Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

Cpu frequency jumps all over the place when idle


Frequency changes quicker than thousandth of a sec constantly. I will try attach the small vid i have taken.

I have dual boot , win10 and linux mint.When in win10 it does the same , constantly all over the place from 800mhrz to 5000 and all frequencies in between. 5gig is my overcock.

In linux it goes from 800 to max 3600. Processor is i5 8600k , z370 asus igaming mb... 5 gig at 1.64 vcore. took the oc vcore off manual and to adaptive in bios to lower the idle frequency.

All C states enabled in bios but this driving me nuts.

Could this have to do with spyware physically installed on pc, long story.

thanks in advance


here is a we tranfer link.. not sure how long it remains up.. https://we.tl/t-1peIXuNawA

Update..set bios to default , still does same in windows and linux

I think hardware been tampered with at this point, does anyone have other thoughts on this situation..thanks

When you say "set bios to default", was that through a reset? Otherwise worth a try...

And check thermal paste.

There is no such thing as idle in modern OSs. Something always goes on, something always needs a bit of CPU time. Perfectly normal, don't mess with it.

When the processor is being used, open top or htop and see what process is using the cpu.

Or
Code:
watch "ps aux | sort -nrk 3,3 | head -n 5"

Along with your other thread about being 'hacked' in the past, this seems like *VERY* familiar ground. Why does it matter if things change 'quicker than thousandth of a sec'?? Different services always run, process, and complete.

And we've seen many, MANY threads here about being 'hacked' in the past few years...why do you think this? Any data? Since it's a 'long story', can we assume that you've been 'targeted' somehow?? Hard to imagine why these 'hackers' (who have physical control of your system, somehow, at the BIOS level), allow you to post things to try to remove them.

OP - you can look at /proc/interrupts to see the counts of interrupts the CPU is receiving.

A hacker who compromised my system is more likely to reply as you have, than physically stop me posting to a forum lol..but thanks anyway.

dugan, I upset some very bad people who are well networked, I cant say much more. I know they have entered the house whilst we were away. I know many things but yet to prove any of it sadly.

I could be well wrong re the bios virus they installed, but being a windows person switching to linux only recently i have always over clocked and used cpu-z to monitor cpu processes.

There are three pc`s in the house, mine is the only dual boot, another is linux and the other is windows. Last night i checked the other 2 pc`s to see if the cpu behaved the same. All three are the same, the cpu is changing erratically. I have never seen this behavior before which makes me think all three have had virus`s installed while we were away. I know for a fact they track our mobile phones.

So, of the three pc`s in the house, 2 cpu`s are 8 series intel and the other a 10 year old 2600K, all behave the same way , so it is unlikely it is a new bios feature that does this or the architecture of new cpu`s only.

Im not sure how to proceed.. Thanks everyone.

You can boot a live CD that has not been altered in any way.

Three pc`s in the house, 2 with linux an 8 series intel and a 2600K from years ago, the third pc is a windows10 pc. As i said to dugan, all three cpu`s behave the same. Coincidence that is a little concerning wouldn't you think.
