Temps are more important than voltages. Making sure that your cpu, motherboard nb,sb and vrms are kept cool

Overcloking is about the passion, not about how much you clock
Overclocking is not about the pefromance gains, it is about the passion
Overclocking is about the Fun, Enjoyment and Passion

Pushing Voltages And Lower Tempertures Makes You The Overclocking Champion

Actually, voltage is far more important than temperature. You can degrade a CPU within minutes with high enough voltage even if you're using LN2.

For ivy bridge, you want to keep it bellow 1.35V. 1.38V should be the cut off, with anything over 1.4V bringing degradation in a few months depending on usage.

You should be able to run 4.6 safely. I dont know about 4.7 though which will probably require close to 1.4+.

Just keep in under 1.4 volts and don't stress test with something like Intel Burn Test.

Use Asus Real Bench for 2 hours and you should be set if it passes.

I learned the hard way with IBT. It will definitely shorten the life of your CPU at higher voltages.

i have been stress testing with Prime95 blend tests , i have reached 1.38V but prime95 shuts down which is a sign of in stability frown.gif

With Ivy I wouldn't go above 1.35 vcore under load, Haswell 1.3v with sandy and the new skylake stay at or below 1.4v under load.

When I was researching the 3770k overclocking it seems they said less than 1.3v for 24/7

Been running my 3570k at 1.328 ish volts under max load most of the time since 2012. Even Folded on the CPU for a year or so, as well as a fair amount of gaming.

Id be happy with around 1.35v if temps are in check. Some people have even push closer to 1.4 24/7, but that depends on how easy it is for you to replace it if it or the motherboard does pop.

4.6 at 1.31 is good, if you cant get 4.7 for 1.35ish Id just stick with that, its not a difference you would notice IMO.

In the future everyone will be Ozymandias for 15 minutes. Or something.

Unrelated to other Slinkies.
