Can you increase Skylake/Kabylake TDP Limit (i5/7 U series)

    If it is kept in thermal limits then can you configure it to bypass the TDP limit on AC Power, since there is a nice Convertible machine i have my eyes on, (ASUS UX360UA) but under combined load the TDP Limit causes CPU and gPU frequency to throttle, but the actual CPU is only about 60c, can we up the TDP to get the temp to 80c with increased performance (and noise)

    Not on a laptop chip (U or HQ suffix)

    shame really, i know you could on older ones (4th gen). it really is bad when the GPU and CPU are at load, 15w is never enough, most cooling systems support more.

    Upping the TDP on the processor could cause the motherboard CPU socket or power delivery system on the motherboard. Each motherboard (laptop, desktop, whatever type of PC) has a limit of the power it can deliver to the components included on it. Upping this is what happens (also) when you overclock the processor. Doing this on a laptop is suicide! You could overheat it and brick it good, or worse-case scenario draw so much power that a component fails with smoke/fire/big bang. That is, to be said, if you don't destroy the CPU in the process.
    The newer, smaller process nodes take less heat to destroy, so it is to be said that the older tech was a bit more durable years back.
    Do not increase the speed of your laptop CPU by 'hacking' it with a clock generator program, messing about in the BIOS, or otherwise bypassing/eliminating possible safety features that keep your laptop (hopefully) from an early demise.
    If you wish to mess about with settings, buy/build a desktop, stick gaming parts in it, and you will have plenty of settings screens to mill about in to your heart's (or wallet's) content.
    A laptop is what it is when you buy it. You may be able to add an extra HDD or SSD or another stick of ram, but most laptops are otherwise 'set in stone'. Start saving for a new machine, would be a good answer.
    Anything with an intel 4xxx cpu or better at 3ghz or better is good enough for this game provided it's got an add-in video card with it's own dedicated memory.

    it can't be that bad, it just annoys me since older laptops that are lying around me ran perfectly fine (i know its a different motherboard etc) at 34w TDP with a single fan AND a separate ATI GPU. Cooling in laptops nowadays is about the same as before, i get nice thick laptops (dinosaurs with Optical drives) and i do like a decent performing laptop, like i would like to run Minecraft PC edition on a laptop but with the iGPU in full swing there is not all that much power left to the CPU (hence it throttles). I was thinking maybe upping the limit to 20w TDP, then the fan could increase its speed and the temps all go up, i haven't seen a normal thick laptop with its CPU go above 75c. my old laptops can reach 90C under combined GPU/CPU load.
    I do have a machine (overclocked) and it is a good performer, but it is a shame that most laptops have U series CPUs and you have to go into Workstation/Gaming territory to get a CPU with decent TDP allowances (HQ series)
