yeah i'll fix it, but i'm at work and di this by remote. my mistake for doing this by remote. bios is not modded since its not possible.
second bios is only ULPS on these cards wich reduces hashrate alot so no. It wont even start the cards thats found. so it's sutdown for now

Ok

so i only suspect the pool or a drop of hashrate on the miner. Try with Cast_xmr or xmr-stak.
Check if you have the last 18.3.4 Adrenaline drivers, compute mode enabled. and for Cast_xmr use --algo=1 --ratewatchdog --forcecompute
