4670k OC Temps?

[acwilson96]

I am running 4GHz on a 4670k on 1.2V as my initial overclock. I am getting a max temp of 58c after 5 mins of 100%.

I know haswell fluxuates alot but what temperatures are dangerous for a 4670k on 100% load?

[acwilson96]

Haswell runs pretty smoothly at pretty high temps, 80 degree's and such.

I suppose the question im asking is what are the average temperatures for 100% load on haswell(I know everything is different). Because I hit a max of 58c on a 10min stress test and right now at idle im at 33c 4GHz 1.2V, and wondering if I can crank it up to 4.1GHz off 1.2V, or should I do 1.25V and 4.1GHz then bring it down if needed?

Your ceiling should be approximately somewhere in the 80-90c area, depending on what figure you're comfortable with.

[acwilson96]

What cooler are you running firstly?

Also always try bump up your OC until you lose stability then bump up voltage accordingly, the temps your running are quite fine but

I have an H80i. I tested 10 mins with Intel's stress tester and I am going to test around an hour with AIDA64.

[acwilson96]

Yeah you should be able to squeeze abit more out of it comfortably. Try bumping up your OC before you change voltages and keep going up until those temps hit the 80 degree mark.

So you think I should keep the same voltage and keep bumping OC until it fails, then bump voltage until it works, then rinse and repeat until at target and temp < 80c on 100% load?

 

P.S.

15 mins into AIDA64 stress test and averaging 50 lowest, 55 ave and 60 highest temps with occasional fluxuation of 65c on core1

[acwilson96]

Exactly

Just finished 45min stress test with AIDA64 and average CPU temp was 50c so I am upping the multiplier to 41 and will run around an hour again and see if stable. If stable then I will go 4.2GHz with 1.25V as I tried 1.2V 4.2GHz and it crashed.

When reading temperatures during stress tests, should I be looking at max temps or average temps?

I like looking at max temps to be on the safe side of things, anyways man you struck gold with your chip if it can run 4.2 GHz (stable) without hitting the 75 - 80 degree mark.

(4670k) Im on 4.2GHz with 1.25V and getting highest of 73c with AIDA64 but around 53c average over all cores.

cool, then you've got quite a good chip on your hands. you can probably hit 4.5 GHz and get like 80 degrees max. (4.5 GHz is any processor's sweet spot imho)

I am talking to my friend who overclocks all the time and has lots of experience and he says that I shouldnt be overclocking without LLC/vDroop and that my chip is average and 1.25V is too much?

I would call it at least above average, a lot of people can't get the 4670 to go past 4.2 GHz without the temps being out of control. 

as for LLC/vDroop, it improves stability because it prevents your CPU from reducing voltage under load, if you want to take his word that 1.25 is too much then take it, else google i5 4670k overclocking guide or something similar and see what others have to say. I know people having to go over 1.3 volts to get to 4.2 GHz even with LLC enabled. here is a so called "safe" guide on the haswell chip overclocking http://www.overclockers.com/3step-guide-to-overclock-intel-haswell

 

 

I myself also always overclock by the way.

Ok thank you, he also reccomended OCCT and due to being long time friends I took his advice and 1.24V 4.2GHz was failing like 3 mins in!

is that with LLC enabled or disabled?

[acwilson96]

LLC disabled I assume as I dont even have the option on my board. (Z87M G43) Do you recommend AIDA64 or OCCT for haswell?

Intel extreme tuning utility LLC could stand as something like load line calibration or something on your board, give me a few minutes I'll research the boards bios and get back to you.

well it seems quickscoping I can't find anything about LLC for your board aside from you asking about it on a bunch of other forums and one guy referring you to the manual which is a complete waste. (I'll try again later it is possible they didn't include LLC for some reason though)

 

Also check ProKoN's overclocking guide since it's another good reference you could use.

Sorry to say, but 4.2Ghz @ 1.25 is nothing to write home about. It's too bad you can't achieve 4.2Ghz with a lower voltage actually.

 

To give you an idea, I get 4.6Ghz @ 1.27 and get a max temp of 73 degrees running Intel Extreme Tuning Utility. There's at least one other person on here who has the same overclock as me but with a lower voltage (1.25 I think).
