Don't bother modding the gpu because it's 4gb version and they are short of enough memory for Ethereum DAG, meaning if you mod the. Bios you aren't getting anything pass the 25mh, pretty lucky there you know, many RX570 580 with 4gb memories are getting 21mhs
What other coins benefits from BIOs modding? Please enlighten me because everyone are modding their BIOS to get better hashrate on Ethereum Ethash Algorithm only, I've never heard about people modding bios because of Monero or other coins
But if he mods it when he cant mine eth anymore the coins he can mine will benefit from the bios mod.
