Dear Hilbert,
Can you please share the bios file? I got the Nitro+ 4GB 470 and would like to test If I can flash it later ;-).
Thanks in Advance!

You wanna brick your card?
They are Polaris based but the fabrication process is slightly different.
Just overclock your card and live with it, a BIOS flash will probably kill your card.

So was 7970 to 280x yet they would flash.

+ we got 2 bios's,
I did same with 7790->260X
R7 360->260X to run then on Crossfire ;-).
Undying
I would probably try it just like i did with Tahiti. 😀
Silva
I wish you guys good luck then.
Just remember: if you brick it, it's your own fault!

Sure,
Let me know the results as I like to learn myself if that works. And indeed, he has a BIOS switch and can easily fall back to a BIOS restore:

I doubt any increase in core performance would be had but they may get more refined memory timings.
Silva
With a way to restore even I am curious to see if it would make any difference.

Well if it works, then I will give the red devil 470 --> 570 flash a go as well.

Thank you for Upgrading My RX470 Nitro+ 4GB -> RX570 Nitro+ 4GB! 🙂
I had to use atiflash -p 0 Bios.rom -f to force the flash ;-).

What is the difference in performance?
Benchmark that bitch!
BigMaMaInHouse
I don't know, I do no have old benches.
I run this new bench, It's onlly showes on hulf of my screen(seems no support 4 2X DP 5K monitor).
I think my useless i3 6100 is to blame for the lower score.

Very interesting to observe,
The CPU can make that score a bit different yes, especially compared with a Core i3. Try Time Spy and check the GPU score, it should be a notch closer.
But you are going to need to monitor your GPU temps. I see that you are hitting a max 82 degrees C, makes sense as GPUs require more volts. I'd advise you to increase fan RPM notch to compensate or create a fan delta with MSI AfterBurner.

I haven't tried the Superposition Benchmark on my 1st PC yet. From all the reviews, regarding RX580 it is still a close competitor to the GTX 1060 6GB. I hope Vega will at lease same level as the GTX 1080.
BigMaMaInHouse
you are right, on FAN AUTO temps got high as 85 and the core frequency started jumping +-100 Mhz, forcing high FAN speed got it fixed.
If you compare the RX 470 Nitro with this RX 570 you will see that now RX 570 can hit higher Frequencies from same Voltage table.
Edit: here the Time Spy score:

The Average
ASUS 470 ROG STRIX bios
Is that bios applicable to all 470 cards? Specifically the asus rog strix oc 470 4GB?

No you cannot go cross-brand with these BIOS files. That is ill-advised.

As I expected: you're slightly ahead of original 470 but still far away from the actual 570. You just overclocked the card and that means more volts, power consumption, more heat and shorter lifespan.
The benchmark is very GPU bound and your GPU is at 100% utilization, I doubt the CPU has any influence.
If you want to leave the card like that my advice is as HH said: make a custom fan profile with Afterburner. Also, I would set target max temp to 75ºC just to be on the safe side.

check my Time spy score- it's same as RX 570, same FPS.
I am very curious if partners actually used real RX 5X0 chips and not old stock RX 4X0 chips until enough refined Polaris chips available from Fabs, because the performance/watt looks exactly like old Polaris.
