The second I start cinebench or any other all core workload my 5950x immediatly drops all cores to 0.8 ghz. Temps are 50 degrees. Please help

#

the second I stop the all core workload speeds immediatley jump back up to regular speeds

my god, that's not thermal throttling anymore..

wise knoll
#

it is not

#

doesnt even have time to heat up, just as soon as you start all core everything drops

#

Have you installed any overclocking apps

wise knoll
#

only ryzen master

marble viper
#

Or overclocked or underclocked using the bios?

wise knoll
#

but was doing it before I had master installed also

#

i have PBO on with limits disabled

#

havent changed any settings manually

marble viper
#

Ok

wise knoll
#

I thought it was something to do with windows power settings, i changed settings from balanced to ultimate, and then it fixed it, and then I rebooted it and started having the issue again

#

i can take a video of the issue for you

#

Try turning off PBO

wise knoll
#

ill try that rn

marble viper
#

Then go to Control Panel > Power Options > Choose or customize a power plan > Ultimate > Change plan settings > Change advance power settings > Processor Power management

#

Check the percentages

#

Was wrong, pbo was on auto, not what I said it was on before

wise knoll
marble viper
#

Ok

#

Try to disable PBO

wise knoll
#

Going into bios rn

marble viper
#

The problems from these sudden clock drops are usually caused by PBO settings

wise knoll
#

Like hitting power limits?

marble viper
#

I found this reddit post about a 5950x with the same problems as yours

wise knoll
#

PBO off fixed it

#

Before I was getting 4.8-4.9 all core

marble viper
#

The issue with the 5950x in the said reddit post is also the PBO if im not wrong

wise knoll
#

Interesting

#

I’ll have to do more research abt it

marble viper
#

Yeah

#

So this is solved?

wise knoll
#

Yes thanks
