Intel core i7 12700H used to reach 4.7 GHz, but is now limited to 4.1 GHz

[Jérémy]

Hi,

I have an HP omen 16 that is equipped with an Intel core i7 12700H.

The max turbo frequency of the 6 performance cores is supposed to be 4.7 GHz, and indeed, until some time ago, I was reaching 4.7 GHz as long as only one core was under heavy workload and the computer was plugged in to AC power.

However, since some time ago (I think since the last BIOS update), I can't go over 4.1 GHz in the same conditions.

Following the recommendations of Intel, I downloaded Intel Extreme Tuning Utility in order to check what was going on.

Here is a screenshot :

As you can see, the multiplier of the performance cores is 41x, which, multiplied by the reference clock of 100 MHz, gives indeed 4.1 GHz, which explains why I am now stuck at 4.1 GHz

Since all the options are greyed out, I can't change these values back to 47x

As I use this computer to run numerical simulations in astrophysics, having a frequency of 4.1 GHz instead of 4.7 GHz means my simulations are 13% slower ...

All the options are greyed out. How do I change these values back to 47x again ?

These multipliers used to be at 47x, but for some reasons (once again, I suspect the recent BIOS update) are now to 41x

Please, I really need to recover the 4.7 GHz that I used to have

Best regards,

Hi @Jérémy

Thank you for posting on the Intel® communities. I'm sorry for the inconvenience this might have caused you. Please help me with the following information in order to assist you: 

•  Did you notice the change after that update? 
•  Were you overclocking the processor before? (The reason I ask is that this processor can turbo up to 4.7 GHz with no changes)
•  How are you checking the frequency of the processor? 
•  To get more information from your system, please install the Intel:registered: System Support Utility (Intel:registered: SSU): https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows- Open the application and select "Everything" click on "Scan" to see the system and device information. By default, Intel:registered: SSU will take you to the "Summary View". Click on the menu where it says "Summary" to change to "Detailed View". Click on "Next", save the report and attach it to your response.

Dear Carlos,

Sorry for the delay in my response.

• Did you notice the change after that update?

To be honest I'm not sure. I wasn't constantly reviewing the frequency of my processor, so I can't say with absolute certainty that the problem was caused by the BIOS update. It could be completely unrelated.

• Were you overclocking the processor before?

No. Nor did I ever try to do so.

• How are you checking the frequency of the processor?

So I have been checking the frequency of the processor in two ways. I am dual booting fedora linux and Windows 11 on this computer, and I run my numerical simulations on fedora.

On fedora, I can easily check the current frequency of the processor cores with the command line cat /proc/cpuinfo | grep MHz. Until two or three weeks ago, I was indeed having one of the 14 cores running at 4700 MHz when doing a numerical simulations. Now, it is only 4100 MHz. Since I have been noticing the problem, I am also checking what is happening on Windows, in case the problem was with fedora.

Which is why I downloaded Intel Extreme Tuning Utility. This tool showed me that performance active core tuning is set on 41x, even for only one active core (see previous post), which explains why I can't go over 4.1 GHz, and which showed me that the problem was not with Fedora. And so, the second way I check the frequency is with Intel Extreme Tuning Utility. Even when I run a benchmark, it does not go over 4.1 GHz.

To summarize, I check the frequency of the processor cores in two independant ways, both showing a maximum of 4.1 GHz, even for one active core.

And here is the report you requested.

Hi @Jérémy,

 Thank you for the information. Just to clarify, the tab you are looking at in the Intel® Extreme Tuning Utility is to overclock the processor, so I would like to try the following for me:

• Run the CPU stress test with the Intel® Extreme Tuning Utility and provide a screenshot of the process halfway through and send it to me.

Hi @Carlos_L_Intel ,

Thank you for your answer,

• Run the CPU stress test with the Intel® Extreme Tuning Utility and provide a screenshot of the process halfway through and send it to me.  

I ran the test. Here is the screenshot.

The frequency stayed around 3.5 GHz for the whole test, but all 14 cores were active. It might be interested to run a stress test with only one core to see the 4.1 Ghz, but I don't know how to do so with Intel® Extreme Tuning Utility

Hi @thinsys,

 Thank you for the information. One other thing I would like to know to continue with my research, when you run numerical simulations what is the program you use? Would you be able to check its frequency? 

 It might be the CPU can be thermal throttling as well, is the computer in a well ventilated area? Have you checked for any dust accumulation?

Hi @Jérémy,

   Recently I bought Laptop HP Victus 16-d1135nw and have the same problem. My BIOS is F.12 version.

   Have you managed to solve your problem ?

All the best,

Piotr.

This processor can't have any overclocking settings, so the question is are you messing with the settings in the BIOS? Try all settings to default. Or set Intel turbo boost manually, enter 99 in core ratio such as 1 core, 2 core, all core then Bios will automatically set the highest possible value. Enable all Intel cpu technologies like speed shift, eist, therm opti, c states, velocity boost...

Hi @Piotr2 

Nop, I never found were the problem was, and my i7 12700H stayed stuck at 4.1 GHz for quite some time.

However, about ~3 weeks ago, my BIOS got updated to version F.15 (from F.13), and that solved the problem. I am now back at the announced 4.7 GHz when running my numerical simulations.

It is still unclear if the problem is with HP or Intel. But they definitely messed up something with the BIOS.

Anyway for my future laptop, I think I'll go for the AMD ryzen 7945hx, as it has a bigger cache than the current one, and will be faster than the current one for numerical simulations. For gaming however, the size of the cache matters a bit less.

Hi Jeremy,

   Thank you for reply.

    Good news - your problem is solved, 

    Bad news - it doesn't apply to my Laptop HP Victus 16-d1. Still the last Bios version is only F12.

All the best,

Piotr.

Hey jeremy
I have had the same problem with my laptop, the hp omen 17 and i still cannot find the issue
I have already installed the latest bios version and am still capped at 3.2 gigahertz. Is there any way to fix it?

[Cohan]

Are the updates for these laptops the same? If so where did you download them from?

[Cohanayaya]

Hey Jeremy,

Can you please reply I still haven't solved my problem with my omen 17 i7 12700h and I am losing on a lot of performance I am also on the latest BIOS version f16 and I can't seem to find what the problem is

[Piotr2]

Hi,

    For HP Victus 16-d1 new bios F.14, but problem still the same : CPU speed no more than 4.1 GHz !

All the best,

Piotr.
