Sometimes a new claymore version will do worse with specific GPUs. My guess is thats what is happening. Try changing:
CLAYMORE_VERSION="9_8"
to
CLAYMORE_VERSION="9_7"
Thanks it helps. But only if i am mining ETH solo. When i switch to dual ETH_SC claymore 9_7 the hashrate ETH goes down, but SC goes up. I noticed if i change argument -dcri nothing happens, doesnt matter do i do -dcri 0, -dcri 40 or -dcri 100. Is it possible something wrong with 2unix or 3main setings becase -dcri argument doesn't Influence
Try manually switching dual mining off on one of the cards after it has started by pressing a number 0-9 (ie.e GPU0, GPU1, GPU2). Pressing a number once to turn the mining for that GPU off, press it again to go into ETH only, check numbers, and you can resume dual mining by pressing the same number once more (you will see text of what state you are in while your doing this in terminal). If it is caused by the dual mining, try to manually lower the DCRI in the terminal by using the - key. ( + key = increased hash rate of second coin, - key = lower hashrate of second coin)
