Edit: Solved.

I have never overclocked RAM before and have virtually zero knowledge how-to! I want to quickly overclock my ram to get the most out of em, without burning their longevity life potential with a simple SAFE/FAST overclock.

I saw a video from Digital Foundry which showed Skylake/Kabylake processor performance scaling better in gaming with higher ram speeds, and thought id try and figure out how to go higher than 3200. ASUS recommended these specific ram models and everything is supposedly compatible for XMP 2.0 profiles.

I just bought these upgrades and have them coming in tomorrow (upgrading from an FX-8350)

CPU: i7-7700k Kaby-lake
Mobo: ASUS PRIME Z270-A
Ram: Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3200MHz C16 Desktop Memory Kit – White (CMK16GX4M2B3200C16W)

My questions:

QUESTION 1: What is the max OC limit for DDR4 3200mhz ram?
QUESTION 2: What is a safe OC for my ram cards?
QUESTION 3: Can I OC the ram with a few clicks? Is that what XMP Profiles is for?

Am I right to assume that ASUS PRIME Z270-A has set XMP profiles for selection to quickly call it a day.?

Just to confirm:

Okay so the XMP profiles allows for effortless OCing with many options to select.

I don't have to worry about messing with any other options? :love:

My motherboard says it supports up to 3866MHz (OC) so... would selecting the highest XMP profile option be fine and call it a day? no worries about heat or voltage- just clickity click? :eek:

3200 speed ram is stock 1.2v 2133 ram of higher quality that can reach 3200 speeds by overclocking to 1.35v.
You do this in the bios by selecting a XMP profile.
The xmp profile is imbedded in the ram chip and has the necessary info for the overclock.

While you might get even higher speeds by overclocking yourself, I would not bother for three reasons.

1. As you increase ram speeds, you also increase latency(cas numbers) which negate the benefit of faster speed.
2. The ram controllers of intel chips are very good at prefetching data from ram before it is needed so the benefit to real app performance or fps is minimal.
Here is a study:

3. spending the power budget on ram may keep you from getting an extra multiplier out of your overclock.

Here is what you can expect:
As of 1/13/17
What percent can get an overclock at a somewhat sane 1.4v Vcore.

I7-7700K
4.9 74%
5.0 56%
5.1 26%
5.2 5%

Do not bother much with ram overclocking.

My questions weren't 100% directly answered~ and I'm still confused~

It's so hard to find direct information regarding ram overclocking and not many seem to do it... maybe it truly isn't worth overclocking ram cards afterall.

According to Digital Foundry higher ram speeds increase performance for Skylake/Kabylake: https://www.youtube.com/watch?v=43g3OTK2AbE but perhaps that only applies to the advertised speeds you buy at.

Rephrased Question: Is XMP profiles used for effortless overclocking above my advertised speeds? or is it only for selecting/enabling my advertised speeds @(3200mhz)

Edit: BelowPost @SR-71 Blackbird - You've helped me out in the past quite a bit. Thank You! - I will just stick to my advertised speeds which is already more than good enough for my gaming needs. =)
