I also have this switch on my sapphire RX580 nitro+ special ed. but it changes between silent and overclocking mode. nevertheless, no risk no fun and between 23 and 31 mh/s is quite a difference particularly if you have 10 cards like me in one rig. you will find a tested BIOS here https://anorak.tech/
Moreover don't forget that undervolt and overclock memory is almost exclusively possible only with modded bios.
Topic: Low hashrate on rx 570 eth (Read 164 times)
I experienced the exact same thing with my new XFX RX 570 (XXX edition). After actually looking up the card's SKU number on the web I found out it had a switch near the 8 pin power header to select between gaming (default) and mining BIOS profiles. I shut down the computer, flipped the switch to mining mode, and the result was an increase from 21.8 MH/s to 24.9 MH/s. Power draw also dropped quite a bit, too. Previously I was overclocking using MSI Afterburner to 1950 on memory (which got me to right around 23 MH/s) and even with the power limit reduced by 15% I was pulling around 350W from the wall; now it's down to 295-300W.
If your card doesn't have the dual BIOS feature then my understanding is that you'll have to modify the timings in the BIOS using, e.g., PolarisBIOSEditor. I d/l'ed the program, but I wasn't looking forward to modding the BIOS as there is always the risk you brick the card, and the warranty is null-and-void at that point.
