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

this is my Sapphire RX 570 8GB modded bios gives

1106/2100
812mV
30.48 MH/s
75 W

That's great, i didn't get that kind of hash in my 570 8gb I only got 28.9MH, if you have a copy of your mode kindly share it to me, oh by the way if you have also an asus strix rx 570 4gb it would be grat if you share it here. Thanks

Don't complicate it. Just use Polaris Bios Editor. Here is step-by-step instruction which will make it easy: https://www.kryptex.org/en/articles/radeon-rx-bios-en

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/2
K4G80325FC 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

If you have samsung memory you can just use ubermix 3.1 timings

or follow guide

https://bitcointalksearch.org/topic/guidetutorialxmrethhow-to-mod-bios-rx470570480580-vega-mining-1954245

Applied ubermix straps 3.1 in +1750 to stock bios
Miner starts with 28mh then goes to 0, driver seems to fail

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.

I disagree on "way better" part, as simply copying 1500 strap will bring him to 25-26 MH/s range in most cases, while
custom strap mod is needed for 30+

Reliable, yes, nothing bad can happen by simply copy 1500 strap to above ones

Also, didn't previously notice, but links above are for original, non modded BIOS-es, so absolutely no help in this case

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

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 have a card Asus Strix Rx 570 8G with Samsung memory.
Looking for minning mod bios I have found these two:

https://www.techpowerup.com/vgabios/215807/asus-rx5708gb-8192-190722 (apparently for micron)
https://www.techpowerup.com/vgabios/213125/sapphire-rx5708gb-8192-190411 (samsung but for Sapphire cards)

Theres nothing out there for a card with my exact settings, whats the relevant information for looking for them the card model or their memory type? If I try the ones Ive found, I am risking the cards?

Just copy straps from samsung based Sapphire card, and paste them into your card BIOS
