    Hi,
    I have just bought the UX430UN, what to say .. it's a great machine but the pwm problem is there: after a few minuter my eyes get tired and I start having a litthe headache. I usually don't have this kind of problems but, as you said previously, it's subjective.

    Do you think that this problem could be fixed with a new firmware bu raising the default LCD frequency?

    I have found on youtube a link to an utility that seems to fix, at least partially, the problem. I don't know much about it, just that it's 3 years old and I was unable to install it. The link is this one, let me know what you think about it please.

    https://github.com/tpurtell/PWM

    Many many thanks in advance.

    P.S. If you don't have problem with pwm this is a REALLY good machine, quiet, well build and powerful.

    Hi Antonio,

    Welcome to the forum. There are 3 programmes which you could use to control the PWM frequency in your laptop:

    https://github.com/tpurtell/PWM

    https://github.com/dmytrov/IntelPWMControl

    https://github.com/Kappa71/PWM

    Ideally you want to increase it over 400hz or 500hz (according to this study https://www.dial.de/en/blog/article/ieee-1789-a-new-standard-for-evaluating-flickering-leds/). The optimal amount depends on the % modulation. Check graph in pg 44 here (http://www.bio-licht.org/02_resources/info_ieee_2015_standards-1789.pdf)

    However if you use any of these, it is uncertain what effects it might have on the lifetime of the laptop screen.

    Another alternative is to operate at maximum screen brightness where there is no PWM and use any of these utilities to dim the display:

    https://techsensitive.com/screen-dimming-utilities-for-windows/


    Also according to a review on amazon, the PWM does not happen if the laptop is connected to AC, although I doubt its the case. Can you check?

    In my case I changed my mind on this laptop and ordered it. Apparently I was wrong regarding PWM effects for me. I opened my old laptop zenbook ux32vd and it had pretty aggressive PWM, at around 180hz, which is quite low. I used it for 4 years and never noticed the PWM at all. So I wasn´t aware about this "problem" until I looked into this forum. So it seems I am not affected at all.

    I am receiving my laptop soon. I think its much better value than the XPS 13 quad core, double hard drive space, RAM, larger screen and GPU, for the same price, and almost same weight. I ended ordering from amazon because costco was charging a 60 dollars fee for being non member (they should say this up front), plus shipping plus taxes, amazon ended up being cheaper. And I like the easy amazon return policies. Will post a full review soon.

    Thanks a lot for your help Alejo,

    I have tried to use these two utils:

    https://github.com/dmytrov/IntelPWMControl
    https://github.com/Kappa71/PWM

    but they don't seem to work properly on Windows 10 (64).

    I have also tried the two dimming utils you suggested, they're quite old but still quite effective (no startup settings though).

    I am trying right now this one: Iris (https://iristech.co/), it is highly configurable and free (a pro version is available too and has loads of features).

    If you or someone finds beter solutions to make the ux430un diplay more 'relaxing', please let me know.

    So the new bios should have been released in December to fix the GPU 73C throttling. Anybody know if it is still being worked on? I cant see any new bios on the support page for the UX430UN. Im thinking of buying this laptop, but the throttling seems to be dealbreaker for me. Also, how is the fan noise in idle or light load? Previous zenbooks had very aggressive fancurve and the fan was on all the time.

    @Kjetil95 Probably a bit ambitious to release anything end of December like they suggested in that forum post referenced a while back... I reckon within the next week or two (when things have calmed down from CES)

    Koog.

    I'm still throttled of course, but I'm using a compact cooling pad when I game and my clocks are pretty stable at 1400mhz. I've overclocked the ram by 1ghz with no issue, it must be factory underclocked. I think my XTU profile helps, no short term turbo, 12w max package tdp, and -.80mv on cache and core. While gaming this limits all four cores to 2.88ghz from the 12W package TDP, but keeps the CPU temps looooow.

    I think Xiaomi Mi Pro might be a better choice for me. Same specs and has no problems with throttling and can obtain max clocks on cpu and gpu without any use of cooling pad. I can get it for the same price as this. I will wait and see if asus release the bios update, but even then I am a bit worried about fan noise. I currently own a zenbook ux32ln and it has a fan that is active all the time, even on idle. I hear this one is the same. Also I have heard that the cpu reaches 95c on max load, no bios will fix that. I think the laptop have insufficient cooling for these components
