Intel i5 4690k stable overclock?

[led zeppelin96767]

so i have been planning on overclocking my CPU (i5 4690k) to 4.00ghz, and will 1.300 vcore be enough? and also i have a cooler master hyper 212 evo.

[RollinLower]

that might even be way too much. to be honest though, only you can find out what a nice stable overclock would be for your specific CPU. not every CPU is created equal, not even CPU's from the same lineup!

 

so yeah, try setting an overclock on stock voltages first, then if it becomes unstable up the V's a bit and rinse and repeat.

[led zeppelin96767]

well how can i check my voltage then?

1.3 is way too high as a starting point. Especially for a low OC of 4.0ghz. And even more so with a humble cooler such as yours.

 

Try 1.2v, that should do it. In fact, it should even be more than you actually need.

This is correct, and why they call it the silicon lottery, but voltages do often correlate. 

 

I would not recommend going above 1.4 on the 4690k, that much got me to 4.8

There isn't really a set value as it will vary between all CPU's how far it can overclock but 4.0Ghz should be quite doable, try starting out at 1.300V and do some quick stress tests to see if its stable short term. After you can start dropping the voltage incrementally and stress testing each time until you see at what point your system isn't stable. At that point bumping it back up to the last set amount would be a good idea, and to start doing a long stress test run. Of course make sure your temps are good and to try and keep them <85C.

Man... I remember the time where people would say "don't go over 1.3v!" for Haswell CPUs.... now Skylake came along, with it's higher voltage tolerances, and people indiscriminately say 1.4v for Haswell as well.

I am saying this because Mine became unstable above 1.4V, and Intel's recommended max isn 1.35 i believe. 

 

either way, you wont need nearly that much for a 4.0 or 4.2 Ghz OC

[led zeppelin96767]

well the thing is how do i know when its too unstable? 

[Techicolors]

speaking of overclocking a 4690k... kinda highjacking this thread lol

 

but i have mines clocked to 4.5ghz at 1.3v. i want to push to 4.6ghz (have sufficient cooling), so i add some vcore but the system refuses to boot into windows. i dial back to 4.5ghz... everything's fine. does that mean i hit the limits of the silicone?

ok so you reckon 1.3 would be enough for over 4.00ghz?

pretty much. though it can differ with your system, and silicon lottery 

[led zeppelin96767]

ok guys I'm going to try and overclock to 4.00ghz with 1.200 Vcore so wish me luck, I will be back to let you know how it goes

If your PC BSODs, your stress test stops saying there was a failure, you experience weird crashes.... then youa re unstable.

Well, you've gotta hit the limit eventually, don't you think?

Just in case it wasn't a typo and you actually didn't know it.

kinda stinks that i got a spanking new cooler and now my chip can't overclock much lol. when i pushed for 4.6ghz i went higher than 1.31v and it booted, but i ran a stress test and the system locks up.. 

 

ah yeah that was a typo

ok I'm back with 4.00 GHz 1.200 vcore, so far not noticing and issues, let me boot into windows fine, what stress testing do you recommend? 

ok so in speed fan and GeForce experience it's still saying I'm at 3.50ghz? did I do something wrong?

Intel's XTU, and some gaming (or any task that uses the CPU heavily)

 

Prime95 for some serious stress testing. though it's tougher on Haswell chips, but i think the recent versions fixed this issue

use CPU-Z or hwmonitor 

[led zeppelin96767]

ok so CPU-z says I'm at 3.50ghz??

did you go into BIOS and apply your changes?

in my bios it says i have 4.00ghz 

and I applied it twice And its stills say I have 3.50ghz

Is CPU-Z reading just the base clock?  Put a load on the CPU and see if it boosts up to 4GHz.

[smokefest]

It will shows 3.5 GHZ all the time cuz its the manufacturer official stats.

 

Where you can see your actual OC is exemple in Real Temp , there you will see ur real GHZ...

Also in cpu-z you will see it too but you have to check the bottom section, not in the middle where it states your manufacturer stats..

 

Also go read some Guides as you seems to not have lot of knowledge on overclocking..
