I7 10th gen question- Nitro 5

Hi, I have a Nitro 5 with the new I7 10750h processor and after installing Throttlestop noticed that on first run in the FIVR settings the CPU was showing as being over volted by plus 49 on both settings. I immediately set them back to 0 but I thought it a bit odd as well as the fact that apparently these are voltage locked. These things also run very hot even with Acers latest cooling system unfortunately.

    So, what is the question?

    ThrottleStop will show FIVR Control - Locked if the BIOS has locked CPU voltage control. After you apply a voltage check the monitoring table. If the change does not show up in the monitoring table, CPU voltage control is not working. If the BIOS overvolts the CPU +49 mV, this will show up in the monitoring table. You will not be able to change it if Acer has locked the voltage control register after they did this.

    yea sadly thats what happening here..
    when i change it and hit apply nothing happens.

    No idea why any company thinks Intel CPUs need more voltage. They always need less voltage. A -50 mV undervolt would have been a great BIOS option. Maybe someone does not understand the difference between undervolt and overvolt.

    yea its really weird thats why we undervolt in the first place,
    but im pretty sure acer knows something we dont..
    I mean i get it undervolting is bad, google plundervolt if you dont know what im talking about.
    but why the +50..

    Undervolting is not bad. The Plundervolt problem was caused by malicious software that was allowed to rapidly vary the CPU voltage. A simple fix for this is to allow users to adjust the CPU voltage but only when they are in the BIOS. After that, the BIOS could set the lock bit so CPU voltage adjustment would no longer be possible after booting up into Windows. Plundervolt problem solved. Either that or give users a BIOS option so they can disable the SGX instructions that hardly anyone uses.

    If you think Acer knows something, I think you are giving them too much credit. There is no reason to overvolt an Intel CPU. Intel sets the voltage table based on how much voltage the CPU needs to be stable. Once they find this point, Intel adds on extra voltage to ensure long term stability. Absolutely pointless for Acer to add extra voltage to the CPU on top of the extra voltage that Intel has already added. This just confirms that someone has no idea what they are doing.

    ok good then must be a bug or an error and will be fixed in a future bios update or something??

    Well I'd like to think I'm reasonably competent on laptops and according to to Throttlestop this CPU was definitely over volted by +49, it isn't now as I've reduced it back! That was my basic question.... Why?

    were you able to reduce it back?? how?

    Via Throttlestop the only thing I can't adjust is the core speeds as they seem to be locked.

    you sure its saving/applying the settings? when I ever seem to do and hit apply it never does anything..

    Seems to be as temps have dropped.

    you can check using an app like HWMonitor
