[SOLVED] My cores are always sleeping

[ezUnix]

My cores are always sleeping no matter what i do. I have a Ryzen 7 3700x. My cores are sleeping even when i'm playing triple AAA games and when i stress test the CPU. I have done anything i can think of. Reinstalling drivers, Resetting windows, Tweaking settings etc.

My specs:

GPU: 3070
CPU: Ryzen 7 3700x
PSU: Corsair 750W
RAM: 3200 MHz Corsair vengance
Motherboard: MSI MPG B550 Gaming WIFI
Storage:
120GB M.2 SDD
3TB HDD
450 GB SATA SSD



I also get low performance in games. And i think because the cores are sleeping the CPU is bottlenecking my GPU

You reset Windows, but was this a new OS install for this motherboard?

Nope

Nope

Most likely problem then. You have a windows configuration that doesn't match your hardware.
You can boot a portable linux OS and verify your hardware is working properly.
But you will probably have to do a clean OS install to get rid of all the "ghosts" in this box.

The sleeping cores could also be your power plan.
Check your settings.
For best performance use High Performance.
This will keep all cores active and lower their time to boost to max.
Balanced will keep all cores active but unused cores will drop to their lowest speed. 400-600mhz.
Power saving will sleep all cores possible and will not allow max boost clocks when needed. Also the time it takes to wake a core and boost to max is a lot longer. As it seems to do it in incremental steps.
A fresh clean install of windows is always a good idea when you have major hardware changes.
