Arc B580 vram frequency stuck at maximum (2375mhz)

[nicethings]

My new Maxsun Arc B580 has it's VRAM frequency locked at 2375mhz and will not change. It therefore draws 35-40W at idle.

I have Re-bar and ASPM enabled and the PCIe root power set to L1, as well as the PCIe Link state power management set as "maximum power savings" in the control panel. I'm using the latest drivers from Intel. 

Current setup

MSI MP273U (4k@60hz) using HDMI 1.4

14600K

The display is set to SDR 8bit RGB (the problem persists even when switching to YCbCr 4:2:2). 

I've also tried lowering the resolution to 1920x1080 but there is no difference.

I've tried using different cables too. (DP 1.4, HDMI 2.1) with no results.  

There are no background tasks running. 

What could be causing this issue? How can I fix it? 

Thanks in advance.

Okay, so I found out that this is normal for the Arc B580. However, I'm still stuck with 35-40W at idle. Why is this happening? What can I do to lower it?

I figured it out. I'll just leave this here in case anyone bumps into the same problem as myself. So, in my mobo (MSI Pro B760m-A Wifi) I needed to enable one more option, ErP. With ErP enabled, I won't be able to wake my PC from sleep with my USB devices (mouse, keyboard) anymore, but I'll be saving 20W! 

I've also read that for other Mobos, you should also enable CEC and Energy Star.
