Found this on the forum

My xfx rx480 rs also takes a while to spin down, whether i have min acoustic freq set to stock 1060? Or 920 in testing.

I could run a hard occt test, get fans up to 90% and then quit to desktop with idle clocks... Temps drop to 40c and still it takes a while to slow fans down, like the driver ignores the bios or watt man settings!

Reinstalled the driver, same thing. I got used to it

I'll just leave it here:

I've modded BIOS for my Gigabyte G1 Gaming RX 480 8GB with timings taken from reference RX 480 BIOS found in 1st post in this thread. Made it very unstable, so went back to Gigabyte's stock

Then took the "Uber-Mix Extreme" timing

and manage to OC memory to 2085MHz @950mV with 0 EDC errors
With core set to 1250MHz @1100mV i hit 29,5 - 31.2MH/s mining etherum using 115W (HWiNFO)

No matter what timings (stock, refference, modded, strap from 1650/1750) temperatures or core clock, I cannot go over 2085MHz. I almost immedately start counting EDC errors then and the system crash is immimnent.

Any ideas how can I cross this 2085 line?

Can anyone else with a Custom Polaris bios check the new driver released today. It seems at least to me on my system that custom bios are now totally hosed for the polaris gpus. I tried it both with the bios patched and not patched. Patched it just locks up during the windows boot up.

I want to figure out this out as I did a bit of surgery today and modified my old monitor LG 29UM58 (non freesync) with a main board from a cracked screen LG 29UM68-P (freesync) I found on Ebay for $9.99 Right now it will be a pain to put back in the old monitor main board.

Latest driver from today is 17.3.2

The new driver doesn't seem to work with the bios only patch program. But then I ran it again to patch the custom resolutions and that worked to get me back with the new driver.

So with 17.3.2 run the atikmdag-patcher.exe regular and patch all the stuff and it will work. (not the bios one only, that doesn't seem to work- until it gets updated?)

I used atikmdag-patcher-1.4.4 it think it patches everything at once not bios only.

There are 2 ways to use the ATI pixel Patcher...full patch or just bios signing. As someone here as pointed out and also in another forum...for some reason now you have to use the full patch vs just the bios singing patch for it to work on custom bios.

I am pretty sure I was just using the bios sigin method last night to patch the driver. This morning as other said I used the full patch and my custom RX 480 bios is back in action.

You just rename the ati patcher to atikmdag-patcher-bios.exe to just patch the driver for bios signing. It still shows as if everything is patched but only the bios signature is patched.

Fan speed wise, try setting the RPM limit about 500 to 750 rpm higher than it's default value possibly to test? Or match pwm sensitivity to same as rpm limit. If we could set fan speed type to "0" then it would run at what we set. With fan type "1" or higher it ignores everything and doesn't perform properly. Maybe this can be edited via hex and be static on all bios mods?
