[BIOS Mod] RX480 -> RX580 Conversions + How-to RX470/RX480 -> RX570/RX580 - Page 28

I start the program and see:

On log window there is output:

My origin BIOS:
48M8BFA1.zip 109k .zip file

My card is XFX RX 480 Tuned by XFX - Custom Backplate XXX OC - reference cooler and custom backplate.
On origin BIOS I have throttling - when i set 50% Power Limit core clock still lower than 1288 MHz.
When I modify BIOS like describe in post 3 so change that card is recognise as RX580 and increase Voltage and TDP, TDC, Power Limit with Polaris Bios Editor there is no throttling but got a black screen and must reset PC from button, got blue screen or driver crash. On card I have a water cooler on core and radiators on VRM - temp not higher than 60C.
I need help to prepare a BIOS without throttling and any other issue which I describe. Maybe you can look at attached BIOS file and prepare somethin for me please?

the "XFX RX 480 Tuned by XFX - Custom Backplate XXX OC" is nothing but a reference design. I have the BE Edition of that card, i have to know.
XFX also says this card has a different number: RX-480M8BFA6
http://www.xfxforce.com/en-us/products/amd-radeon-rx-400-series/rx480xxx-rx-480m8bfa6

i just call it the russian xfx then.. and since it has uses an IR3567B controller, it doesn't matter anyway, i have the original BIOS and can provide a BIOS that fits your card.
it has one more register than the reference card, 0x26, which is supposed to be the voltage offset for both loops.. i don't know why that should be a reason if u have trouble with the ref BIOS..hmm.. register 62 we don't know but it is totally different.. and the PowerPlay table is at 0x1000 higher offset than on any other 580 and 480 BIOS.. weird thing you have there. Where did u buy this card?

anyway, give this one a try:
xfx.russian.480-580.1.0010.rom.zip 108k .zip file

Thanks for BIOS file. I will try it and give you feedback.
I am from Poland and buy that card in local shop. From begin I know that this card is different than standard reference card. For example the low memory state is 601 MHz but on standard reference is 300. I regret that not buy any other model because with that I have a lot od trouble.

I have seen a lot of people mentioning this zero fan disable, but I don't really understand why people want to do it?

I just set a custom fan curve in MSI Afterburner, and have no issues with the fan or temperatures, is there something I'm missing as to why people want to remove zero fan?

Yeah, I also wonder.
Running MSI AB with custom profile but I still stop fans below 50C

@hellm I played a all day FIFA 18 and everything looks fine. But after 8h I got error:

The same problem I got on any other rx580 BIOS. I play on celan system( I do Windows reinstall after flash).

There is something complete different about your card, i don't know how to solve this problem. If you have problem after switching the original BIOS to a 580, we just can't do anything about that.

Wait, there is a thing, SoftPowerPlay:

i am sorry i can't help u with a BIOS-mod for this card. Maybe i will have an idea, but i doubt it.
post #278 of 372
Ok. I understand. The problem is that on original BIOS card not work good. Probably I musy l sell it and buy sonething more userfrendly. Thanks for help.

I can't understand why his card cannot work with a ref bios using same voltage controller? I wonder what is so different about his card.
I have seen this error in some games in past, not sure if it is really related to gpu bios or not.

8 hours is a long time for an error to occur.
Maybe change what you do, get directX from another game or source and re-install and don't install / play apps or games you used to.
Instead try something new for a while and see.

I used to see that error somewhere, sometime in past and it wasn't related to gpu itself.
I remember something but it is really not clear, if you have an iGPU, can you try disabling it?

also that error might have happened if your GPU isn't stable. We already have seen a case with @MiladEd,
according to him, his card doesn't work with 1200mv but as far as I remember, you have tried the method in post-2 and didn't work again.

Yes. I have trouble with modified BIOS but also in original. Now when I play CS GO the gamę close. Without any error. And the reason for sure is GPU because on previous I do not have that situation.
