A few months ago a version of the 4GB Radeon RX 480 became quite popular on Aliexpress and was on sale for $60. Although the vendors tried to indicate otherwise, these were graphics cards that had been used for mining, but still had a lot to offer in the world of second-hand gaming.
These cards, which can now be found at almost twice the price, still have very good performance, but many of those who bought them found a problem: the bios they came with was mining, which caused numerous crashes in Windows, and even the possibility of installing it.
Fortunately, this card comes with double bios, which means that with a button on the board you can select between two bios that they bring. In case none of the bios offers you good results, you can download the following one
This is the original, which will not give any problem, and even allows you to overclock to put the CPU clock at 1366Mhz without any problem in games.
To install it I recommend the Atiflash program, which can be downloaded from the developer’s website, TechPowerUP
