Overclocking i7-2600k

[adonzil1492]

Hey guys,

I am currently OCing my i7-2600k. Its running at 4.3GHz now, (43x Multi and 1.3v). Its pretty stable.

My concern is the temperature. Under load (when turbo kicks in) I get up to 71 degrees. I'm using prime95 and just looking at the temp straight off the mobo.

Although I dont think this is terribly bad for the CPU, shouldnt I be able to get more speed without already getting into the 70s? Or is 70s actually a bad temp?

Heres my rig:
Corsair 800D
EVGA FTW Z68
Intel i7-2600k
16 GB Corsair Dominator RAM
Cooler Master 212+ Evo
Corsair Enthusiast AX850 PSU


Let me know if you need any other information. Also, I'm relatively new at OCing, this is only my second one. If you see anything wrong or out of place with my build or my OC please feel free to criticize me.

Thanks!

70 is alright, but could be lowered., however the 800D was initially optimised for water cooling. What thermal paste and how did u apply it? Make sure your 212 has proper contact with the CPU.

First, thank you for the response I really appreciate it.

I'm planning to have this case for a LONG time. And don't have the time to do my first water-cooling now.

I used Artic Silver Thermal Paste, but I did feel that I may have messed up the 212. I get about 27-30 degrees in normal usage, it just jumps alot when I run any stress test. (This is obvious, but it jumps more than I expect, from 27-30 to 70s)

Im just gonna reseat the cooler, thanks for the help.

Thanks

Kind of high for a 4.3ghz, anyways did you follow the guide? http://www.tomshardware.com/forum/274821-29-sandy-bridge-series-overclocking-cores-guide
Did you apply AS5 the correct way? Also, AS5 takes a week to burn in and actually start cooling properly.

That massive instant jump is normal. as you are looking at internal DIE temp of your core's.

I will idle at 30-35 and it will instantly jump to 50-60 as soon as i start something like P95. but will stay at that temp

I have 2x 240 RAD's and a watercooled MOBO also.

What voltage are you using @ 4.3ghz

 

[tomskent]

1.3v is too much for only 4.3ghz.
I think you will have no problems with a lower voltage.
lower voltage = lower temps
...and yes, make sure your heatsink is put on their correctly, that will make a big difference.

 

[tomskent]

AS5's does take some time to work at its best, but the difference between when you first apply to when its fully done is between 1-3 degrees, its not a lot.

 

[HugoStiglitz]

sorry didnt see voltage in OP.

but yes 1.3 is a tad high for 4.3ghz.

im using 1.275 for 4.5ghz.
