Hi guys, I am just, spent 9hours of installing 10x vegas 64 sapphire limited edition. I am was able to install only 9gpus, because of the asrock mobo 110 pro btc. 9 gpus just boot fine, but when 10gpus was installed the mobo just stop working, no booting no sign of anything. I am check everything, even the swapping of risers, gpus, slots was without succes... But anyway 9gpus are in w10 and they are mining. 1350W on wall, but only 1150h for card. Even I did not saw the compute option in wattman! How it is possible? What about igpu as primary display?
Personally, I have stopped trying for any Vega over 8. I find it is semi flaky and increasing it to 9 or even 10 is really more for bragging rights. I have now gone to 7 / 8 card configuration.
