Hello everyone, so I have some results. I was able to get stable with the following settings. I was able to maintain full sessions of gaming on Ultra / Maxed settings like BF1, Rainbow Six Siege, Insurgency, and GTA V. I still be playing around with the wattage that way its super fine tuned and not getting more or less than needed.
Clock - 1410 MHz
Voltage - 1175 mV
Memory Clock - 2000 MHz
Memory Voltage - 950 mV
Limit Power - 130%
With this particular card seems the only thing that makes it unstable is:
Clock Speed - 1420 MHz and higher
Memory Clock - Anything after 2000 MHz caused immediate particles artifacts in the Wattman software after hitting apply.
However before I was able to achieve, but wasn't stable after 5 mins of gaming
Clock Speed - 1435 MHz
Memory Clock - 2050-2100 MHz
Thank you again for your time and help, its always fun to see what the GPU is capable of although I plan on getting an Vega 64 or wait for the new 7nm Navi or Vega graphics cards.
