Heya.   Been using your OS on a 6 GPU rig now for a while and it works great.   I tried to move an older 4 GPU rig over from Win 7 to SMoS, but GPU4 always goes to 0MH within a couple of minutes starting out.    Not sure if it is the motherboard or what, but I don't have any issues with it under windows at all.

My primary rig is was all at 1150/1940 for a while, and I've been slowly increasing memory clocks while testing stability with no problems.   But I'm using a PRO BTC board there.   I really liked your OS, so I tried to switch over my older rig also but had problems.

On my older Rig, I am using a Gigabyte GA-Z68X-UD3H-B3 board, with 4 powered risers and 4 RX470s.    In windows, I run 2 cards at 1100/1920 and 2 at 1100/1950, both with -20mV under Trixx.    In SMoS, it won't set it to 1100 for the core properly, and I tried it on powerstages 5 and 6 but card 4 kept having problems.   I tried it at 1150 too, but no matter what I did, GPU4 kept going to 0MH no matter what I did with it.

All cards in both systems are ASUS STRIX RX 470 4GB cards.
