Topic: Rx480 Nitro+ OC(11260-01-20G) Samsung Ram Stock BIOS (Read 128 times)
Those cards can have 4-5 different bios version if i remember right from my earlier builds
Also this build is with 11260-01-20G , i had to mod 4-5 different bios file for those cards, i ordered the cards from different places.
My project is completed today all , 16 cards installed with custom ROM's, Take me forever to mod all those BIOSes . YEP , i have 12 XFX rx 480 , same model number , but i had to create 7 different rom for those cards to work stable. I was not able to use 1 modded bios for all 12 cards . Higher ASIC quality cards have more overclocking potential for sure 
, and much easier to mod those rom files for those cards:) Also i got 4 Nitro 8GB OC , those card have 3 different BIOSes . ( 13-2E3470U.X4L / 13-2E3470U.X51 / 113-2E3472U.053 ) Rom files are not interchangeable . You can flash them to another nitro , but then your hashrate will drop to lower 20's or under or just going up and down.

Hi all,
First of all sorry for my English..
I lost my stock BIOS roms. I searched every single page on the internet but i did not find any original rom for my Rx480.
Thus i want to ask you.. Do you have original(stock) default and silent rom for Sapphire Rx480 Nitro+OC (11260-01-20G) with Samsung ram?
