I'm not as up to date with stuff as i use to be, but if the Haswell chips are like the previous generation chips, you can easily overclock up to 4Ghz by changing the TurboBoost multiplier. Or you can set the primary multiplier to 40x and allow the board to chose the voltage dynamically since you don't want to play around with it, just run some tests to make sure it's not automatically giving it too much Voltage or getting too hot.
But I make it will afect CPUs lifetime? If I set to 4GHz (100 x 40) and set vcore auto, it will drastically make it working less?

Sorry, i quickly edited my last comment just before you quoted it tongue.gif

No, overclocking to 4Ghz won't dramatically affect the CPU's lifespan. Just make sure the VCore isn't too high and it's getting adequate cooling. I'm guessing you won't be keeping it for 10 years anyway.

I want to keep it at least for 5 years or 6. The auto vcore for 4GHz that MB chooses normally is high or low? For example running witrh 1.3 vcore for years, it works for 5 years?

You need to see if your board has the auto VCore features and how high it decides to set your CPU to. If it looks too high you can try dropping increments of 0.05v until no longer stable to determine the lowest VCore you can run the chip at stable.

It's very hard to predict a CPU's lifespan once overclocked, but it shouldn't need to run very hotter or at much higher voltage to OC from 3.5Ghz to 4Ghz and auto voltage for a small overclock like that should be fine. If you were to go higher i would suggest playing around with the settings yourself and adjusting Vcore, LLC, etc.. You could get better results and a higher overclock this way.

All you have to do is this:

 

  1. Overclock it to 4.0 GHz using an Auto core voltage
  2. Watch the core voltage in CPU-Z while running Prime95's Blend test
  3. Check with the experts on Overclock to see if that voltage is safe for 5 years

I want to know if 1.2 or 1.3 are safe values or if it's dangerous. I don't pretend to change vcore values, but want to know about it, because knowledge is all.

i dont know how it is for haswell, but for Ivy/Sandy the rule of thumb was not to go near 1.5v unless you had fantastic cooling. At least that's what i was told.

Or you can ask now. You can even make a new thread. Ask something like,  if you were to overclock to 4.0 GHz with an Auto core voltage, then what voltages would be too high.

Well, if with @4,0GHz and auto vcore the temperatures are good, the system is stable and it reaches 1.3v max. it'll crashes? I won't change vcore, just perhaps 1 or 2 years later try to OC to 4,0GHz, but perhaps. Just want to know if it's safe.

Read the reviews for them in Newegg and Amazon.. just by a sheer amount of reviews whichever has IDK 50+ or 100+ 4 Star plus reviews should be good.. and that is without even reading a page of their reviewers' opnion.
