4790k Overclocking, now what?

[EvilWiffles]

So I've been overclocking my i7 4790k for awhile now...

Managed 4.7GHz at 1.233v so far stressed for 30 minutes. I stressed it before for like 5 hours at 1.249v and have been slowly lowering the voltage.

 

Temps reaching to 74c on H100i.

 

Where should I be trying to go now? I've tried getting 4.8GHz but crashes on stress with even 1.30v.

I haven't touched anything in the bios besides the cpu voltage and the multipliers.

 

 

It's been a great learning experience so far, so anything else I can attempt?

That's the voltage wall... You can basically choose between going for an Extremely high voltage for a slightly higher clock speed, or keep it how it is. <<<< Recommended

Yup, however, there are other settings that may help you get ot 5 ghz on 1.3 volts. Watch Jayztwocents video on that

Ah, pretty rough then. I'm pretty satisfied with my 4.7GHz though.

One thing that has been bothering me lately, why is it that the other cores have lower temps than the first?

Like my core temps > 74 71 70 65

4.7Ghz is the max stable OCon my 4690K as well. Like yours 4.8Ghz crashes under stress testing. Currently running @ 4Ghz cause I don't need anymore performance.

4.7GHz is where I run my 4790K as well. 1.263V is what it took for me to achieve happy stability.

 

Good OC, OP.

Their not being used as much as the first.

The other thing you want to ask yourself is:  Why am I overclocking?

 

If you are doing it just to get the highest stable clock possible (NTTAWWT - it's like mountain climbing for the sake of mountain climbing) then by all means check out things like the mentioned Jaytwocents video, and myriad other resources.  There are a bunch of other settings within the BIOS that may give you a better (higher) clock frequency than voltage alone. 

 

74 degrees is not bad, but if temps are the problem then you may need better cooling (which is what the extreme overclockers go to extreme measures for cooling.)

 

But if you are looking for something like the best performance in a given application then you really need to find a good metric for that application (May be nothing more than FPS in a given game) and test that after confirming stability.  Because you may find that other things - like memory clock (and/or BCLK), and GPU overclocking will give you better overall performance than raw CPU speed.

I do emulation and video rendering, so it's quite CPU demanding.

 

Can you link the videos you're referring to though?

It is for z87 chipset, but is also applicable to z97

 

In your case a good benchmark is to simply measure rendering speed for a given file or two.

I got a 4.9 @1.260V 24/7 OC, get's stupid hot after that but probably with a better cooler i should be able to get past 5Ghz
