I7-4790k overclocking

[Jordan1417]

Just before I get into the overclocking, my system is running

Mobo: Asus Z97-A

GPU: Asus 780TI

CPU: I7-4790k

Cooler: H100i GTX

RAM: Crucial Ballistix Sport 1 8GB stick 1600

PSU: Corsair HX 750

128 Sandisk SSD (Boot)

1TB WD Blue 7200rpm (Storage)

(Hopefully I didn't forget anything)

 

So I started overclocking with Intel extreme tuning utility and so far I have go to this stable.

The only thing I have touched is the core voltage and I set it to 1.39v and I have core 1&2 at x48 and the last 2 cores at x47

Temps are looking good at the end of a 5 min stress test it runs about 70c

 

If I try and push it farther it ends up freezing up and restarting my computer. I haven't touched the resource cache ratio or voltage because I am not sure what it does.

Any help or suggestions on pushing the cpu farther would be appreciated as I really don't know what I am doing lol. 

Also I am wondering what is the core voltage I should stop at as I do not want to harm my cpu.

 

Thanks in advance!

1,4v is way too high for me^^

got a stable 4.7ghz at 1.3v,sadly i lost pretty hard in the silicon lottery and can't go much higher

1.365 @ 4.9GHz, What I run 24/7

try that.

1.4 yes quite high agree with McHox... my sweet spot would be 4.5-7 Ghz since you dont need to increase core voltage by TOO much Definitely overclock but not so much by pushing your voltage to 1.4, 1.3 is a bit high but should be fine I guess

[thekeemo]

push up the clocks and voltage your fine to 85c

Im at 1.28 @ 4.8

Wow thats great

Nope. anything above 4.8Ghz seems to just insta crash. Right now I am running 4.7 at 1.32v and it seems to be responding fine. I am going to try to get 4.8Ghz at the lowest voltage possible.

Wow thats great

with 212 evo....

have you tried it in the bios...

if not you had horrible luck in the silicon lottery

No way I wonder what my 6700K with be quiet! Dark rock pro 3 will achieve with like 7 extra case fans XDDDDD

I tried 4.8 at 1.365 and that is the best I could get it. 4.9 is a no go lol.

*previous post still stands, you had no luck*

So it seems. Thanks for the help!

I just got lucky with my chip.

I have to agree that 1.39 or 1.4v is way too high and you'll definitely start to run into heat issues. I was running my 4790K at 4.6GHz at 1.25v and I was perfectly happy with that result. Sure I probably could have pushed it to 4.7 or 4.8 by increasing the voltage to 1.3v+ but the gains from a 200 mhz bump is not worth the potential instability and extra heat IMO. Even at 4.6 GHz and 1.25v on a Corsair H110i GT with 4 fans in push-pull, I was still getting core temps from 65-70C on max load.

I forgot my OC but I think I'm running 4.7 on 1.28v? 

[Br3tt96]

I usually rock 4.7ghz @ 1.20v, but I'm currently running 4.8 @ 1.225v.

Silicon gods shined upon me.

I have left it at 4.7 at 1.3v. Silicon lottery was not in my favor lol. My h100i gtx keeps my processor at about 58-60c on max load.
