Same problem here : https://community.acer.com/en/discussion/583137/acer-swift-3-sf-314-57g-cpu-throttling-when-using-nvidia-mx250-gpu I don't have usefull powerplans too because I install fresh windows 10 over Acer bloatware one. Does somebody have some work around to take them back from somewhere ? Because in default…

I solve the problem with throttle stop, but seems weird, the problem came from power issue. After using the mx250 two minutes under FIFA 20 the power for CPU go down for 5 Watts instead of 15 ! So CPU clock down to 600MHz ... I think we need a new BIOS which fix the issue ...

* Tu as quelle version de BIOS installée ? 1.09 ?

I tried with driver booster no changes. What is the workaround to install older bios firmware ?

@JackE I can't install older BIOS, that is bocked by installer which detect it is older BIOS version. @rafh13 have the same laptop and exactly the same issue it is not a problem with my laptop all have the same isue.

@JackE Yes I have the original firmware installed. I didn't update it, the laptop was sell with the version 1.09. If I check the support page of the laptop the 1.09 is the newer one. There is only two version available 1.09 and 1.07. https://www.acer.com/ac/fr/FR/content/support-product/8105?b=1 I tried to install 1.07…

@JackE @UserCV it is the same in balanced mode, CPU reach 72 degrees before frequency goes down.

@UserCV on afterburner I see CPU slow down around 70 degrees. I will check hwinfo tomorrow if I see some difference 

I will try with balenced mode, I will test it tomorrow. I have the original BIOS firmware 1.09. There is not any newer on support page for now. There one older on support page 1.07 but there is not changelog and I think I cannot install it because lower version.

This not solve the problem, I already set performance mode and laptop plugged with 100% battery but the CPU still go down to 1.5Ghz with the nvidia mx250. There is no problem with integrated Intel graphics ... I think maybe the Nvidia GPU produce too much heat then the CPU throttle ...

Oui le mode sata est apparu. Merci

Oui il faut se positionner sur le 2ieme onglet et faire control +S et SATA MODE apparait :)

Mon système n'utilise pas optane. Il n'y a qu'un seul disque SSD NVMe. J'ai bien crée un super utilisateur dans le BIOS, mais l'option SATA MODE n'est pas disponible.

Same problem for me with Acer Swift 3 314-57G and intel 1To SSD. SATA MODE is locked to "Optane without raid" and cannot be change even with setting admin/supervisor password. I posted today on french forum I will answer here if somebody give me some workaround. I think we need a BIOS update to unlock it ...
