RX 580 auto voltage range is weird

Hello,

Is it normal that AMD drivers raise my RX 580's voltage to 1193mV up to max 1200mV?

Because if I hit the "default" button in Sapphire Trixx, max voltage won't go over 1150mV. And if I try to edit the voltages in AMD Wattman, the 1150mV are preset there too in last three states, even before installing Trixx. So why is AMD Wattman raising the voltage to 1193mV and then to 1200mV on default/auto settings? Is this a feature or a bug? Happens on 18.9.3. driver and also the newest driver 19.3.2. and some older ones.

Only way to get the 1150mV is to tell Trixx to use default settings, or switch voltages to manual in Wattman.

1.2V is the AMD spec for RX 580, maybe 1.15V is what the BIOS programs the GPU to run instead?

Yes, the BIOS's max is 1.15V for the last 3 states.

So are you telling me the voltages are normal and it is not a bug but a feature? Shouldn't the AMD driver respect the BIOS specs?

the boot voltage doesnt care, it's used regardless of BIOS settings.

Ah ok... Thank you very much. I was worried something was wrong with my card, because I always saw the max 1.15V voltage for 3 months since I got the card, probably because I used Trixx before and hit the default button. Yesterday I was playing around with Wattman then installed a new driver and noticed my voltages run at 1.2V which scared me. Purging everything, even with DDU did not help.

I think the AMD driver should load BIOS defaults tho. It just uses more power and produce more heat for no reason.

How is it with NVIDIA? The driver ignores BIOS settings as well?

Nvidia cards don't ram the GPU to 3D clocks like AMD cards do in the first place so the voltage at boot is lower than voltage at full load :P but by default Nvidia cards follow the BIOS settings. Pascal for example is voltage locked to 1.1V but some cheaper cards only reach 1.05V no matter your custom settings.

I dont know Trixx, but Afterburner lets you apply profiles at boot. Just save the default settings as a profile.

I'm not sure what do you mean by "at boot", but the voltages I reported were while gaming. IDLE voltage stay at 0.750V both with AMD defaults and BIOS defaults. RX 580 is locked to 1.2V max, so I was surprised I get this voltage... especially when BIOS defaults are 1150mV max.

I know about the Afterburner, thank you. I used it for monitoring, but AMD has their own monitoring overlay.
I just switched the voltage settings to manual in Wattman.

boot voltage is the voltage the GPU core gets when it starts up as your turn on the machine. On AMD it's almost like how a car engine starts up. Maybe the settings just stick as it doesnt read the BIOS again after boot.
