Ryzen CPU multiplier keeps resetting

[PhysicsNerd]

So I set my CPU ratio to 38 in my new msi x570 tomahawk motherboard. Everything seems fine abd it shows up in task manager's base speed. But in game, it never boosts to that speed. 

 

Then I went to ryzen master, changed the peak speed tp 3800 as well (it's originally 3100MHz at the 'current' profile). Reboot. When I open ryzen master it shows the correct new peak speed of 3800MHz. I open up a game (doesn't matter what game: league, assassin's creed, CoD). The core speed immediately drops from 3800MHz to ~3100MHz (as shown in CPU-Z). Andin microsoft flight sim the cpu never goes above 3.1 GHz (as shown in second figure). I don't know why this is happening, please help!! Thank you!

 

P.S. NOT A TEMPERATURE ISSUE, I have a noctua fan that's keeping it way below 50C and I literally just booted up the PC.

 

I have a R7 1700 with a x570 msi tomahawk btw.

X570 Tomahawk doesn't officially support the Ryzen 7 1700, and probably this is manifesting in this manner. You're lucky it boots at all.

Ohhh true didn't realise, kinda just assumed support given all the stuff about compatibilities for 5 years. Thanks!
