    OH REALLY... it does not impact systems FUNCTIONALITY? Hey, the fans toggle on for no reason all the time, it is loud and annoying, the dGPU gets throttled at 75°c and standby is totally not working as it should be but that doesnt impact anything on the functionality of the laptop... I am done with this company.

    I tried. I really tried... I was in contact over 4 different tickets with Dell over the past 5 months about this. I also was/am in contact with Nvidia, but they dont really care or dont see what the issue is here, same as Dell. Both just always saying in the end "it works as intended". Both are incompetent and ignorant. The issue is, that this is kinda a bug in Windows 10 and/or the Nvidia driver. But Dell literally opened the box of the pandora for it, because of this stupid nonsense change they secretly made with bios 1.7.0.

    I honestly dont see any hope left. I am thinking what to do now, if I should try to get a 100% money back after 1 year using the XPS, or get a free swap for the 9580. Both is mostly not possible and denied by Dell.

    I feel so scamed, because of paying $2000 for this laptop. I am not rich. I cant just throw my money away and buy a new laptop every year like others can. I dont have a good job which can afford that. This laptop was an investment I thought of using for 5+ years.

    The only workaround right now is for the fans not to spin up all the time under Windows for no reason with AC connected because of these dGPU polls, is to deactivate the Nvidia GPU in device manager. This brings more issues into the boat though, because modern standby wont work then anymore. This is just an option, if you want to use the laptop with power AC connected all the time really. But then you have a silent laptop.

    I talked about it more in detail here:

    https://www.reddit.com/r/Dell/comments/bpzpbj/xps_15_9570_coil_whine_and_high_idle_temps/eo0i4pz/
    https://www.reddit.com/r/Dell/comments/bpzpbj/xps_15_9570_coil_whine_and_high_idle_temps/eo1au64/

    You have to enable the Nvidia GPU once and then disable it again after each Windows reboot, otherweise it creates a drain and the PCIe lanes wont shut down properly. I have made a start script for that on mine with delayed start and delayed HwInfo start. Also be aware that modern standby doesnt work if you disable it, it creates a 100% drain. Also be aware that you cant disable the Nvidia GPU like this, because it is then in a non defined state and creates a drain, this is not so important on AC but on battery.

    1. Download devcon.exe from MS, https://docs.microsoft.com/en-us/windows-hardware/drivers/devtest/devcon , https://superuser.com/questions/1002950/quick-method-to-install-devcon-exe , extract for 1809 from this cab https://download.microsoft.com/down...stallers/787bee96dbd26371076b37b13c405890.cabfilbad6e2cce5ebc45a401e19c613d0a28f and rename it to devcon.exe.

    2. put it somewhere like I did here, and then create two shortcuts like this:
    "C:\Programme (frei)\devcon.exe" enable "PCI\VEN_10DE&DEV_1C8C&SUBSYS_087C1028&REV_A1"

    "C:\Programme (frei)\devcon.exe" disable "PCI\VEN_10DE&DEV_1C8C&SUBSYS_087C1028&REV_A1"

    The device number you have to look up for yours in device manager:

    right click copy. example: PCI\VEN_10DE&DEV_1C8C&SUBSYS_087C1028&REV_A1\4&1CFD4D04&0&0008

    cut off the part after rev_xx

    Then go into Windows task planer and create two tasks. First enable the dGPU after login and around 30 seconds delay, the other disable with 40 delay:

    You can put the shortcuts into task menu too: https://i.imgur.com/IN2m31z.png

    Check if the shortcuts work by just run as admin and then have device manager open.

    Then I also have HwInfo started too after 50 seconds, with "custom auto" fan mode:

    put OpenFanCtrlMin=1 in hwinfo64.ini

    Enjoy silent XPS, in combination of disabled turbo, speeed shift max limit to 33, or turbo short 25 and long 15 watt setting in TS.

    Any news on sound problems (livestreams, podcasts, youtube)? I made all updates available and the sound is terrible. It sounds like the laptop is broken...

    The bios of this laptop is awful. The 9570 is the worst laptop that I have ever owned and now I try to sell it and buy other...

    Let's change the mood with something positive.
    Dell corrected what they messed up some time ago when they forced the vivid, rich colors, and have now released a new Intel graphics driver that can change the color gamut to "Natural colors" from the current "Vivid colors". It's a new slider in Intel Graphics Control Panel, in Display, Color settings.

    And if you're already updating the drivers, there's a new Realtek audio driver as well, that "improves the audio in VoIP applications."

    I went back to the 9570 since there really isn't anything else that meets the requirements that I have. I lucked out and found one that undervolts great.

    I'm curious, how much can you undervolt your new 9570? I'm running -175 on Core and -145 on Cache. I've read somewhere if you undervolt too much the performance actually decreases?

    On another note, I changed the SSD to the new 1TB Samsung 970 Evo Plus, and upgraded the RAM to 32 GB. But I also bought some 1.5mm pad and padded the RAM, PCR, SSD and also put the big pad over the VRMs, connecting them to the sink. It all runs cooler now and it seems the CPU can sustain higher frequency for longer time.
    I'll post some photos and benchmarks to the other Dell XPS 15 9570 benchmarks + temps thread tomorrow.

    I can run it at -160mv on both cache and core. I've never had much luck undervolting the core more than the cache though. What should happen is if the core is undervolted too much, it just won't reach as high of an operating speed, downclocking itself.
