds)
8. Use QMS set GPU P6-7, MEM P3 and Fan settings (same as NTool) global on the 4 and separate on the problem one
9. Start the miner and observe the bad gpu on the QMS monitor and adjust settings accordingly
10. If you like adventure add the NVIDIA card back on the rig after you just fixed it, sorry but you need a separate 5x1070 rig now ie 4 more

With QMS unlocked on member mode you can create the ppt of your choice in seconds and apply it to 1 or more gpus wit :(h 1 click, last settings are default for next powerup of pc miner starts in seconds
