Currently having a strange issue. My CPU EPYC 7402 is meant to have a base clock of 2.8Ghz and boost of 3.35Ghz (appears to be an idle clock of 1.5Ghz). When I first start my server and get into the unraid GUI, before starting the array everything works as expected. However as soon as I start the array my CPU gets pegged at the idle clock of 1.5GHz even the base clock of 2.8Ghz isn't achieved. Stopping the array does not result in the CPU returning to normal function however a restart will.... at least until I start the array again.

 

I tested it using details given by JorgeB in the below post. I've included screenshots of the results of my tests.

Im assuming its a command that gets run upon start of the array that I'm not aware of. I've tried searching but the thread i've already referenced is the closest I could find to my issue.

ok i'm an idiot... I thought unraid defaulted the performance governor scaling... turns out it was set to powersaving... This solved my problem.

Default is not powersaving, you have the Tips and Tweaks plugin installed, it will apply the set CPU mode at array start:

You're right its not. It was my own doing when I had a 3900x. the powersaving mode gave me 3.8Ghz which was more than enough on that CPU. But I had done it so long ago I completely forgot about it. Thanks for getting back to me.
