[SOLVED] Ryzen 5 5600x one of the cores not acting like the rest / cpu freq #4 at 4500mhz at 50% load but the rest are under 5% load at 3600mhz

Hi, I recently upgraded my build swapped into a ryzen 5 5600x, a new mobo asus 550 prime and g skill ripjaws ram, everything is running well, idle temps are around 35c-39c, but I notice sometimes even if I'm just browsing (firefox) one of the cores will shoot up to 50% load and freq clock will be around 4500mhz while the rest are sitting at under 5% load at 3600mhz and my cpu temps get to 65c around at that moment. I do have precision boost overdrive on but I don't see why it would activate if I'm just browsing. Any thoughts? thanks.

what are you using to track temps? how long does it seem to stay high?

try using HWINO and change the polling rate so it resets more often and is more accurate - https://forums.tomshardware.com/threads/how-to-use-hwinfo-to-track-sensor-values-on-ryzen.3693704/

Ryzen works in a way that if a process needs to be done, it will wake a core, boost it to speed it needs to run process, and then rush to idle.

I only have a 3600xt but one of my cores is always going up and down all day. I just ignore it now, as most cores stay steady.

Its normal.

I ignore it by tracking Core temperatures and Average Effective clock, shows more an overall view of what all CPU is doing

Ryzen works in a way that if a process needs to be done, it will wake a core, boost it to max for as long as the process needs, and then rush to idle.

Core Temp 1.17.1 to track. I just did something I closed my apps one by one and it seems like the Battle.net client by Blizzard just having it on idle in the background gets one of the cores to go to work instant 50% load and increase in clock, that's interesting...

that seems odd as I have the battlenet client and it doesn't act like that here.
I see its update process using .2% every few seconds but not sure what cores it using each time.

Your Battle.net App uses a form of torrenting, which saves Blizzard money, but it’s also CPU intensive. You can forcibly throttle your bandwidth via the battle.net app settings on the World of Warcraft tab.

Bandwidth shows on the settings/download tab of Battlenet app
