Sapphire RX570 Bios Flash

[exosios]

Hey there,

i'm trying now since 2 days to flash the bios of my Sapphire Nitro+ RX570 8GB but had no success till now.
I tried different methods which i found. It has Samsung memory, so it should be easy to flash.
Sadly it didn't work with any of the settings which i used.
I also tried to flash it, directly uninstall amd driver, reboot and then install other (blockchain driver). But that didn't work either.
Also with with keeping the same driver it didn't work.
I put the setting which are in 1:1750 to the others which are above.
Also other settings which i found on the internet i tried, but didn't work.

So am i missing out a step or am i just too dumb to flash that card?

Thanks in advance

what bios are you trying to flash ? You modded your own bios ? or downloaded from the internet?
What tools you using to flash your bios ? or mod your bios ?

Find this for patch driver after flash your bis - atikmdag-patcher-1.4.6
PolarisBiosEditor.exe this for auto editing timing on bios
atiflash_277  - flashing tool

thx 4 the help, it was the patching afterwards. It seems i downloaded an old version of the software.
I've modded my own bios or tried to auto mod it.

The bios flashing worked now, but the hashrate didn't increase rather decreased.

Any clue what that could be?

DO you have the right version of the AMD driver installed? I installed from the AMD site somewhere in Oktober the last version of the blockchain driver, and after starting up I had a very bad hashrate (20 MH, while I should have 24 for a standard card). There was a bug in the AMD driver, so they have now released a new version of the Driver. Try to uninstall the AMD driver with DDU and reinstall the latest blockchain AMD driver.
