Overclocking i7-2600k

post #1 of 10
Thread Starter 
Hey guys, I'm looking into overclocking my 2600k. Before I did that, I decided to run prime95 and see what kind of temperatures I would see with a stock 2600k. I got the following:

To me, these temperatures seem a little high. I am cooling my CPU with a Zalman 9700. My highest core idles around 34 C.

Is that high of a temp normal with a stock 2600k? I would like to just try and get to 4GHz. Do you suggest I get a better heatsink? Any insight is greatly appreciated.

Also....I have an ASRock p67 E4 G3.

Yeah , the temps seem a bit high , i would get a Thermalright Silver Arrow
here are some temps (yeah it's the noctua NH-D14 but they are similar in performance and the Silver Arrow is quieter)

Okay, I will probably end up getting a new Heatsink. When I OC do I want to have the Core Voltage on fixed or auto? Seems like if it was auto it wouldn't be running hot all the time.

Okay I ended up clocking it to 4GHz. One Thing I am noticing is that when I am running prime95 the multiplier is jumping around from 37 to 40, but the load is at 100%. Seems to me it should be at 40 when I am running 100% load.

No, I had not. I ended up just over clocking it to 3.8 @ 1.175V. I ran prime95 for about 20 minutes just fine (max temp 67 C). I played counter strike for about 2 hours and was browsing the internet right after and all of a sudden my computer froze and s scratching sound (kind of like the sound an old printer makes) started playing through my headphones. I didn't get the BSOD, my computer just froze up. I just turned my system off and reloaded the defaults. Any idea why it did this? My temps were at around 42 when I crashed.

I wouldn't ever leave the voltage on auto when overclocking. I've got the gen3 extreme3 board, when I messed around and put it to 4ghz with auto voltage, it was feeding the CPU 1.44V! Way too high. Also I had to change the turbo duration settings so the multiplier wouldn't fluctuate. I think I'm running 4.2ghz with a little under 1.3v right now.

Okay, is that all you changed? I have read all different kinds of overclocking guide and they all say to do a different thing. All I want to do is OC it to 4.0 and be done with it, I don't want to OC my Ram. Is it as simple as changing the multiplier and voltage?

If all you want is to get to 4ghz then you won't even need to touch the volts. I have the same cpu running @ 4.8 ghz @ 1.4v and sometimes @ 5ghz at 1.425v and got no problems. In your case (and i have tested this) all you have to do is go to the bios and set the 'Ai overclock tuner' to xmp, and set the turbo ratio to 'by all cores', then increase it to 40- hit f10 then enter and you should be fine @ that. I did the same thing with my p8z68-v pro/gen3 and it worked perfectly fine.
If you notice your volts going over 1.220 @ this point then i would definately suggest that you go to the bios and set the volts manually as your bios would be the culprit at this point.
I will also mention that it is a great idea to first check and see if your motherbaod has a bios update and if it does, get it and install it. When i just got the mb and install the cpu i saw high temps and high volts. I went and check and found that there was indeed a new bios. I install it and sure enough my volts & temp all went down.
To give you an idea of my temps, my room temp is current 74'f and my cpu is @ 4.8ghz @1.4v and the temps on my custom killoliquid setup is 26'c idle/ 36'c light load/ 41'c heavy load. Hope this helps.
