Hello guys ! The TechPowerUp already has 2 bioses from RX590 ... https://www.techpowerup.com/vgabios/?manufacturer=XFX&model=RX+590 I have an XFX RX580 Very similar from the pictures. Do you think it's possible to flash the RX590 bios to my card ? I have dual bios just in case ... but not sure how to flash the one that will fail maybe. Thanks !
You can do it with atiwinflash. Its simple and you can always revert back if it fails. Let us know how it went.
You mean this one: https://www.techpowerup.com/download/ati-atiflash/ ? I'm 99% sure I will get a subsystem id version mismatch ... can you point me to a good working "dos" flashing tool ? atiflash or something similar ? Can I force flash from atiflash (win) ? Thanks.
OK I will only flash a Sapphire RX580 Limited Edition bios to it for higher TDP ... how can I force flash from Windows ? or which is the best "dos mode" version to use ? Thanks. I'm looking at this bios: https://www.techpowerup.com/vgabios/191263/sapphire-rx580-8192-170320-1
Yeah there is no software to change the bios subsystem id so its not worth a shot. Like others pointed out its made on different node and quite a bit higher clocks than a 580. Anyway you can flash it in windows. Just download the bios, extract atiwinflash files and put everything in the same folder. Make sure card is running on the bios you want to flash.
USE AT YOUR OWN RISK. YOu need to use command prompt within windows to flash with the required switch to bypass the subsystem id mismatch. atiflash.exe -f -p card number rom.rom
Lol, right... things I did in past tell different story. BIOS compatibility is not about nanometers, it's about modules inside and values it sets + chips on board it supports. If he edit that BIOS and reduces clock, he may be successful. Maybe change in memory table will be needed too. But one should check VRMs stuff too. There is reason why RX580 & 590 have same 67DF device ID.
Just reporting back...I promised myself I would not try this but WTH. Okay you can flash the 590 bios to 580 card however the card is not being detected in Windows. I have an XFX 580 that I flashed with the XFX 590 bios. The bios flash is successful and it is shows the card correctly in atiflash with the new bios. It is a start. Though I did edit it to reduce the core clock...and that might be my issue. /edit Okay the problem might be AMD released a different driver today just for the RX 590. With todays date. /edit 2 flashing it does not outright brick it...it is just not being detected in windows other then as a MS basic display device. /edit 3 overclock.net is already on it and looking at the issues.
Yeah I could install the driver but still a no go. There are some interesting entries in the 590 bios that are different then the 580 bios in the power sections.
I could not yet get that info to read out...since it was not properly detecting the GPU and true to form on polaris it shows the 65000 numbers instead of voltage. Some people are looking at right now. I just can't work with that due to other things I am working on. I flashed it just as proof of concept as people on overclock.net were scared they might brick their RX 580 card.
You just gonna brick the card. Different process between the two. 480 to 580 is possible but not recommened. Not every Polaris card can run those clocks.
