Intel's Core i7-4770K Overclocked to 8.0 GHz; See Video!

By - Source: YouTube | B 23 comments

It appears that someone might have managed to overclock Intel's soon to be released i7-4770K to a staggering 8.0 GHz.

Earlier, we showed you a screenshot of Intel's Haswell Core i7-4770K overclocked to a massive 7.0 GHz, but now we have a piece of video showing the CPU overclocked all the way to 8.0 GHz. Theoretically, the CPU shouldn't be able to go above 8 GHz due to restrictions with the multiplier and base clock, even on the "*K" version.

The video shows the CPU with only two cores enabled and HyperThreading disabled. The voltage of the CPU reaches 2.259 V as the CPU's clock speed is gradually increased.

Sadly, it shows nothing about temperatures, and for all we know, this video might well be a crafted fake, nothing but numerous edited screenshots in a slideshow, filmed to trick us into thinking otherwise. We cannot be certain, but the video below is still impressive.

    look on the bright side, they are limited to 8GHz by Intel, so this is the last of these articles we will ever have to see

    This will be my next upgrade from a 2600k, just hoping for a good OC of about 4.5 4.8 with it and about a 25% boost with cooler temps.

    so its a video of a screenshot that could be easily faked.

    Audio sounder like an old school coffee purkulator.

    We don't need the 8Ghz, 4 is good and more than enough for most of us.

    That's nice but not even the space shuttle sound effects will make this as exciting as overclocking my old Celeron 300 up to 450 mhz..

    The 8350 hit 9 Ghz with less voltage. Granted more exposure with the 4770K may yield better results but still I'm not impressed yet.

    If it is real, it would need to have some pretty hardcore cooling.

    The fact that the video's description says 3770K and the video clearly shows, or at least is supposed to show, a 4770K makes me think that its definitely a fake. If it was legit you would think the person would make sure to have 4770K in the description.

    The person who faked this didn't do their homework very well.
    2 cores, 2 threads? i7 4770k is 4 cores, 8 threads; or if you disable hyperthreading its 4 threads.

    The reason it's fake is because you can't change the speed while it's running

    Many motherboards actually do allow on-the-fly FSB/BCLK frequency change using a Windows-based UI: on my P4P800-M, this was the only method to overclock it since the BIOS did not have any overclocking option; just had to find software that could access the Winbond clock generator over the SMBus to edit PLL register values. My old laptop used an Nvidia chipset and I could use NVTune to change the CPU's FSB clock from Windows too. Many motherboard manufacturers provide tuning software for Windows that do the same thing for many of their models.

    Not sure if the Ks allow messing with the max multiplier between boots but SpeedStep definitely knocks the core multiplier up/down depending on load so the CPU is certainly capable of handling practically on-the-fly multiplier changes.

    For memory and other multipliers though, I do not remember ever seeing an option to change those outside of BIOS.

    even at 8ghz, id be willing to bet that an 8870 is still faster

    Holy shit you figured out how to embed a video! Good job!
    Next you'll be spoiling us with edit buttons.

    Does look like fake. If you got 8 GHZ you would probably Brag about it and show off.

    Considering how Haswell has ~10X lower idle power than Ivy Bridge, I would not be too surprised if that enabled Haswell to remain at much lower core temperatures during such idle overclocking and enable some ridiculous idle overclocks... but then you are only proving that the chip can do no useful amount of work at ridiculously high clock rates, which is pointless.

    Assuming those overclocks are legit, I bet they would instantaneously crash under load.

    To me, a genuine overclock record should require passing a burn-in test with all chip features enabled. None of that core/thread/cache/etc. disabling silliness. An overclock is pointless if you cannot make it do any meaningful amount of work or the overclocked chip is so heavily crippled that it under-performs its fully-enabled stock-clocked state.

    and then the CPU died, Who really cares about that extreme crap anyways, I like to see maybe Crysis 3 or something running at 8Ghz for an hour, These benchmarks are pointless
