Hello and welcome,Thank you Mini_me for your work.
Anyway on this site: https://bitby.ru/bios-rx5600xt-mod-en.php I found unlocked bios + timings. Interesting thing is that my original bios has 512kb. From site bitby.ru I download bios for my card and has 1024 kb.
Can you help me with flashing this bios? I dont understand which tool use for flash rom on my card.
I attach this modified bios.
