Hello,

Today i did my first overclock, want to see what you guys(or girls) think.


Computer specs.

Intel i5-3570k
Asus p8-z77 motherboard
Noctua dh14 heat sink
G.skill DDR3 PC3-12800 1600MHz Ripjaw Series ram


I ran Intel burn test on very high and got a max temp of 90c averaged 75-85c.

Then i ran prime 95 for about about an hour and got these results.

end result is 4.5Ghz at 1.288 V (jumps to 1.320 V under load).

let me know what you guys think of my first overclock.

Also here is the tutorial i used.

:) ) Hey There Very Nice that looks Good man Keep in Mind Ivy Bridge throttles at 105 C. If you want to play conservative and be safe, I'd advise keeping it under 90c!! You can Prob go Higher to 4.6ghz if you're lucky watch those temps keep it under 90c :) ) But good Overclock!!

I'm at 4.8ghz with Voltage of 1.42v & Max Temps I got is 88c :) ) that awesome your temps is like that with Prime95 you can prob hit 4.7ghz with your System ;)

you seems to have bad airflow in your case, i personnally get a max of 85Celsius with a Noctua NHU12P SE2 (one tower of the NH-D14 and 120mm fans 3770k 4.83ghz @ 1.35V)

Higher ratio need more voltage (on mine) 4.83ghz @ 46 ratio and 105 base clock need only 1.35V and 4.8ghz (48X100) need 1.425V... BTW, great overclock ^^ and those temps are safe, you don't need to bother about them...

Your temps are completely fine man. That's a good overclock. At 4.5Ghz on my 3570k I use 1.300 volts. So your voltage is right around where it should be. And I get about the same temps as you also. Maybe a bit lower. I get a max of about 84C while using Intel Burn In Test at 4.5Ghz. But we have different coolers, different cases, different thermal compound, and different motherboards. And that does make a difference in temps a little. Although your CPU cooler should be a bit better than mine. But all chips are different so I think your fine.

Personally I would go up to 4.7Ghz cause it seems your chip takes about the same voltage as mine. I can get to 4.7Ghz using 1.385 Vcore. But my temps are about 92.5C average while using IBT. So my temps are a little over what I'd like but during normal use I'll never get my CPU nearly that high. And in prime95 my temps are only 82C average. Theres really no need to go any higher besides that you can. So yeah good overclock.

4.6 here at 1.28 volts

I agree with spawnkiller. You might wanna check your air flow and maybe test some negative offset voltages. I set my i7-2600k at 4.5GHz with a - 0.070 negative offset and my temps are around mid 70's Celsius under stress testing and high 30's under light loads. At any rate, you're off to a good start. :bounce:

Sorry for the late ass reply, apparently email notifications are not working.

I'm running with the Cooler master HAF 932 so airflow is not a problem, i just live in a hot climate.

I have also tweaked some more and got temps down a few degrees.

:hello: 


My cpu doesn't like negative offset, always get BSOD.

I tweaked some more and dropped a few degrees, but i live in a hot climate (about 85f in house) so i don't expect to get to lowest temps possible.
