okay, so this bios is downloaded from hive. try this one VBIOS
Looks like this is a match to your cards, cant be sure because off missing info where xxx.xxx.xxx are…
It wont do no harm if it fails.
if it works, download Polaris bios editor free version. Open the vbios file that worked before with this software and just click “one click patch” right down corner of gui and answer yes to prompts and the save rom to your files, name it so u no what is what … and upload to your hive library and try to flash again, its with faster timings so more hash and higher OC.
