Intel's Core i7-4770K Overclocked to 5.0 GHz on Just 0.904 V

It appears that someone has managed to overclock the i7-4770K to a whopping 5.0 GHz using just a measly 0.904 V.

So far, we've seen the i7-4770K overclocked to both 7.0 GHz and 8.0 GHz, and now we see another overclocking something that's possibly even more impressive. While the overclock shown here might just be one that goes up to 5.0 GHz, it appears that the overclocker has managed to pull this off at just 0.904 V.

Now, what is clear from the CPU-Z screenshot is that the overclock has been pulled off with HyperThreading disabled.

In the meantime, another overclock was shown as well; one where the chip ran at 3.8 GHz at a mere 0.719 V.

Of course, while these overclocks are impressive, it remains to be seen whether they are actually stable. It is very possible that once a load is applied, the CPU destabilizes and the system crashes.

    the computer would have to go under load when loading up windows, even if it is for a short while... i wonder HOW stable it is... if this is true, and the person got it to 5.0ghz, an upgrade from ivy bridge may actually seem worth it!

    I am able to post my core 2 quad with a 60% overclock but it's worthless. @ 1.47580V
    just sayin.
    Haswell should scale down nicely!
    1 netbook with a 2Ghz 1 core while hyperthreaded please, @ 0.5 V please

    That is impressive. So if .9v at 5ghz is fully stable(lets assume) how much higher can it go with more voltage is the question.

    I really want to see the temperatures of these things.

    They mentioned a limit of or around 8Ghz because of the multiplier limitations.

    Interesting, well I just hope this is true, this chip can have a lot of overclocking potential.

    This is a major win for mobile.

    They mentioned an limit of or around 8Ghz because of the multiplier limitations. - Try about 5.5 GHZ Limit. And that may not even be totaly stable in all applications.

    just a stupid calculation:-
    1.maximum recommended volt/this one 1.5/0.9 = 1.66666666
    2.1.666666 * 5=8
    it looks like 8Ghz is really the max clock for this epic CPU

  • Question is, is it worth an upgrade for us that are still on Sandy Bridge (2600k) from 2 years ago I want to see that comparison.
