My system's initial configuration:
Ryzen R7 1700
Gigabyte AB350 Gaming 3
2x4GB Team Elite 2400 Mhz DDR4
Powercolor Red Devil RX Vega 56 8GB
Sapphire RX 560 4GB
Powercolor RX 560 4GB
Thermaltake SmartRGB 750 watt PSU
The system is mostly used to mine cryptocurrency when I am not using it.
I recently purchased an MSI Airboost RX Vega 56, so I removed the two RX 560s and installed the MSI Airboost Vega 56
First time boot I can get into windows and windows recognize it and showing two RX vega 56 in device manager.
Then windows crashed and autorestart.
Then windows boot again, got into it, and then blank screen.
the msi vega 56 tachs light is off.
Then I removed everything and use the MSI as main GPU. It works fine.
Then I added the RX 560 again one by one. Work fine.
So it seems the motherboard has problems stabilizing two vega 56 in windows. Anyone has suggestions on why?
Thanks for your answers.
