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 I originally made a BIOS with a lot more changes and limits, such as 2100, 1000 memory, more power, voltage, etc, etc.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!
 
Hey and welcome,

Great, I would like to prepare a gaming vbios that may run stably and smoothly at 2150 MHz,

I hope that your psu is at least 600 watt gold rated.
Thanks that would be great!
My PSU is 850W and gold rated, just 2-3 months old.
Just to make sure I understand the procedure, I'd just take the amdvbflash 2.93+ and flash the vbios you prepare or do I need to flash with another unlocked vbios first and then yours?
I'm just making sure because I'm not that experienced in flashing a vbios and haven't wrapped my head around it yet.

No worries, after I finish I will send you a guide to properly flash it.
 
Hi mister mini_me,

i hope at least you can help me. I think i bricked 5 asus dual 5600 xt after flash...

i flashed the bios like told in this video:
After restart i couldnt even post in to MB Bios. One of the Gpu was able to Post but i think thats because the flash wasnt succsessful.
So i tried what told in this video
Then i was able to boot in windows and flashed with a bootable usb flash drive like told in this video

Unfortunately i got the error 0fl01 during force flash and now my system boots up in to windows but only because in dosent recognize my gpu, either in device manager nor in gpuz.

I think i killed my gpus :((( is there anyway i can fix it ? i sadly dont have dual bios siwtch...

Hi and welcome,

Have you tried flashing the original backup vbios using amdvbflash v2.93+ with -f command in Windows safe mode yet?
 
Is there nobody who could help me???
I am losing 5 gpu :'(


Just tried to flash original bios with the ch341a program but it just doesn't recognize the gpu :'(

Please help :(((
 
What you mean with a lot of voltage? During flashing or through overclock(cause I did not used the gpu at all just flashed i directly)

I had a live sign from the gpu: I flashed a stock bios from techpowerup and fter I startet the system I booted into Motherboard bios where the gpu was recognized but as soon I want to go further into windows it shows the blinking cursor. And there I am stuck now.

But this is a least some kind of progress I guess 😅

When I flashed the wrong bios I also had a black screen. As a secondary card, I was able to restore the original bios with a flash. I need another card to boot from windows.

Hi and welcome,

Please use either amdvbflash v2.93+ or v3.04+ to flash the modified vbios.
 
HI!

Are you still doing to unlock locked BIOS rom? If you have time,
Can you unlock my locked SAPPHIRE PULSE 5600XT bios?
I can't get the full potential for gaming and mining as well.

Just wanted to add my part here, so thanks to @Mini_Me to show us the link of modded bios : https://bitby.ru/bios-rx5600xt-mod-en.php, i took the most close to my sapphire pulse, and it worked. In fact, I was stuck @121watt with redpanda bios (the one from garett) and I tried these bios and I still have 44.44mh/s but at 90watts now (I tried to go even lower, but my card doesn't like it). Anyway thanks to you and to bitby to share these amazing bios with us. And I finally get the 500k/Watt in efficiency.

Hello I have two ASUS ROG STRIX GAMING 5600XT cards (one micron and one samsung memory). On Windows I get around 40 MH/s but on HiveOS I can't get them past 37. I have attempted to load the bios into Red BIOS editor but both roms are not supported. I have tried several roms that I found online but all of them fail due to mismatched SSID's. Can anyone me figure out what is going on?
