Please EVGA take it easy on the marketing hype, I understand it is normal to hype one's products, but claims like these are untrue and misleading.
I for one have the SC17 1080 and am happy with the build quality and aesthetics.  However, for a laptop built "with performance and overclocking in mind", I am disappointed since you limited the power limit to 60W.  I use the machine primarily for rendering and such, and when under load with the 60W limitation, 4.1GHz is the maximum possible before power throttling.  Please, please EVGA, since you made such big claims on your marketing, please release a Bios or EC firmware update for my machine which at least increases this limit to 70W.  My thermals can handle it, thanks to the better heatsink than the one on the 1070 model,  and so can the power supply.

    Have you considered that there are power delivery components which cannot safely operate at greater wattage which you are unable to monitor the health of in order to determine their ability to handle greater wattage? I think it is very unlikely for a company to impose limits for no reason. Such decisions are usually backed by engineering data.

    Of course, but then don't make wild claims on their marketing.  MSI, Alienware, Clevo, Asus and even Aorus can clock higher because of the relatively low power limit set for the SC17.   I totally understand when it is set by design, but i expected greater flexibility when unlocking the Bios, I don't care about warranty at this point, since I will be repasting soon as well.  Different than the other brands cited, the power limit seems to be controlled by the EC firmware and not the Bios.  Either way, I am happy with the machine, just wish I could get more performance out of it considering the hyped up marketing for it (the world's first true overclocking laptop.).
    Marketing the laptop as overclockable should suffice, instead of claming it was designed for enthuastists, overclockability and performance, just because it has a fancy but very limited GUI Bios and CMOS battery reset on the case.  4.1GHz on all cores is good but far from what I expected from their product page.
    I am pretty sure the components can handle some more wattage, unless they used lower quality components compared to other notebooks (which I doubt), since I have had no issues with this on others models over the years.  All in all a very good well built machine.

    Found a workaround to the very low power limits . Cinebench 980 at 4.4GHz all cores.  Any higher and I reach thermal limits of the stock paste, so time for a repaste.

    Happy camper now that I managed to bypass the PL limit set by the EC firmware.

    Hopefully the happy camper won't have a laptop campfire.

    Hopefully the happy camper won't have a laptop campfire.

    Thankfully the heatsink is a lot better than on the SC17 1070, and temps were max 91C.  Now if you think mosfets and other components might blow, then I would say it deserves to go the campfire, highly unlikely since EVGA wouldn't put a cheap motherboard in their notebooks, eventhough it is a HM175 instead of the CM238.  All other i7-7820HK notebooks models that I have tested or friends have, handle 4.3GHz as a daily runner no problem, except for thermals with stock paste.  Most need a repaste from the factory job, but the SC17 is surprisingly good at that.  The PCH temps are amazing, especially compared to the Alienware 17R I had, where Dell thinks that 95-99C is totally normal. Keep in mind that the SC17 1080 has a 300W PSU, not the 240W one of the 1070 model, and the TDP of the 1080 card is limited to max 180W, not like the 200W limit of the MSI or Alienware with overclocked vBios, so there is plenty of headroom for an extra 10W or so for the CPU package.  That being said, I would only use higher clocks for encoding and benchmarking, cpu intensives games max 4.2GHz.

    Yes, the motherboard is what I am concerned about; like I said earlier. There is rarely a limit imposed for no reason. ;)

    What is your stock vcore versus overclocked vcore? If from 3.9 GHz to 4.1 GHz you used approximately 15 watts additional, from 4.1 to 4.3 GHz, it seems to me that you are likely using 20 watts additional on top of that original additional 15 watts, or more.

    After the spectre patch, cinebench score actually went up for 4.4Ghz.  Haven't compared with other benchmarks though.

    I like campfires. Drinks all around.

    Waiting for the bios programmer to arrive, to be able to flash the modded vBios increasing the TDP of the GTX1080 from 180W to 200W and have a big bondfire.

    I think your concern is that others might get a bad idea and do the same, but trust me, not easy to bypass this PL limit, the hardest I've seen in a while, since the settings in the unlocked bios do nothing.  This laptop comes with presets, the superclock preset is 4.0GHz on all four cores, and EVGA set the Vcore offset at +100!  I guess some cpus had a losing hand at the lottery, so to be sure that all notebooks would run at those clocks preset, they opted for a big overvolt.  Which means that at 4.0GHz, the VID is at 1.235V.  On my particular machine, I can run 4.3GHz at 1.215V,  which is not great, but hey what to do.  So the watts used is not that much more, around 3W.   If I adjust the voltage for the superclock preset, 4.0GHz is stable at 1.135V, then the difference to running at 4.3GHz is around 12W on full load with AVX.
