    Have you noticed stuttering on games and benchmarks, lately?

    "bd prochot" is causing CPU throttling to 800mhz and 2.7ghz, which causes severe stuttering, on CPU intensive games.


    Laptops affected (that we know until now):
    - MSI GT72VR 7RE and MSI GT72VR 6RE
    - 7700 HQ + 1070 GTX, i7-6820HK + 1070 GTX

    How to know if you are affected:
    - Put Windows 10 in "best performance mode", before you run your favorite game, open Intel XTU and ThrottleStop (open "limit reasons" windows), when you finish your gaming session go check if you have any warnings.

    - If you have acess to the game Assassins Creed Origins or Hunt Showdown, this is the best way to know if you really have this issue.

    What do you if you are affected:

    - Run ThrottleStop, turn off BD Prochot and save
    - Run MSI Afterburner and block the voltage to 0.8750V and save


    Why this happens:
    - Nobody knows for sure the reason, BD PROCHOT is a signal from the motherboard, which is what causes the throttling and also the stutters in games and benchmarks, all throttlestop does is to read/detect it, It can be used to disable it but then the cpu still throttles which may indicate that the problem does not just lie with a faulty sensor on the motherboard, but elsewhere...

    The real solution:
    - Ask MSI to fix the problem, if they can´t, ask for refund or new laptop, simple.

    Question for msi owners with 1070 GTX laptop:

    Is your laptop free of stuttering while playing games?

    Share your feedback please!

    Thank you all.

    P.S

    @heliada, and @Pedro69, if you can, share your thoughts on this thread, thank you.

    Im thinking that the problem is the heat on gpu and i can solve the problem in 2 ways...but if we buy a gaming laptop is too play games without any issue. From what i see in web, MSI have the best laptops in terms of cooling and performance together....bd-prochot not is a problem only from MSI, many asus rog also live with this problem and like many MSI desktop motherboards.

    At least, i not have a defective GTX 1070 since my pc is from April 2017 :)

    Sure,

    But this is not normal at all, i can´t play cpu intensive games on my GT72VR 7RE, i get severe stuttering.

    For example, the game Hunt Showdown its crazy, i keep getting constant heavy stuttering.

    The temperatures are very good, no OC / Undervolt, everything at stock, lastest drivers and Windows updates.

    So this should not happen at all, this laptop was made to overclock, so it must have "room" for all of this.

    Look at this, crazy:

    Sadly, the 7700HQ was not made to overclock at all. I am not sure what limits you are encountering that forces such core clocks. If BD Prochot is causing it, have you tried using throttlestop to disable it? Sure the CPU is locked and won't overclock, but maybe something like BD prochot can be disabled.

    As far as I understand, BD prochot is a signal that can be used by the system to cause the CPU to throttle when something like the GPU is too hot, NOT the CPU. Clearly your CPU is not at high temps, but what about the rest of the system?

    @ryzeki

    We know about bd-prochot but as in my case and the @streetunder im thinking if the problem not is the vrms of GPU.

    I have not tried to disable it using throttlestop, im afraid it might harm the laptop.

    @heliada, tried to disable it using TS and it did not work, but it worked for @Pedro69

    Other solution is to lock the voltage on msi afterburner.

    As you can see in the screenshots i´ve shared:

    Motherboard 28 C
    SSD + HDD 25 C
    GPU MAX temp 73 C
    CPU MAX temp 78 C (usually max temps are less then 70 degrees, but cpu intensive games can reach 78 C)

    Great temperatures... its really strange why bd prochot is turning on.

    I don't see any VR Thermal alert sensors shoot up. Try use ThrottleStop as intended. No harm in this. And remove any varnings on Limits Reason tool after you have activated it.

    Use throttlestop. There is no harm to the laptop. If something breaks, RMA it. It should work as intended. Don't treat laptops jokebooks like valuable gemstones. They are tools to be used and enjoyed.
