Acer Nitro 5 AN515-42 | CPU throttle 2.0Ghz when reaching 75 Celsius | AMD Ryzen 5 2500U

Hello,

Im using Acer Nitro 5 AN515-42 v1.17 BIOS update, with Ryzen 5 2500u RX 560X 4GB, 12 GB DDR4, SSD+HDD, Windows 10 PRO.
I have proper up to date AMD Chipset drivers and Adrenaline 2020 GPU driver.

Im getting issues with my CPU. Whenever CPU reaches 75 Celsius it will downclock to 2.00Ghz (base clock) even tho it can easly handle 95+ Celsius.
Boost clock (3+GHz) gets back as soon as it drops down a bit (usually in few seconds)

This bothers me because I get stuttering ingame because of this throttling for no reason. 75 Celsius is a joke for this CPU.

I've tried to repaste both GPU and CPU. I've used RyzenADJ and Ryzen Controller (Unofficial Ryzen Master overclock tool) but those programs cannot remove this 75 Celsius thermal restriction for some reason.

Is there any way to report this to ACER or increase max temperature to atleast 85 Celsius?
I assume a BIOS update would fix this.

Thanks!
Best regards.

    Finally Fixed it. I undervolted the Rx560x to 0.975v on core  and that reduced the overall system temps to -10°c. Used Ryzen Master to set tdp to 22W (Default was 25w) . set Fans Near max using NitroSense. Now Cpu goes Max to 71°c and keeps around 3.00-3.1 ghz on all cores and gpu styas at 59°c. Strange thing is even if it hits 75 now  its will throttle to 2ghz for a few seconds and then again boosts back to  3.2ghz. Seems like i finnaly got a workaround to this

    Results after Undervolting and reducing TDp to 22W. Temps are way lower and Cpu is hitting 3.2ghz on all cores all the time.  No more throttling .

    Hello everyone!

    Just wanted to let you know I will no longer reply or update this thread.

    The reason is I sold my Acer Nitro 5 and bought the new Lenovo Legion 5 - that was the best fix for this issue.

    In case anyone wants a workaround for Nitro 5 CPU throttle issue, user @P25ani explained above how undervolting GPU and limiting CPU TDP can "fix" this issue.

    Have a good day everyone.

    Temperatures are provided by MSI Afterburner and HWinfo64. Displayed in Riva overlay ingame.
    So every change is real time and I can clearly see whats happening.

    @1337Braz
    open nitrosense and minimize it, then play your game after sometime when there is throttling minimize your game and check temperature in nitrosense immediately.

    Nitro sense is Always running.
    Temperatures match on both Nitro Sense and HWinfo64.

    75 Celsius causes 2.0GHz throttle.

    Reset what?
    Like Im certain this is a BIOS fault and should be fixed by Acer or with external program.. havent had any luck yet.

    Acer email support is not helping with anything

  • 1337Braz1337Braz Member Posts: 27 Enthusiast

    Did you find a solution im having the exact same problem with the same laptop
  • 1337Braz1337Braz Member Posts: 27 Enthusiast
    @yeeeeeeeet No, this cannot be "fixed" by any way. Tried everything. Even Acer Support cant help. Its supposed to be like that for protection... I assume only BIOS Flash would change this, but I wont do that.. we gotta learn how to live with it.

    Same  problem... Anyone solved it???


    When I try downgrading bios it works untill I restart windows then it downloads latest driver 
  • Robin038Robin038 Member Posts: 125 Enthusiast
    I downgraded to 1.16 and 1.13 but still the same issue... I think they wont fix it because they think it gets to Hot or something... Only 75 degrees... And i am sad because i updated the bios and my laptop is slower

    its a thermal throttling problem on a CPU-MB you need to give it to "Warranty Service for the change CPU" or MB or maybe unlock the safety things on mb
    note: i have the same problem with when degree going to 65C+ CPU stuck itself to 1.98 - 2.00 GHz (bios flash etc. not working)


    and i gived to warranty service.

    @ostkrov @Robin038 @WilliamRV @yeeeeeeeet
    Hey guys!
    Acer released new BIOS update this month (v1.18) and it seems I no longer have issues with CPU.

    Can you also check that out?

    Nvm .. its still not fixed.

  • KiksKiks Member Posts: 1 New User
    Hey, i've got the exact same problem
    Its been like, 5 months... a week or another i come here to check the status of this post.... I research sometimes, never found any solution. Calling the support here (Brazil) they told me that it is probrably the BIOS, but when reverted to the older version available, the problem persisted. 
    I just registered in this forum to give volume on the number of people with this problem, and i think that acer can fix it, that this isnt something difficult to do
    Anyway, ill continue to research, and hopefully find the solution...
    Please, keep this thread alive and, if found, post the solution here.
