    RAM: 8gb 2133MHz vs 16gb 2400MHz?

    Is it worth it? I dont even know if my P651 (specs in signature)supports 2400 or downclocks it? I see that in some games CPU is the limiting factor. After studying a lot of youtube-videos, in several games like Witcher 3 just going from 2133 to 2400 on a high end GPU fps increases 5-10%, Ram also gives a few percent gain. Anyone tried this on a skylake-setup?

    RAM doesn't affect performance THAT much when jumping from 2133 to 2400. If you were going from 2133 to 3000, then yes, the performance spike would be 5-10%. But for a 270MHz increase, expect 2-3% at most. Keep in mind that with the ease-of-use of youtube, there are hundreds of fake and intentionally misleading videos by small channels who aren't really knowledgeable and just present biased and fraudulent numbers.

    I didn't read the whole thing but from the looks of it, the majority of real world applications that are NOT bandwidth-hogs benefit by 1-4%. And the biggest difference is going from single channel to dual channel (which we know is a MUCH bigger difference than clockspeed). Just buy the cheapest 16GB 2x8 kit you can and don't waste money on things which won't affect you.

    Fast ram is always the cherry on top of an already kitted out system if you have the spare funds :)

    But does 6700HQ skylake support 2400? :)

    Officially no but it would be odd for it to have issues at such a low speed.

    Intel mobile H series chipsets only work with 2133/2400.

    Officially with 2400Mhz added in on the latest chipsets.

    Official and what you can actually set are not always the same however. I run 2133mhz DDR3 on my 4xxx gen CPU system and 3000mhz DDR4 on mt NP9873.

    But that's a modded BIOS I presume? :)

    Now yes, but it worked on the standard sager BIOS too with some prodding (since it was 3ghz, 2800 and below had no issues generally).
