CPU frequency at 100% usage 10%

Solved

Hello,

I'm reaching out to you because I've hit a dead end. For the past few days, I've noticed that my CPU is overheating and I decided to investigate why. I observed that the CPU frequency is always at its maximum even after disabling the Intel boost in the BIOS. In the screenshot, the Intel boost has just been disabled. I also tried changing the power options, whether in normal mode or others, but it remains the same. If you have a solution for me to return to a normal frequency, I would appreciate it. Thank you in advance.

Problem solved, it was my Razer software that was consuming a lot of CPU frequency, everything returned to normal when it wasn't running and no more overheating as a result.

Could you tell me how you found out because I have exactly the same problem

Hello,

Normally, we install with the default BIOS and default Windows, then we don't touch anything.

If the CPU is overheating, usually the issue is the cooling, I should actually redirect your topic to that section.

What is your cooler?

I haven't touched anything, apart from what I mentioned earlier regarding the issue I noticed. In my opinion, the problem doesn't come from the cooling; it's not what would cause my frequency to stay constantly at 100%. Otherwise, it's a Corsair H100i v2.

It's normal for your CPU to be at its maximum clock frequency; it's the 100% usage for no reason that would be abnormal.

For me, a Corsair H100i v2 is a complicated gadget, a Achilles' heel.

Why make it simple when you can make it complicated.

I'm redirecting your topic.

Hello,

What do you blame your processor for? Its operating frequency is 3.7 GHz, and that's always the frequency it works at, whether it's doing little or a lot... it's like "chérie FM," it's 102.2 MHz... for the lyrics or the music...

It's used at 11%... so that's almost nothing... the fact that it heats up means nothing... measure its temperature and give some figures... you can also check the specifications of your i7-8700K processor to see what the manufacturer considers normal operation; and from what value they think it's dangerous...

You created this deadlock for yourself!!

So whether the processor is working or not, its frequency will always be used at 100%?

The frequency is not "Used", it is clocked (in English) (At a clock frequency) and I would be more concerned if it was stuck at a low level.

No worries as long as you don't manually exceed the clock x by yourself (Overclock)

The frequency x is determined by stability and temperature, operation and cooling.

Poorly implemented water cooling is much worse than standard Air Cooling.

Maybe we should investigate why it is not working well, is it poorly installed?

Is there air in the pump?

Do you hear the pump pumping?

How hot does it get under load?

I just ran the tests max 65-70°, and I just looked on my wife's PC and that of a friend, the frequency adjusts according to what they're doing, it doesn't stay at its max like mine, so there is something going on somewhere.

No overheating.

When I check the frequency, it's with CPU-Z.

I don't remember why my base frequency is 3.8GHz with my I3 10320, but it is always at 4.5GHz.

But I've seen it at 3.8, but it wasn't with the same RAM; the BIOS probably chooses the best performance with the given RAM.

Otherwise, sorry, I don't have a more concrete answer about the minimum frequency, except that as long as the processor is working at all, it can't stay at its minimum frequency; that would be counterproductive.

Is your CPU sometimes below 1 or 2% utilization?

No, my CPU always stays between 10-20% usage on the desktop when I'm doing nothing, but the frequency remains at 100% while the same test on my friend's PC and my wife's goes well below their maximum frequency and when the CPU is working their frequency adapts whereas mine stays at full speed.

Hello,

"I just looked at my wife's laptop and a friend's laptop."

If they are laptops, the CPU's operation can be different; there may be 2 operating frequencies to preserve the battery.

Check the BIOS version with CPU-Z in the Mainboard tab

See if you can update it.

I think it's this one, isn't it?

https://www.gigabyte.com/Motherboard/Z370-AORUS-Ultra-Gaming-rev-10/support#support-dl-bios

You have BIOS F6

The latest is BIOS F16b

Sometimes it can fix issues, but note that there are always risks when flashing a BIOS.

Especially if you're low on power, never do it during a storm, but at this time of year, it's less risky.

But I'm not responsible.

You download, extract the .BIN file and put it on a very reliable USB drive formatted in FAT32

To access your BIOS, press the Delete key

Then there is an option to flash the BIOS

Hello

There is indeed a button on the motherboard that overclocks the CPU or some software installed somewhere that makes adjustments in addition to those in Windows, but that doesn't seem to be the case with what we see. In any case, you can set it to base frequency if you want; you just proved it. If there is software, it's the one that sets the high frequencies, but you have control; you just need to find what setting you changed.

But 3.7, as Jeannets said, is indeed the normal frequency for your CPU; it's nobody's fault if your wife's PC or your friend's PC has CPUs with a lower base frequency.

It will only start regulating the frequency if it's working significantly more than 10% and if you set the adjustments for it. It will vary between 3.7 and ? It can easily exceed 4.0 GHz on this CPU; it's not at 100% frequency but at the bottom of its capabilities. You need to watch the temperatures to see if it heats up abnormally or not; for now, your PC has nothing worrying or abnormal.

To avoid noise, whether water cooling or not, I don't set my cooling and temperatures below 40°. Everything works well in the PC at these temperatures, just the mechanical hard drive that I place near a cold air intake. If your water cooling allows you to set lower, no problem, it's never an obligation, just a comfort or pleasure to see everything working without the temperature rising.

My CPU alone can stay at 71° 24/7; it's fine at that temperature if it's consistent. It is more sensitive to temperature fluctuations than to the value itself; I set the limit at 71°.

But some CPUs and software allow you to set the limit >85°. The motherboard doesn't like that as much.

Between 40 and 71°, that's my preference; I can adjust to my liking, run load tests or not, and let the frequencies fluctuate as they will without taking risks.

I exceed 10 years of use on a CPU just to see that it still works; I've never seen a CPU fail, always outpaced by the demands of software before, obsolete.
