Oh I´m aware of XMP, but:
1- It doesn´t guarantee stability. It only automatically adjust voltages so that you don´t have to do it manually.
2-You did so much research you couldn´t even scroll down.
"
Altering clock frequency or voltage may damage or reduce the useful life of the processor and other system components, and may reduce system stability and performance. Product warranties may not apply if the processor is operated beyond its specifications. Check with the manufacturers of system and components for additional details. For more information, visit:

Quote from Inte´s XMP page.
I don't know if you're playing dumb to frustrate people or just dumb in general, but what you're looking at is the USA Intel page that has that asterisk for liability reasons. The Canadian webpage does not include that asterisk because well... we aren't as sue happy as the states. FYI, the link I provided is a .ca ended page.So yes, I did scroll down to the end of the page.
Have you ever actually used XMP? Unless your motherboard can't for some reason interpret the XMP values properly into their respective adjustments in the BIOS, you're almost always going to have that ram working at the spec the XMP shows. Instability due to XMP is not because of above specified clock speed as listed by Intel, but rather by
- Inappropriate configuration by the bios
- faulty hardware in the first place.
Have you ever for a second think how that warranty works on the processor? Intel for legal reasons write that if you overclock your processor, you void you warranty. Let's step back for a moment here and see how they're going to find out you "overclocked". Well, unless you're stupid and overvolted the bajeeberz out of the processor, way above regular operating ranges, then well yeah, Intel will find out with a visual inspection. But if you aren't stupid and just overclocked within reasonable ranges and not bumped your voltage to stupid values, then that overclock isn't really detectable.
If you haven't figured it out yet, you don't go above the specified voltage for the ram to get the overclocked speeds. DDR4-3000 runs at 1.35V. Just like DDR4-2133 runs at 1.35V.
You also use their wording
Altering clock frequency or voltage may damage or reduce the useful life of the processor and other system components, and may reduce system stability and performance.
as if it's 100% going to cause instability. Perhaps look up the definition of "may".
I've had my Core i7 920 for 6 years (I recently swapped to the W3690), consistently pushed to 4.0ghz (stock is @2.6) for the 6 years. I've also had the ram bumped to 1600 when the processor's supported default is 800/1066. A stick of RAM failed on me half a year ago... guess how that was sorted out? RMA'd with Corsair and got a new set within 3 days. If you consider that "instability" and reduced useful life of other system components... sure. But that's really only on the RAM side. The IMC isn't going to fail on you for that. The robustness of the IMC is primarily due to the silicon lottery. Some IMCs of the same model processor can support higher overclocks than others, but in the skylake's k-series chips, those are well above the 3000mhz mark. Meaningless ceilings for most people as there's not a lot of RAM kits above 3000.
If you still feel that going above 2133mhz spec for DDR4 is going to cause instability, then feel free on being wrong.
