I have the Vega "Blockchain" drivers installed (fresh install). If I try to use any of the settings bellow as per the tutorial, I will hash for no more than 3 or 4 minutes, my screen goes all pixelated, and Windows 10 crashes forcing me to reboot.
If I leave Cast running with "default" Vega settings, I am hashing at 1600H/s and its stable, but I obviously want to increase it if possible.
Settings I have tried without success:
1900 Hash/s with 150 watts power consumption
Core Frequency: -10%
Memory Clock: 945 MHz
Power Limit: -22%
2000 Hash/s with 200 watts power consumption
Core Frequency: -10%
Memory Clock: 965 MHz
Power Limit: 0
2050 Hash/s with 225 watts power consumption
Core Frequency: -10%
Memory Clock: 990 MHz
Power Limit: +12%
Anyone have any ideas on how to properly tweak the Vega settings as I dont really have any experience on overclocking or undervolting GPU's.

Try adding on the command of cast-xmr.exe: -I 2 --fastjobswitch
What does the command do for the card exactly?
That command should lower a little the intensity of the mining process, I still get a stable 1910H/s with that command
Ok, so I have now installed the Vega 64 BIOS and I'm running:
Core Frequency: -10%
Memory Clock: 1105 MHz
Power Limit: +20%
And only getting an average of 1982 H/s @ 280W power usage. Seems like low hash rate for the settings with high power usage. GPU is sitting around 68C with 3300 RPM on the fan.
Is it nessesary to do the power-play hack to the registry in order to touch the 2050 H/s realm?
