3700x stuck at 3.8 and Voltage 1.1v

I just upgraded from a 1600 to 3700x, in general everything is working better but I can't figure out what settings I need to change to get my system to boost and idle correctly.

 

 

Specs:

CPU: Ryzen 7 3700x

MB: ASRock B450M Pro4

BIOS: P3.40

RAM: Corsair Vengeance Pro 3200 CL16

Windows 10, tried AMD balanced and regular balanced power configurations.

Cooler: Cooler Master 240mm AIO 

 

Using RM I can set the Gamer profile and my system will sustain around 4200-4300 @ 1.47v across all cores, full load drops down to 1.35 correctly.

The problem here is my system will also idle at 1.45-1.47, even if the cores show Sleep or sub 1Ghz load (few spikes every now and then)

If I switch the power profile to "Power savings" my system will drop down to <1.0v and whenever it detects enough load it starts to increase correctly, but this is just not ideal.

 

If I use the creator profile voltage drops to 1.1 and stays there, but this one doesn't boost past 3600.

 

If I press "Reset" on RM to go back to stock, I get a 4400 max speed but the same problem as with Gamer profile, it idles at 1.4+

 

Also, none of these settings persist boot so I have to open RM and apply every time I boot up.

 

In the BIOS I have:

OC      Auto

Frequency and VID      Auto by AMD CBS

SMT      Auto

Vcore offsets Auto

XFR Settings
PBO      Auto

 

AMD Overclock settings

PBO      Auto

 

 

I tried copying the Gamer profile to BIOS settings and it still doesn't seem to fix it

PBO Enabled

PPT 1000

TDC 114

EDC 168

I will boot and still be stuck at 3800

 

Any help is appreciated, I just don't know what else to try right now

 

 

EDIT: turns out I had a setting for "Custom Pstate0" at 3600 and 38, forcing the processor to get capped
