4GB cards will only hash at about 11-12 MH/s in standard Ethereum.
If your GPU0 is a 4GB card, then your hashrate on that card is false. Several miners have posted pics and videos of RX cards with crazy hashrates, but all the shares are rejected by the pool.
What are your miner settings?
See the whattomine page for the RX 570 4GB:
Win10 —> 8.00 Mh/s @ 120W
Linux —> 12.00 Mh/s @ 120W
Side note: I hope you didn’t get ripped off by your “friend”. RX 570 4GB cards are pretty much USELESS in Ethereum mining now. Your profit for the whole rig including electricity for the whole month will be less than $200 USD. You’d make more money removing all the RX 570s, selling them for $99 each and using the money to buy something else with more VRAM to put in the slots.
