Radeon RX 480 Cards Can Successfully be Flashed to RX 580
User TonybonJoby in our own forums has successfully flashed his XFX RX 480 graphics card with the BIOS from a Sapphire RX 580 Limited Edition (the one that runs at 1411 MHz Boost clocks, yes.) Having obtained the Sapphire's BIOS right here on TPU, he then flashed it onto his graphics card (which possesses a dual-BIOS setup; this is an important point which you should consider, as it gives you an extra safety net should anything go wrong) through ATIFlash. The newly-christened RX 580 thus smiles for the screenshot, with a stock clock of 1411 MHz, higher than most overclocks possible with the RX 480 cards, probably due to increased voltages on the BIOS level. The user then tested the card on The Witcher 3 and Furmark, with no problems having been reported. Just remember to back-up your BIOS with GPU-Z and make sure to peruse our forums for some details on this flashing process before you get the proverbial grease on your elbows.
Essentially, this may allow you to bypass some artificial overclocking limitation with your graphics card, probably by increased voltages on different power states of the card. You should do this at your own risk, and remember, the only guaranteed way of getting an RX 580 is... you guessed it, buying an RX 580. However, this might also give you an extra performance boost, and free performance is always good, right?

I NEEEEDDDDD
But now that the news is out, how long before the ability to do this is killed by the likes of AMD?
Lots of artifacts in heaven and crashes.
Possibly voltage controller issue.
Bring on vega :)
Also, 7970 became 280X and nothing more. Different cores were used in the 3xx series, and the 4xx series.
I do really want the 1070 to get rebranded as an 1170 or 1160 or even a bios editor to get released just so I can flash my 1070. I can hit 2050mhz and suspect I could hit 2200mhz on 1.2v as oppose to the 1.093v I'm stuck on.

The worst case I found of this was with a 660 ti direct cu II. They made various versions of these cards and I had the slowest with stock speeds with 980mhz boost which went to 1100 in game. To my surprise the hard boost limit was set to 1100mhz but after going through making a custom bios and tuning an overclock I could run 1280mhz without issue. Admittedly there was a bios update on the Asus site which silently patched the boost limit to 1150mhz.
You're in luck. Looks like that's the only bios currently posted, and has been a confirmed success for what you're trying to do. I flashed it as well on my strix, but because the outputs are different, I've only got use of one dvi port. Otherwise is working just fine.
