Free transfer to the “new” series. Several users of IT forums have successfully uploaded the RX 580 and RX 570 bios to the RX 480 and RX 470 boards. Such an option could be expected, because in the end the new Radeons are refreshing Polarises, where no substantial changes were made. Nevertheless, the confirmation that we just received was important.
As the first possibility of replacing the bios in the older cards with the core Ellesmere informed the forum Guru3D user about the nickname BigMaMaInHouse. He successfully uploaded the Sapphire Radeon RX 570 Nitro + 4GB software to the Radeon RX 470 Nitro +. Newer models offer higher clocks, so forumowicz has obtained in this way dozens of additional megahertz.
A few hours later similarly TonybonJoby from the TechPowerUp forum, who has blown his XFX Radeon RX 480 with Sapphire Radeon RX 580 Nitro + card bios. This example is a bit more interesting, because the 1411 MHz Boost (obtained by the Sapphire bios) obtained in this way was not possible to achieve on the standard bios of its construction. The user mentions that the maximum frequency for full stability was 1350 MHz. It looks like the Sapphire model simply has a higher voltage setting for the core and probably a revised power limit.
The card itself was tested in Witcher 3 and FurMark – both tests went through without much problem. At the same time, however, every clock increase in Afterburner caused a driver error. Just flashing ATIFlash, bios from the new Radeon series and typing atiflash -p command 0 Bios.rom -f (where Bios.rom is the name of our target bios). However, it is worth noting that not always the same upload can finish for us and our card happily, so the whole operation you carry out on your own responsibility.
