Need the bios for HIS Rx 480 8GB ICEQ X2 (Hynix Only)

[testerr86]

Hello everyone

I have an HIS Rx 480 4gb IceQ X2 graphics card but since I have seen many people are able to unlock the remaining 4GB VRAM by modding/flashing their bios.
I also thought why not try it on my own, but I have not been able to find bios for my card, I just hope someone has it, if you do then please send me the link, so I can try my luck too.
