Hi i want to overclock my i5-6600k. i have an asus z170 motherboard. I want to overclock to 4.5 or 4.6 if able. I know it can hurt parts and decrease life time but how long can i leave it on a 4.5 ghz overclock before it will start doing damage? sorry for all the questions im new this.

ok, first of all, while you can theoretically overclock on a z170 motherboard, you really, really don't want to. The second thing is that all silicone is different, and a cpu that can run x.x volts all day will watch the one next to it blow up at that setting after a few minutes. You start at the minimum increase, and you run it at that for a length of time (when I'm playing with overclocking I'll spend a week at each setting, watching temps and performance).

Here's what you'll find out in the end: It's risky, and not worth it. The net performance gain is minimal (again, this is all my opinion: others may disagree, your mileage will vary)I do it for fun, but I have a computer dedicated to just playing around on, and when I fry a...

I cry a little, then buy another one. The cheap boards (and most z170 are cheap boards) don't have the volt regs/components necessary to handle consistent overclocking.

Save your pennies and buy an i7-7700(k...sure, why not...) if you want to go faster. Buy a better video card. Get more faster RAM. don't overclock...

Look man overclocking can not do any damage as long as you are in safe range as specified by the manufacturer. Search google and read authentic articles to get a better overview. Now when you overclock your cpu you are telling it to do more on off sequence in a second and to do that it will need more voltage than the default. Now when you increase voltage it will generate more heat as a simple law of thermodynamics as it is doing more work.
Manufacturer specifies a certain voltage cap for safe long term operation of your cpu. During ocing your goal is to increase the clock speed and voltage by small increment to hit the wall where increasing voltage has no impact on clock speed i.e. u can not increase the clock speed by increasing voltage.
Lastly before doing anything ensure you have top of the line cpu cooler aio or air and search google to find the safe voltage limit of your CPU. But don't start from that limit, never ever. Try from your base and gradual increment and stress test it for 1hr at least. See some videos in youtube popular channels how to.

And lastly do it on your own risk. On a good mobo and other components if you fry your cpu by overclocking then don't blame others or say overclocking is bad: it means you are stupid enough to study less before jump into the water. As long as you know what you are doing and what are the precautions you need to take it simply can not do any harm. I have overclocked first time in my life a non k i5-3450 chip to 3.91Ghz and till date (4yrs) it is working fine without a single BSOD for cpu. And I know many others are also doing fine. So do your homework very well and you will pass in your exam.

oh, yeah. and a top of the line PSU. and know where that wall is...oh, wait...you can't know where that wall is until you hit it!

If you have one computer, and it is your day-to-day computer, and you can't afford the downtime or the money to fix it when it blows, just don't do it.

I mean:
Say for my cpu it is 1.425v max for day to day use as per amd. I will push to add more clock and volt say upto 1.450 but not a single increment more. If I see that in the range 1.41 - 1.45 I am not getting any benefit then I will reduce the voltage equal or below 1.425 and stick with the stable clock for that volt.
my cpu can work 1.35v - 3.85 Ghz
but to touch 3.95 I have to throw 1.40 volt and after that to get 4Ghz I need beyond 1.425v.
So my stable oc (max) will be 39.5@1.40 volt much below the amd specified 1.425 for daily use. As simple as that. But I have spend almost 2 weeks to find this optimal setting. Yes it is not easy and as long as you can not spend longer time don't try it. OC is not for everyone.

I wanna overclock to help my streaming and games i play. Ive heard that overclocking to 4.6 is really safe on an i5-6600k. but one question, whats the life span with overclocking vs not overclocking. is it like 10 years vs 3 years?

In one line: No one in this earth knows this answer. But it is not like 10 vs 3 yrs for sure. If you do it properly it may be 10 vs 8yrs. but assumptions alright not have any database to confirm it. But your cpu will become obsolete much before its life is over. Most of the time, your mobo dies first than the cpu. If you are planning to use this pc for 5 yr more: no problem at all but ensure you have a good psu and cooling for all cost. But strt from base as there is no guarantee that you can hit any targeted speed as becs of silicon lottery.

I've never had a non-overclocked CPU fail, and I've never actually replaced a non-overclocked CPU, either. They don't so much wear out as get obsolete (and turned into Linux boxes...). I've seen over-clocked systems start to fail (you get crashes, black/blue/green screens of death, odd glitches, etc) as soon as one year, others really do seem to go on forever. The term is "silicone lottery", and it basically means that no one knows how a particular bit of silicone will hold up to any specific overclocking.

An example: a CPU may overclock to the top of the "safe" range, and run nice and cool and stable there. That is no guarantee of longevity: it may fail after a week or a year or 3 years. It may fail suddenly and completely, or it may fail slowly, giving occasional errors that eventually lead to the various colors of death screens. There is literally no way to know. The same for a chip run at the low range of overclocking: just because the volt increase is minimal doesn't mean that the chip will last a long time.

The statistics are complicated, but manufacturers base their warranties on projected failure rate, and they set their warranty lengths in the fat part of the performance/life-expectancy bell curve. You are literally going outside the norm, into the proven increased failure zone, when you overclock.
