Cpu multiplier keeps changing

[xDylanio]

Well I used prime95 to check my cpu, and boom it hit 100 c. I do live in texas so it's pretty hot here.

But I checked on aida64 and my cpu multiplier kept changing. I don't know if this is normal.

 

A few seconds after

Seriously, when your pc is at idle/doing nothing, the multiplier goes down, because the CPU power isn't required. As soon as your PC has to do something, it will go back up.

Intel Turbo Boost technology, that's why the multiplier is constantly changing to meet the best efficiency possible.

How can I turn it off? (If possible)

Sadly, i wish it was that easy, but it is not.

@PenPoint Not sure about "intel turbo boost tech", but I do wonder. My AMD system without turbo will have an multiplier that goes from 8x to 35x, and with turbo on, up to 45x. It's how things work.

Compair it to a car. When you are driving at 5 mph, it's not very efficient to have your engine rev up to 7k.  It only needs to rev up, when you are actually using it somehow.

In case of AMD, it's called 'Cool'n'Quiet'.

It's part of the built in power saving features. If you want to turn it off, change your Power Plan in Windows to High Performance.

Either you have an overclock set or Intel Turbo Boost is active. You can disable this through the BIOS of your motherboard. The button to get into the BIOS when your PC boots up is sometimes different from motherboard to motherboard, but I think most of them will all respond to the Delete key.

 

You should also look into a better cooler if it's that bad in my opinion. The Cryorig H7 or Coolermaster 212 Evo are good choices for budget options.

yes it's normal, your CPU is trottling to prevent you from destroying it.

100c is incredibly hot and it's not normal make sure your CPU cooler is well seated and that you used a proper amount of thermal paste.

I don't know for sure if it's just my cpu cooler.

 Ive looked online and people say its normal for haswell cpus to get this hot in prime95

100c is not normal for a 4.2ghz i7-4790k. Either the thermal paste dried up acting like a insulator or your cooler isn't fully seated on the CPU. Either way, I would remount the CPU cooler with fresh thermal paste and be sure to check all the case fans for obstructions. Then redo your prime95 testing to compare.
