All those users who chose to install an AMD RX 460 graphics card in their computer are in luck, not only because of the new drivers, but because from the overclocking.guide environment and more specifically its author, der8auer, has managed to unlock the RX 460 , offering a performance improvement in a free way for users.
The AMD RX 460 is the only graphics card that is based on the Polaris 11 GPU architecture. This graphics card has 896 Stream Processors that allow a theoretical performance close to 2TFLOPS. This graphics card is clocked at 1090MHz and clocked at 1200MHz in Boost mode, with a total of 2GB of GDDR5 VRAM memory. This graphics card also has a variant with 4GB GDDR5.
The process only requires a small firmware update that offers us a performance improvement of 12.5%. This graphics card, through this update, becomes a great option regarding quality / price. Thanks to the update, we will get an extra 8TMU compared to the 56TMU of the graphics card in its current configuration and it has 128 more Stream Processors.
CAUTION: Not all AMD RX460 graphics cards may be able to receive this update and be unlocked. It is also possible that something goes wrong in the BIOS during the firmware update process. If you do, it is at your own risk and expense.

Update
The list of graphics cards has been updated, with the confirmation of support in the Sapphire RX 460 2GB and the XFX RX 460 Passive Edition 4GB, also we have the HIS RX 460 iCooler OC 2GB, which has not been tested. We will keep updating.
Unlocking process
Unlocking it is a fairly simple task. The reason why this possibility exists or why it does not arrive unlocked as standard is unknown. There are two explanations, which are either not powerful enough as AMD expected or AMD would not have enough chips to make all the RX 460s that would be needed.
Here we bring you only the BIOS update for the Sapphire Nitro 4G graphics card and for the ASUS STRIX O4G. In the media where they have published it, they say that they are working on more tests with more graphics cards and if it works, they will publish the modified BIOS versions. All six tested graphics cards support unlocking.
The first thing to do before starting the unlocking process, we must make a backup copy of the original BIOS, in case something goes wrong. This process can be done using the latest version of the GPU-Z. Once we have the backup made, we will execute the file to unlock the BIOS. This takes a few seconds.
Performance improvement
They have carried out some tests using 3DMark Fire Strike and The Witcher 3. We see in the results that the ASUS STRIX offers a performance increase of around 10% in Witcher 3, while the Nitro improves considerably in the 3DMark Fire Strike, which increases over The 9%.
Conclusion
This improvement sounds interesting, especially since at the level of quality / price the RX 460 is far ahead of the NVIDIA GTX 1050. We do not know if the data is before the driver update or later. If it were before the AMD driver update, the improvement could be brutal, hovering around 20% approximately, if later, it would stay the same, with approximately 9% in general. We will be attentive to bring news about it.
If you can do that with the 460 then you can also convert the 470 into 480 through the bios?
We do not know if that will be possible at the moment. We will be very aware of any news in this regard, but at the moment this is only in two graphics of the RX 460 family. If it is discovered that this happens in other graphics cards, we will inform you as soon as we know it.
the relive driver does not work but the crimson
A question, I have this 460GB Asus Strix 4 card and a while ago I did this procedure and what happened to me is that after restarting with the other modified BIOS, it does not recognize the drivers and practically cannot be used! So I returned to my original BIOS and that's it!; But now I have 4 Asus Strix rx480 8GB cards, I know that the rx 480 can have the BIOS timing modified to make them have a mining power of around 30 Mhs !!, do you know how to modify the BIOS of the Asus Strix rx480 8GB ???, I also tried a few days ago a procedure modifying the BIOS timing of 1 of my 4 cards and when I restarted what happened is that the Claymore does not recognize it and I can not put it to mine so I had to return to the original BIOS again and now everything is fine!; But there must be some way to modify the timing correctly to increase the mining power of my cards, right? If you know something and can tell me, I would appreciate it!
How did you go back to the previous bios?
is that before touching the original bios and flashing any card!, you must always backup the original bios!, and if something goes wrong, you have to put back the bios that was backed up!. I use ATIWinflash v2.74, watch videos on Youtube how to use it, although it is very easy!; but if something goes wrong the card is ruined!., if you need the original bios there is a page that has many bios of many cards!, but then it is complicated to know if it is exactly the bios that is for your card because if you put another bios by mistake!; your card may be ruined too!.
on this page are the bios and the atiwinflash program. https://www.techpowerup.com/
Hello, I need to know how to use the back up. Could you help me with that?
Good day I just did the procedure this but after doing it the drivers do not detect me, what do I do about it?
you need to put a patch on your pc !, so that the driver you have detects the card !!. look for the patch it's called: atikmdag-patcher-1.4.5
