Hello, I have rig with 2x rx 480 1x 470 1x 570, I flashed anoraks moded bios to all cards, first I tried 1 card only in the system, it gave me 29+mhs, overclocked... I plugged in 4 cards and the hashrate for the 2x 480 started at 29 with miner restart it dropped to 25 and now I can get only 25max, I tried flashing it again and changing few settings with overclocking but it's the same, I don't think it's problem with psu because I have 2x 550W. I don' know whats the problem... (when I tried again only 1 card, eth solo hashrate was 31.5mhs which is a bit over i think (samsung memory) then again ony 25 with multiple cards....)  (the hashrate for monero is 740hs for each card) any help appreciated
