Thanks for the advice I'll try it out. biggrin.gif

This may have been covered earlier, but does anybody know why the fans on the card spin up to 100% briefly as you boot into windows and if so how to stop it?

Thread Starter 
in the fan table (post#3) are a few values between idle PWM and zero fan enable/disable; in almost every 480 BIOS it is 64, but there are also found different values in some 580s, like 96 or 78. I think it is some spin cycle i-don't-know, you have to try and error. maybe changing the first two values, but again, i really don't know.

Just an update for anyone it may save time.

I'm on MSI Gaming X RX 580, 8GB.

Flashed v11 (latest as of writing), added ubermix 3.1, and stock clock rates, then I used the new magic GOP in hopes of getting through UEFI check.

The new GOP doesn't bypass UEFI, I have to enable CSM mode, not sure who said that it can do so, but it is not working for me.

Everything else is working fine, but I sometimes get screen flickering every hour or so, I assume it's the VRAM timings slightly unstable or just another AMD driver bug.

Edit: Do I need to copy Ubermix 3.1 to 1750 strap from 2000, or was that comment directed at another user with a different setup?

The 1.63 "magic" UEFI/GOP is thoroughly tested and in use by a lot of people now. And, of course, it is already to be found in the newest versions of all my conversions.
So, you were about to copy 1:1 over same bytes, but i guess something went wrong.

For the UberMix, it is like i said above. wink.gif

Hi,

I gave up with edit my own BIOS. I have a random blue screen or device driver crash. I flash RX480 Reference BIOS (ref480-580.1.0013.rom.zip) and those situation did not exists. Now my problem is a big throttling. When I play games or run benchmark the core clock is fluctuate over 1100-1150 mHz and the performance is not too high. Could you help me resolve this problem? I would like to have a stable core clock when card is loaded.

Thanks you in advance for any help.

@hellm

Do you plan to change default power limit on MSI card? As I reported 180 -> Thorttling.

For info about actual 580 Gaming X,
I have found a video of actual card somewhere running in OC mode 1393 mhz. (I think my card cannot redface.gif)
it uses 1175mv default and drops to 1150mv under full load.
We cannot know its tdp because MSI does OC mode Slient mod thing a little different as you might now. So there is no bios, it is just software overclocking.

This is not a problem for me because I underclock to 1150mv anyway, but it might be better for some other users who wants it to just run 1360mhz and don't touch anything.

What card are u using? And what is exactly the problem with your original rom?
As i said many times, it is not a good idea to use the BIOS of a different card. Performance loss is the least of it..

Yes, the Gigabyte support already gave me a hint, oc-mode is software based. Load line up to -25mV is customary for Polaris.
I don't know if i should raise that to 200W, maybe i leave a note somewhere about those damn spikes and where in the thread to read about it. i think that would even better.

I use XFX RX480 XXX card model 48M8BFA1. On my original BIOS modified as shown at post 3 I have random blue screen or device driver crash.

Can you pls check with vrmtool if you have the IR3567B controller? Just start the programm and see what happens.
vrmtool

still wouldn't explain why you have trouble after switching. i hope you extracted your original rom, not downloaded anything you suppose it is the right one? sorry, have to ask.

The BIOS you uploaded is not a reference nor is it a GTR. But it should have the IR3567B, i just don't know about that XFX card. The RS models don't have an IR controller, so..
