Hello everybody. I have a strange issue, may be someone can help me.
I had a two stable linux rigs with asus motherboard and four r480 gpus in each rig.
But i have a 2 r480 gpus spare.
I replace one asus motherboard with MSI z170 gaming carbon with 7 pci-x slots. With 4 gpus everything is going well (each gpu get 280-290ss) but after i added a one more gpu to the rig my hashrate is very slow. At the begining 3 gpus runs well at 280ss and 1 has a only 60 and one 150.
After a half and hour only one gpu runs full speed, other 4 has only 60-70 ss. Very strange behaviour.
Tutorial on this forum about runing 7 gpus on MSI z170 gaming carbon didn`t helped me.
