    Can you post a screenshot of the ThrottleStop TPL window? Is PP0 Current Limit adjustable? Some manufacturers set some very low limits that can trigger EDP throttling. ThrottleStop might not have access to these limits. I agree with @THEBOSS619 and you should start by trying to improve your laptop cooling system. It is not the main cause of this problem but hitting the PROCHOT temperature is not helping things out.

    @NeonSun - What CPU do you have? Sounds like a 1st Gen Core i that used the TDP/TDC settings. Post some screenshots. If TDP and TDC are adjustable then adjust them higher. Watch the CPU multiplier (speed) while benching to make sure that your CPU is running at its maximum speed. I recently picked up an unlocked W3680 to play with. Bumping the TDP up from 130 to 180 helped it maintain full speed when it was running Cinebench at 4133 MHz. I will do some testing and post some pictures later on. ThrottleStop and the 1st Gen Core i were good friends way back then.

    Thank you guys for the replies.

    I have a cooling pad, and changed thermal paste and dusted off the interior a few weeks a go.
    Sometimes the temps spike up, but not often. High demanding games temp is between 70-80C. Normal games 60-75C

    Quick question as I couldn't find it anywhere: Does throttlestop always work in the background or do I actually need to open it to work ?

    Thanks

    It depends on how you have ThrottleStop setup. There are a variety of ways to start ThrottleStop so it is possible to have it running on your system without there being an icon for it in the Notification Area / System tray at the bottom right of your screen. Open up the Task Manager. Click on the Details tab. If you see ThrottleStop.exe in this list then it is running. If you do not see ThrottleStop.exe in this list then it is not running on your computer. That is the easiest way to see if it is working or not.

    When you exit ThrottleStop, it generally does not set your CPU back to any sort of default settings. If it is not showing up in the Task Manger, it is still possible that it is influencing your CPU. Most under volting and over clocking settings will be persistent after you exit ThrottleStop. For default values, it is up to the user to set up a profile with default values and switch to this profile before exiting ThrottleStop so it can return the CPU to these values.

    So in the end it may always be sneaking in the background ;) Best thing to do then is to set a default profile, press save and exit!

    Thanks

    Question for the group.

    When Throttle Stop is enabled with any type of undervolt. HWInfo 64 reports CPU L2 Cache Error. When I reboot an do not use throttle stop at all. No errors. Prior to Nov. I had zero WHEA Errors and no issues with my undervolt.

    This seems software related. I've checked all my updates and drivers. Reflashed the bios. I am not sure what else to do.

    Thanks for the help.

    Greetings all & Unclewebb,

    Long-time RealTemp user here (on my trusted i7-920 desktop rig; still going strong after 9 years!) and recent ThrottleStop user on my XPS 13.
    I use ThrottleStop to enable SpeedShift on my XPS 13. Like some others here, I've noticed that sometimes after standby/suspend, it "forgets" SpeedShift and it's actually turned off. Has anyone discovered any solutions for this, other than manually going into "TPL" and flicking SpeedShift back on?

    Unclewebb, could this be something potentially automated in a future TS version?

    Reset BIOS to default using Dell diagnostics usb and try again.

    You can check mark Enable Speedshift when TS is turned ON.
    Provided you have already set EPP value in TS main window SST shifts between different P states autonomously. Disable Speedstep and C1E in TS only(Don't touch BIOS variables at all, doing so might lock out the CPU freq. to 800MHz) to get full power of HWP aka Speedshift feature.

    The main reason of BD-Prochot is the temperature or also can be the excess of voltage?

    BD Prochot is -something- signalling the Embedded Controller, or the EC itself, that you've exceeded some sort of limit somewhere. It can be temperature, current, AC, Battery, PCH, basically, anything outside of the normal "Package Power Limit", "Cpu voltage limit", "VR Current Limit", PL3/PL4, SVID, etc, and always causes an 800 mhz lock on the CPU.
    It's possible for this 800 mhz lock to be turned on by the Embedded Controller, even WITHOUT BD Prochot being flagged. This is very rare and is usually caused by exceeding some sort of AC limit.
