You have to extract YOUR bios and modify YOUR bios, and them flash on yout card, it's way better and more reliable than download bios on internet and flash, you can use these bios in last case Follow this tutorial: https://www.reddit.com/r/EtherMining/comments/6z2it1/how_to_bios_mod_rx570_4gb_and_overclock_it_for/You have to basically extract your original bios, modify the timings (copy 1500 timing straps up to the 2000), then flash the modded bios Remember to save at least one original bios of your card

I'm sorry if you understand wrong, maybe I did't explain well I just said that he could do the bios mod with the original bios of card, copying the straps, not download some bios and put on card, working with the original bios is better The OP said "I have a card Asus Strix Rx 570 8G with Samsung memory"And he put links of Asus and Sapphire bios, it's a recipe to brick the card if he flashes wrong bios

Thanks for the responses. Yes sorry I didn't explained it properly, I know that I only have to copy the straps on my BIOS. I was not sure if copying straps from another video card BIOS can risk mine, and if I do it, whats more important, same video card model or same memory brand. I used to have many different types of rx470 three years ago, and by following this guide https://www.reddit.com/r/EtherMining/comments/6z2it1/how_to_bios_mod_rx570_4gb_and_overclock_it_for/ I didn't get the expected results. Then I found modded bios for the same cards, copied the straps and obtained 29mh/s. Now I cannot find a proper BIOS example to copy, so thats why I created the thread, to know if I will do something wrong by copying the values for the examples I shown you.

do you have a sample of a command line for this vios mode? I am using Phonix miner v 5.0e I only got 29MH for my Sapphire Nitro Plus RX 570 8gb, I know there is a way to increase my hash power, and also my miner always crash in every hour of running sometime my rig lagged. I hope you will share the good command line. Thanks

I followed the instruccions, N-th timing strap for an N-1 frequenc gives me 22mh (25mh is at stock). Memshifting from 1500 to down gives me a slight improvement agains stock timmings, 26mh I ended up here: https://github.com/IndeedMiners/PolarisBiosEditor/issues/2K4G80325FC is my memory code and none of ubermix timmings worked for me I applied the straps provided by BoriZka67 and resulting in 31.2mh with 2100/1150 and 97w
