RX 480 Cards Can be Flashed to RX 580

I might upgrade my 7770 to a 570  

You'd need to download more (v)RAM.

 

 

I have a 7950 and an R9 280, and software randomly see each card as either of the two names (although "correct" names are more likely than "incorrect" ones). Hardly matters...

Now, the question is which, if any, BIOS setting is different. If it's just an automated way to get what you could do by manually tweaking a 4xx, it doesn't do much, other than give you an overclock preset that may or may not work with your card anyway. However, if it overrides some hard-coded limit in the 4xx series (for example, if voltages couldn't go above X, but 5xx allow for higher voltages), then I could see how this enables more OC possibilities. And more risk simultaneously

Hmm interesting..will do that when i get home (evil laugh)

It's not unexpected as it's basically the same card, save for some optimizations in the silicon. You could do it with the previous cards as well.

Thought about trying to flash my 470, but the biggest increase I've seen is about 3fps, so I'm not fussed.

Just like 290 to 390 and even 290 to 290x. The chip is fundamentally the same and the bios advantages are minimal, the "refined" process (a.k.a. better yields for better binning) is really what counts.

 

Not that I am too exited about this products but that's simply because I am still fairly ahead the mid-range market now.

Rip AMD... looks like everyone's gonna be flashing their 480s instead of buying the RX5XX series

Except for the fact that those 580 wannabes won't be as stable at that voltage or clockspeed.

They may not have really changed much, but refining the process and core itself still helps quite a bit.

85c is a minimal difference from 67c? Whatever dumb things you envision are a personal issue. The RS has a worse heatsink than the nitro 480.

I didn't say there wasn't a difference. I think it's irrelevant to whether one should flash their card. Idk where you are getting those temps from either I've had several nitros and a couple xfx 480s in builds I've sold and they both ran in the 60s in realistic scenarios (games at max) with reasonable fan curves.

Hey, my card can do 1400 on 1.2V, but the voltage unlocked BIOS has weird issues with it. Maybe I can flash mine to an RX 580 Gaming X

I'd flash mine into ashes

You can flash and then undervolt! Wait...

I should probably try downclocking my RAM, but I don't think that's my problem. I used to be able to do 1440, now my GPU becomes unstable beyond 1370. I have a feeling it's the newer drivers causing this. What driver are you on?

I though you gain more performance overclocking the VRAM compare to CORE?

That's if you have the slower 1750 MHz card. Mine is 2000 MHz. There isn't much gains going from 2000 - 2200 so I was thinking of downclocking to 1900 or 1950. The GTX 1060 is the card that gains more from VRAM overclocking as opposed to the core.

(Oh boy, can't wait for Computex only for Volta to be released not too long after)

you can use a single bios card if you have another gpu lying around to boot from so you can rescue it should it go wrong.

 

Done it before

Well, there is probably no performance increase in doing so (that you couldn't do with a manual overclock), so no really compelling use to doing this... but I guess if you want to buy a RX 580 sticker then BAM it's a whole new card. Anybody with a dual-bios 480 here at LTT going to attempt it?

 

A little help here. I have a 4gb 480 and i want to do this as i have a dual bios. ive tried programming the 8gb 580 bios onto it as i cant find any 4gb versions. It gives me the subsytemID mismatch. Is there any way to bypass this and if i do, could i break the board itself, bot the bios? all help is welcome

There are only 8GB versions available on TechPowerUp at the minute and I don't flash my gpu much/at all so I don't know any other sites that have a collection of BIOSs sorry. Someone else might know a good site?

What's the benefit of new BIOS for the old cards? If the RX480 silicon cannot handle 1450 MHz, it still won't do 1450MHz with the new BIOS.

From my experience modding 290s/390s BIOS it won't POST. 

 

For mismatch you need to use -f when flashing.

 

Try lurk in this thread from OCN forum and hopefully you'll learn something useful regarding Polaris BIOS modding. http://www.overclock.net/t/1604567/polaris-bios-editing-rx5xx-rx4xx/0_20

As a Linux Gamer, the biggest thing of this is: I can finally have my Card running under Linux with 1400 MHz, without any hassle...overclocking is possible on Linux, but Voltage Control is a bit sketchy, so hurray for that! And 200 MHz do actually make a difference with OpenGL...

Seems my card has a dual bios, so I MIGHT try this

Personally a bit more interested in if the 570 can be successfully flashed with the 580 firmware.

What good will that do? It still has less compute units, less ALUs and less texture units. Most of the 470s/570s also do have different memory, so it probably wont run at the speeds the 580 runs it

He probably meant if you can unlock those disabled CUs by flashing 570 to 580.

Which isn't possible, since AMD Disabled those CUs Physically. Source: Various Reddit Threads, that have flashed a 470 to a 480 (which works, mind you), but did not unlock any CUs - Ergo: probably disabled by a fine tuned laser.

 

Apparently some 470s had problems, getting over 1290 MHz, which they don't when flashed to an 480 Bios. Still: No CUs and still less power than the 480. Since the 570/580's are the same Chips, i highly doubt, that there is any difference. Flashable? Probably, but only advisable if you've got a BIOS switch on that 570.
