Safe Maximum Vcore For i7 -2600K (Again,Again...)

On forums nearly everbody talk about 1.400 ~ 1.520 and upper values for Vcore of i7 2600k for 24/7 daily usage will degrade the lifespan of cpu.(assume that temps are good).

I talked with Intel's Technical Support Engineer on the live chat support about this topic and he said that below the 1.520 Vcore is absolutely safe and will not degrade the lifespan of i7 -2600k.

I want to use mine with ~1.450 - ~1.480 Vcore for 24/7. If i degrade my cpu's lifespan or even if i damage it (assume temps are all fine), it should be in terms of warrent and i can rma it.

After these chat wit Intel's Technical support would you suggest using this cpu with ~1.480 Vcore ?

  1. No it's too high. And no you wull not be able to rma it as far as I know. Now is there a certain clock speed you want it running at? And the point behind it ? Also you should pay attention to your temps. What cooler do you have?
  2. Those are too high voltages. Also, Intel will not take back a CPU that has been OC'ed. So, if you kill the CPU, they aren't gonna take it back.

    Run 1.42v MAXIMUM if your temps are good. That means with a high end water cooler as air cooling will not do it. I would stay 1.4 or under. 1.4v would make me kinda scared.
  3. ive been told anything 1.3 and under is in the green and 1.4 or higher is really pushing it

    1.3v IS VERY GOOD! But, there really isn't an issue going over it if you have good cooler. e.g. Noctua NH D-14 style air cooling or Corsair H50-70 for going up to 1.4v. After 1.4v, I wouldn't go furhter unless I had an H80 or a open-looped water cooler.
  5. just saying what ive heard lol :)

    According to the test guys here at Tom's Hardware Sandy Bridge chips start degrading due to electromigration once you start closing in on 1.4v. They have seen some chips start to degrade at a bit less than that as well. For a chip to last and be stable I would keep it under 1.36v unless you have a custom watercooling setup. Once you go over 1.4v chip life can be reduced to a matter of months.

    Also unless you have a 3 x GTX580 setup you will see very little gain from overclocking past 4.5Ghz. Some encoding type programs may scale a bit faster at higher speeds but not enough to risk your chip.

    Intel offers a special overclockers insurance for K series chips. If you really want to kill one then for $20 for a 2500K and $25 for a 2600K you can get one no questions asked replacement if you kill it overclocking it.
  7. i heard about that and when i get my gaming pc i will be buying that,id rather be safe then sorry on my first overclock. hoping my bios is gonna be nice and easy and just have a multiplier lol
  8. hm thanks for the post anort3 .. I'll look into that.
    I only succeed ocing to 4.8 Ghz while staying under 1.36v
  9. Buy the $25 (for I5-2500k, thin a little higher for I7) insurrance - no questions asked on a one time failure do to OCing.


    Don't for get even if you do not OC and use Ram at over 1.575 V and have a failure it is not covered under warrantee.
