I use this Claymore 10 settings "-cclock 1340 -mclock 1750" and undervolt -96, for about 30.8MH/s ~ 31.0MH/s Eth and Dcr 616.462 Mh/s dual mining.....with no memory errors and securely 60°C - 65°C 24/7.

Use it freely, but I'd appreciate some ETH donation.
If for some reason you can't flash this BIOS, just extract 1750 strap and replace your original from 1750 to 2000 strap, then increase MEM max frequency to 1750 Default and Clock 1340 and flash it.
Those are some nice results, 31Mh/s + 616 Mh/s at just 1750 memory clocks?
I guess u used custom straps for that?
29.8 Mh/s + 65 Mh/s LBRY @1200/2080 is as far as i came on my RX 570 4GB Nitro+
