Thanks a lot guys, I have bookmarked every link and also will try the one click mod bios. I guess blockchain driver is the way to go with modded bios but this I can easily find out myself.
Edit: Locked the thread because this video is all I needed, now I can do it real easy the BIOS mod. https://www.youtube.com/watch?v=JKM60VVIfRg
Topic: Sapphire Pulse RX 570 4GB Bios mod where ? (Read 345 times)
This is a good basic tutorial on how to mod AMD cards: https://bitcointalksearch.org/topic/guidetutorialxmrethhow-to-mod-bios-rx470570480580-vega-mining-1954245
This is also a great source: http://www.overclock.net/t/1604567/polaris-bios-editing-rx5xx-rx4xx, not necessary to mod your card but you can learn better about how the process works and how to custom-mod memory timings instead of butchering lower frequency memory straps into higher ones.
There's also a document that explains the most important GDDR5 timings but I can't seem to find it at the moment.
Definitely read through this entire thread if you want to get more into it: https://bitcointalksearch.org/topic/custom-ram-timings-for-gpus-with-gddr5-download-links-updated-1758267

First you must load bios from your cards with atiflash, type atiflash -s 0 old.rom
Best to do with bios is to download latest polaris bios editor 1.6.4 and to load in him your bios from card.
And in polaris bios editor use one clikd mod and save new moded bios
Then you go to atiflash and save bios to all cards.
Almost all card with one click mod can do 30+ on eth, and lots of them about 31.5m

i have some rx 570 4gb hynix and they are doing dual mining 29 mh/s and 800 decred at 105 watts from wall
you just have to copy straps from 2:1500 all the way to last highest strap
and then flash the modified bios in you gpus one at a time

Thank you I am watching videos on Youtube and there are some but I prefer better to read a step by step guide from google. However couldn't find any step by step guide for this thing. If anyone is good enough to share some links for me to read I would be grateful. I already got all parts and will start assembling hopefully on weekend. Until then I hope to have found a perfect solution for bios mod.

I tested a few Sapphire Pulse RX 570 4GB before buying them and they were with Hynix Memory would not be able to overclock through Afterburner as this kind of memory doesn't support it. I was very happy with stock results in dual mining ETH/LBRY with 24/70 Mhs respectively. The problem was power draw, was 150 watt when dual mining, when mining only monero was 95 watt.
I am looking for a good Bios mod and a step by step instruction as is the first time I will do a bios mod to my cards. I can buy one but first I am asking here if any help will be provided hopefully.
