Hello and thank you for everything. Currently, I have a 5600XT in which I have flashed the modified bios by Red BIOS Editor. However, the BIOS did not work, the system hangs during POST. This is no problem, I am used to flashing BIOS with SPI Programmer CH341a, I am free to test anything.

I think maybe this did not work due to the fact that my card is dual BIOS, and when I read the BIOS from the memory chip, it comes out with 1024kb, rather than the 512kb saved from GPU-Z. When I try to open this extracted BIOS with RBE, it modifies fine, but does not save by stating "An unknown error occurred when accessing (filename path). This is not a permission issue, I am running admin. It works fine to save the file when I use the GPUz extracted rom. However, even with the 512KB file, it does not work to post the card.

I have tried several things, the last one was to make only a very small change on the GFX Maximum Clock to 1900MHz. It still does not work. I originally made a BIOS with a lot more changes and limits, such as 2100, 1000 memory, more power, voltage, etc, etc. but decided to make a small alteration to see if it would work-- unfortunately it doesn't.

I have also tried to open in HxD the original long file 1024kb and noticed it makes no difference, because after 000FFFF0 it is only 0's anyway. Also, in HxD, I have tried to open the original stock BIOS and overwrite the part, leaving the correct file size, but this also did not work to POST. Stock BIOS still works fine when re-flashed, card is perfect.

So, I am leaving a link to my files, to see if we can figure out why the modified BIOS is not working on my 5600XT.
Here is the URL: http://xonedigital.com/BIOS_etc.zip
on this ZIP file, there are the following:
1 - 5600xt1_gpuz.rom (Original BIOS from the card extracted with GPU-Z)
2 - 5600xt-stock_extract.rom (This is the BIOS file extracted from the Chip with SPI Programmer, it loads on RBE, but fails to save)
3 - mpt-1900_only.mpt (This is an example of a small change I tried to see if it would work, only changing maximum clock to 1900mhz)
4 - 1900-ONLY-BIOS1.rom (This is the final outcome of RED BIOS EDITOR using the GPU-Z BIOS with the MorePowerTool settings of 1900mhz)

I hope this helps, thank you so much for all your work again and let me know if anything else is needed. I am really looking forward to free up the power of this 5600XT :)

Thanks again!
 
Hello Mini_ME.

I am surprised to see you are helping a lot of people here, very kind of you!
I have a lot of rx580's and i modded those bioses myself. That was easy t do with Polaris One Click.
Now i replaced the 580's for Asus Dual Radeon RX 5600 XT EVO's and ASUS TUF Gaming X3 Radeon RX 5600 XT Evo's.
I try to mod those bioses for mining but i can't manage to get it done. There are cards with Micron and Samsung memory. Now i am wondering if you would be so kind to help, so i can learn from it.
If i give you one bios for a DUAL, one for the TUF Gaming Micron and one for the TUF Gaming Samsung, can i use these for all of them?
Hoping you want to help and I am so bold as to already include bioses.

Mini_me has kindly generated me an unlocked bias, thank you!

However I am still a little concerned to flash as the BIOS I loaded from the card via HiveOS is 1MB, and the modified version is 512kB,

If it is the wrong bios and the card gets stuck can it be easily re-flashed with HIVEOS?

Thanks in advance
