Hi,

Somehow no matter what I do, either benchmarking or gaming, I can’t get my Core 9 185H to boost to 5.1Ghz for even temporarily. Already switched to Win 11 Performance mode and only change I did in the BIOS is setting 65W cTDP.

Latest drivers has been installed from both Windows and Intel. May I know if there are other settings I can try? Windows efficiency mode can be toggled ON and OFF but it didn’t make a difference. Any advice is appreciated.

Thanks in advance.

    Turbo Boost is automatic. It doesn’t start at 5.1GHz right after the computer is turned on. Instead, the computer will automatically adjust the frequency according to its own needs.
    How Turbo Boost Works
    Turbo Boost technology enables the processor to automatically increase its operating frequency beyond the base frequency when higher performance is required. It’s an intelligent and dynamic adjustment mechanism.
    When the computer boots up, the processor usually runs at the base frequency. Because during the startup stage and when handling some simple system initialization tasks, a high frequency isn’t necessary to complete these operations. For example, when loading the basic drivers and services of the operating system, a lower frequency is sufficient to handle these tasks with lighter loads while also saving energy.
    Basis for Automatic Adjustment
    The computer will automatically adjust the frequency according to the workload. When running software that demands high processor performance, such as large-scale games, professional video editing software, 3D modeling software, etc., the processor will detect these high-load tasks. To process data more quickly, improve the system’s response speed and the running efficiency of the software, the processor will automatically increase the frequency. To reach 5.1 GHz (assuming this is the Turbo Boost frequency of the processor) to meet the requirements of the task.
    For example, during video rendering, the processor needs to quickly process a large amount of image data and perform complex calculations. Turbo Boost technology allows the processor to increase its frequency within a short period, speeding up the rendering process and thus shortening the overall rendering time.

      It’s OK, I’ve found out the reason.

      Besides Windows performance profile, need to enable C-states in my BIOS for me to see the 5.1Ghz boost.

        I have the same issue. 4.8ghz Max single core boost. Not 5.1ghz . Enabling C States fixes it but now when idle or big change in load it hangs. I have the impression the bios defaults are set so more needs to be changed than just c states. Anyone have a good stable suggestion that still allows proper boost? Cinebench R23 Single and multi show much better scores with c states enabled. Should not hang just turning that on.

          Nang Adjust power management settings in BIOS, like switching to balanced mode.
          Check and optimize CPU voltage settings carefully.
          Make sure cooling system is working well, clean dust if needed.
          Test memory stability with diagnostic tools.
          Please press delete key as soon as you turn on the PC, so that you can go to BIOS. Please send us a picture of the Main page.
          We will check if you need to update the BIOS.

            Nang might be other settings that are making it hang.

            Is your Windows updated and power plans checked to enabled 100% CPU? Then go to BIOS and restore factory defaults. Just enable the C-states and see if it hangs. If it doesn’t then progressively change the settings to your liking and rebooting each time to check for stability.

            At least that’s what I did.

              Thanks much appreciated will try both of these and let you know.
