I made the timing changes in my Sapphire rx 570 8gb nitro+ bios. Unfortunately, I lost the file with original bios backup and now my card doesn't work. Could you please help me with original bios recovery? The memory type is Samsung. Or at least post the original timings for both memory banks. Thanks in advance!
Go to techpowerup.com > databases > vga bios collection (gpuz should show your bios vers.).
