Question 13900k does not reach 5.5 in test

[adrifoxbg]

Hello everyone, for some time now I have been observing a slight delay when opening a file manager or various applications.
I use Linux but to test I installed Windows 11
On Cinebench R23 and OCCT at 100% CPU load, I do not reach speeds like 5.5 or 5.8
On Cinebench it reaches 5.3 at different times but it is not constant.
After this undervolt and Intel default profile, how normal is this?
Multicore result 36102 maximum 36889
How normal is all this for this processor?

Max Turbo Frequency
5.80 GHz
Intel® Thermal Velocity Boost Frequency
5.80 GHz
Intel® Turbo Boost Max Technology 3.0 Frequency ‡
5.70 GHz
Performance-core Max Turbo Frequency
5.40 GHz

Perfectly normal. The CPU is not going to show the maximum speed under a benchmark. You'll only see those speeds for brief periods on single threaded tasks.

You can certainly override such behavior through overclocking, though this rarely results in increased performance overall. The boost algorithms are pretty good at maximizing performance.

Undervolting can prevent the CPU from boosting higher, though the lower temperatures and power draw is desirable in comparison to 100 or 200 Mhz.

Thanks
A few days ago I smelled a strange smell from my computer, it disappeared after 4-5 minutes.
Most of the opinions on this case are about the power supply, but there were also those that referred to the phases of the motherboard
But it behaves well in benchmarks, the temperatures are good.
There is a slight delay when opening files, but it is not very noticeable
And my question was related to the fact that on YouTube many videos with Cinebench are also with hwmonitor and show how they reached 5.8 mhz
OCCT is also a good application, at 100% load 4.8 mhz ... It's a little scary

Maybe briefly, or those were overclocked CPUs. You can make an attempt for 5.8Ghz all core, just going to require hefty cooling and a lot of power.

I never overclock.
I've never been on an ASUS optimized profile, and MCE was turned off
I'm worried about this smell from the computer a few days ago, maybe it's a phase on the motherboard.

The only way to know for sure would be to breadboard the system, look at it with an IR camera to see if any of the phases were cold (or really hot if they shorted), or probe each VRM with a multimeter.

If you are worried, best to stick to default power, or less then default, and start keeping a regular backup of your data (if you aren't already)

Best to not leave the system on unattended either.

Everything seems fine, this was one evening for just a few minutes.
No problems with tests, temperatures
But at 100% load if it does not reach the speeds that are for this processor it is worrying.
The OCCT shows at the exact moment the processor load, power, and speed, maximum 4800 mhz is a bit worrying, or maybe it's normal after the undervolting of the Intel default profile.
When opening various applications, I observe the speed, it reaches up to 5.5 / 5.8 p-core, but during tests and full load it is not the case

Right, it will throttle back under a full load. And if you are depriving it of voltage it will clock itself down to maintain stability.

OCCT is a very harsh test. It would be more concerning if the system or application crashed. If it isn't, that is a good sign.

There are no crashes, and by the way it reaches 5.5 at the start of each pass, even p-core 4 is 5.8

Perfect. That is what it should do. Most people aren't hitting the CPU for minutes at a time with a full load, so that boost behavior is perfect for games, applications, and lighter work. When you move into more workstation like tasks is when you want to start paying attention to all core workloads.

Thank you very much for your attention.
