    Hi,

    Trying to use theottlestop and whilst I think it's taking an effect the issue is that when I try to stress the CPU it's only at 70 degrees and going down to 3.5GHz? Any idea why this is happening?

    Open up Limit Reasons. Find out why your CPU is throttling. It is likely one of the turbo power limits, PL1 or PL2 that you will see in red in Limit Reasons. That is your reason for throttling. Many HP laptop computers set these limits so they cannot be increased or changed by using any software.

    Thanks, exactly the reason, I turned on performance and it didn't seem to throttle, I ran a TS Bench and the temperatures were at 90 degrees at 4GHz , this is after repaste, guess this chip just runs hot?

    How do I ensure the undervolt is working and that I'm not effected by the "plundervolt"

    I'm running at -0.140mv on core and cache and -0.50 on iGPU although not sure if that makes a difference, it's a bit tempremental however, seems to be hitting those limits again and throttling, however only to 3.8GHz this time, and temps under 80 degrees. Can't work out why it's throttling when before it wasn't.

    **Edit** - Turbo boost long power max was at 50, and short power power max at 90, I changed long power max to 90 and it seems to have got me through one pass of Cinebench.

    Did you try doing that yet? If your CPU is not running at its full rated speed, there has to be a reason why. Limit Reasons should be able to report that reason.

    Open up the FIVR window. In the top right hand corner is a monitoring table. This table clearly shows what offset voltages your CPU is currently using. This table is continuously updated every second. In the Offset column does it show +0.0000 or does it show the offset voltages that you have set in ThrottleStop? If you are using a bios with Plundervolt protection, this column will show +0.0000 from top to bottom which would confirm that under volting is not working. If you see your offset voltages in this column, your under volt must be working.

    The iGPU under volt will not work by itself. You have to under volt both the iGPU and iGPU Unslice equally.

    I am having exact same problem on my omen 17 i7 9750h, Despite having temperature headroom and sufficient power available, it just takes 60w(it does draw around 70w for a min in beginning of any stress test though). I didnt have this problem until recent bios update.
    Any way to remove this cap?

    Try using the ThrottleStop FIVR Disable and Lock Turbo Power Limits feature. If this does not solve your problem, it probably cannot be solved.

    Post some screenshots while stress testing. What does Limit Reasons show? Are you using ThrottleStop to under volt? Does the monitoring table show that this is working? HP seems to be the first company blocking voltage control.

    @unclewebb . Yes Finally the ThrottleStop FIVR Disable and Lock Turbo Power Limits feature has helped me. It has removed the cap.
    As you can see here at the beginning the cpu is drawing 70 watts. Screenshot (12).png

    In the limit reason it will show thermal Red. How ever this changes after 1 minutes to this. Screenshot (14).png

    Even though having heatroom to push to more watts it wont go past 60w. The result.
    Screenshot (18).png
    A meesly 2630 score, which is very low compared to what i had achieved post bio update.

    But after the ThrottleStop FIVR Disable and Lock Turbo Power Limits feature turned on,
    Screenshot (20).png



    The only thing holding the cpu back is thermals....Which is good since the stock paste job is literally the laziest thing i have seen.(Am planning on applying mx4 2020 edition after a week or so). So i may pust to 3k score.

    UPDATE- Regarding th UV, yes i do use TS for undervolt. My settings

    So, How would you rate my settings? Do i need to change anything?

    That's a great undervolt, but your CPU is overheating. Not even using Prime95?

    It's up to you, but I'd never let it go over 90 degrees under Prime95 (30 or so minutes). A few minutes shaved off a rendering job ain't worth a fried system board.

    You'll need to do some serious cooling mods for 60W+, HP's heatsinks are barely enough for the stock 45W :/

    Just because it's going over 90 doesn't mean a fried motherboard, the system is capable of operating over 90. With a -0.140 undervolt in Cinebench I'm getting around 90 degrees, Prime 95 would almost certainly throttle the system, but it's fine, that's why the system has the throttle function built into the CPUs.
