I want to overclock my 7700k to 5ghz, but I don't know how. I cant find the setting, to allow me to type in 5000.00. I am using an Asus z270i motherboard. If someone can show me the steps to overclock it?

Also is there a problem with my cpu, since when I load up Prime 95, my max temp are about 72C, at 4.5ghz turbo. My gpu is an 1080 FTW, and it also goes above the default boost clock to 2000mhz, when doing a benchmark.

Not necessarily. You can have a SLIGHTLY unstable processor which causes data corruption so in general you should never be really close to the point the CPU is unstable.

And CPU's (and any processor) will degrade over time. The closer to the instability point you are the more likely you'll have issues in the future if your CPU degrades to the point (you could then redo the overclock however there's apparently a burn-in issue where the transistors get accustomed to a specific frequency but that's beyond me.)

My rule-of-thumb is to be at least 200MHz from the point it's unstable (and possibly drop the voltage as well).

Also, PRIME 95 if not...

The frequency of the processor depends on 2 settings:

1. The multiplier, which is unlocked on the 7700k allowing you to change it.
On most intel processor not ending with X or K this setting is unchangeable.
Meaning the only way to overclock them is by changing the bus speed, which severely limits overclocking.

2. Bus speed (BCLK)

In example of a 5 gigahertz overclock would be a 50x multiplier and a 100 megahertz bus speed.

100 megahertz x 50 = 5000 megahertz or 5 gigahertz

But as the last post said you should read a few guides before just typing it in.

You work your way up making sure each setting is stable with prime95.

May be of some interest.

I know, but I don't even know how to go up 100mhz. I have overclocked a Intel Pentium G3258

I downloaded prime 95 from:

Careful how you word that.

I was trying not to confuse him.

You are absolutely correct in saying all cpus even of the same model will be different in their maximum overclock.

But they all use those same 2 settings, bus speed and multiplier.

The only way to guarantee the highest overclock is by buying a number of cpu's and choosing the best one through manually overclocking each one and writing the results down.

But that is

1. Highly Time Consuming

2. Highly Expensive when we are talking about 7700k's


Being this appears to be his first time overclocking I would start slow and just work with what he has.

Preferably I would have started learning how to overclock with a less expensive cpu in case something went wrong.

But as long as you take it slow and read a lot of guides you shouldn't do any damage.

I have overclocked at Intel Pentium G3258 to 3.8ghz before but the way you overclock is different in this bios. All you do is type in 38, and then change the Voltage, and save. But now, its multiply, and bus speed, and I'm like What?

You need to read, investigate, learn.
Then do that again.
Then start to click settings.

Why do you want to OC to 5 GHZ in the 1st place?

Are you planning on running it at 5 GHz?

As others have said not all i7 7700K's will do 5 GHz at safe voltage so you have to go up in baby steps making sure things are stable at each step.

Also as others have said read a lot and do the research on OC on Asus motherboards, there is plenty of info out there.

The closer to the instability point you are the more likely you'll have issues in the future if your CPU degrades to the point (you could then redo the overclock however there's apparently a burn-in issue where the transistors get accustomed to a specific frequency but that's beyond me.)

My rule-of-thumb is to be at least 200MHz from the point it's unstable (and possibly drop the voltage as well).

Also, PRIME 95 if not aware runs the CPU more stressfully than any real-world usage. I would convert any video with Handbrake for at least 10 minutes whilst having 100% CPU usage (takes a few minutes to hit 100%). That's a more realistic worst-case.

I'd go with a maximum of 80degC, though Intel recommends closer to 75degC for long-term optimal reliability.

*Really rapidly diminishing returns going above 4.5GHz. Realistically probably somewhere around 0% to 5% gains at most, with closer to the 0% for most games especially with 2560x1440 or higher resolution which shifts the load towards the GPU.

I saw mention of DELIDDING?
Of course that voids your Warranty so is that worthwhile when frankly outside of a few points in benchmarks it's virtually IMPOSSIBLE to actually notice the difference. At least, just do a light overclock.

For example, you could probably tweak the MULTIPLIER values without modifying the voltage much or at all which would keep the power draw and thus temperature about the SAME as stock settings.

Now, I'm not familiar with newer CPU's but THIS is what I did on my i7-3770K.... Max Turbo was 3.9GHz (minimal load) and heavy load was 3.6GHz.

I just went into the TURBO section and change the 1-core, 2-core, 3-core and 4-core Multipliers to "45" (after trial and error) which gave me a 4.5GHz clock speed for all cores under load, though it still drops frequency and voltage when load drops.

May want to read THIS too:
http://www.pcgamer.com/intels-tells-core-i7-7700k-owners-to-stop-overclocking-to-avoid-high-temps/

Take that for what you will. I wouldn't be too concerned with a good liquid cooler, but if it was me personally I'd aim for perhaps 4.6GHz similar to what I did to my CPU above to help ensure the CPU will last many years. I've kept my i7-3770K for almost FIVE YEARS and I plan to keep it another five years if possible.
