    It looks like no one is getting the insane amount of throttling I am getting. For me all the throttling is very noticeable and makes gaming impossible to play. Also I noticed that if I am in game and the cpu is throttled and I close a game and go back to my normal tasks of web browsing it takes 5 minutes for things to actually work again. But if I close a game before throttling happens I can go back to web browsing instantly. So my conclusion is that I must have gotten a unit that had the worst paste job in the world and or some other issues. So I will be returning my unit and getting a different computer.

    Cool thanks for sharing buddy. Not sure I wanna work around the problem with disabling my CPU turbo mode and DTPF as it who'll definitely impact game performance with a GTX1050 but may help others! Think I'll prefer the hardware mod from @iunlock for fixing the issue at source

    Try with these settings

    Preferred graphics processor: High performance
    power management mode: prefer maximum performance
    shader cache: off

    Dell has a KB for this:

    http://www.dell.com/support/article...under-sustained-100-cpu-and-gpu-loads?lang=en

    2. Why is this happening?


    The XPS 9550 and 9560 are the latest, thinnest and lightest workstations Dell currently supports with the latest technology available.

    Due to how thin and powerful these systems are, the design combines the CPU and onboard GPU cooler into one unit. If both the CPU and the GPU hit 100% load and sit there for sustained periods of time, while still capable of handling heavy CPU and GPU computations the system will throttle the CPU in order to ensure the system does not overheat.


    If you require something that can sit with sustained heavy CPU and GPU loads, then you may want to look at a more specialised workstation from our Precision range.

    But I love the note they mentioned:
    "Note: Please be aware this article also applies to the Precision 5510 and 5520 Mobile Workstations. These systems share design features and components with the XPS 9550 and 9560 Mobile systems and behave in the same manner."

    I just ordered this from Dell from their Outlet. I just missed the CR unit and settled for the Scratch & Dent. I thought the worst issue on this was the red/pinkish shift on the 4K display which I wanted to to see first hand and return it if it was that bad, but this just makes things worse. I planned to use this for development with vmware and some light gaming, like GTAV.Skyrim/Oblivion and BF2 which I think it would be fine with the latter games, but not so much with GTA V. I really wanted this machine because of the glossy screen, which is rare today, along with higher end components, but I'm unsure of longevity with so much heat being generated. I got the 4 year premium support for $150, thinking, I could amortize this machine at around $368 a year and have that warranty in place in case if it does break down, if I get 6-8 years out of it, I'd be happy. I currently have a M4400 that's about 8 years old (also from the outlet) and works great, just had to replace the HDD with an SSD. But it seems like the new Precisions are much more expensive with bare bone HW for under $1300 in the outlet compared to years ago + from what I read, the panels being used are not good. I also recently bought a SC17 that I gave to my son, it's a great laptop, but EVGA does not sell extra power adapters, nor batteries any more which I really want. I was surprised Dell only currently sells the power brick for the 9550, but no battery for it? Looks like you have to go to a 3rd party vendor for it?

    Anyways, I'll see how this unit works out when I get. If I fire up vmware and I start to see throttling with heavy database usage in postgres, I will be returning it. Too bad they just can't make a bit thicker like my M4400 and have better thermals. Also, I'm sure they could design it where the battery pops out like older Dells. This is an unnecessary design probably borrowed from Apple. Personally, I'm not crazy about the design of the 9550 and still love the look of my M4400, I really like that slab look (except for the silly looking top lid which is wavvy.) Ugh. After writing this, I guess I really want a Precision with the same specs (Skylake so I can install Windows 8.1 without the MS mafia telling me I cant with Kaby, the 4K touch IGZO panel) AND price of the XPS 9550 :)

    For what it is worth, if you undervolt and repaste, your machine will most likely be able to run intensive tasks all day and night. I repasted and undervolted my CPU by -140mV, GPU by -100mV (+100MHz overclock on Core, 200MHz overclock on memory) and I can run both a 100% GPU and CPU 3D rendering load with no throttling, CPU gets up to about 85 degrees with this workload, GPU about 70-ish. High temps, but this is taxing the system to the max of course.

    Thanks, that's what I was going to do. My concern is, it's an older used machine, and probably had turbo enabled with default auto voltage...meaning, it could require more voltage (less negative offset) than if new and starting off with a lower voltage using adaptive -- my EVGA SC17 can do -120mv easily and keeps cool. But if I taxed that system with turbo for a year, I'm not sure if I could get away with that undervolt when in idle if I never started with an negative offset voltage to begin with. I'll try though! I'll try the re-paste too just in case if the temps are not good either. I read the threads on the pads and they got mixed reviews/results/performance, so I'll just stick with a re-paste if necessary. Thanks again for your suggestions.

    Also, do you have the 4K model? Do you have any reddish/pinkish color shift on the display?

    I just got a 9560 4K and there is no red/pink tint what so ever, the colors are excellent.
    an tinted panel I think you should try get replaced by Dell, I would not be able to use a machine if I would see an annoying tint all day.

    CPUs don't degrade though, so the heat issues you had with your previous laptop stem from elsewhere. Perhaps the thermal paste dried out, which starts insulating the heat from the CPU causing higher temperatures. Dust is also a major issue in laptops. Maintenance for your laptop is very important if you want it to keep running at its max speeds.
