Overclocker Pushes An Intel Haswell Core i7-4770K CPU Beyond 7GHz

OCaholic has spotted an interesting entry in the CPU-Z database. According to the site, an overclocker by the handle of “rtiueuiurei” has allegedly managed to push an engineering sample of Intel’s upcoming Haswell Core i7-4770K processor past 7GHz.

If the CPU-Z entry is accurate, the overclocker used a BCLK speed of 91.01 and a multiplier of 77 to achieve a CPU clockspeed of 7012.65MHz. The chip was overclocked on a Z87 motherboard along with a single 2GB G.Skill DDR3 RAM module. Even more surprising than the 7GHz clockspeed is the voltage that the overclocker used to get there: an astounding 2.56V according to CPU-Z.

From the information Intel provided at IDF Beijing, the new 22nm Haswell processors feature an integrated voltage regulator (IVR), and the CPU portion of the chip’s voltage is controlled by the Vccin value. Intel recommends a range of 1.8V to 2.3V for this value, with a maximum of 3V and a default of 1.8V. Therefore, the CPU-Z-reported number may actually be correct. On the other hand, it may also just be a bug in the software due to the unreleased-nature of the Haswell chip.

Voltage questions aside, the frequency alone makes for an impressive overclock, and it seems that the upcoming chips will have decent overclocking potential!

Pretty nice overclocking even more so considering they have all 4 cores enabled where as mostly any other extreme overclocking is 1 core(2 for AMD since module's don't allow it to)

LOL what a load of crap, that's definately fake

you have any proof its fake? if this is fake could call any the AMD ones fake as well.

So how'd they do it? Stick the mother board in liquid helium?

Yep...something like this: https://www.youtube.com/watch?v=63qPiG1AkKE

Most likely! :)

It could also be an unstable overclock, when AMD did their world record overclocks, they were able to run 3Dmark11 and get a score, so this could have been done using a second computer, or just not put it under any load making it much easier to do. That means when AMD did it they had it at 8.67 ghz, they did it while running 3Dmark11. Although it is impressive, it's not that special, show me a video of it running some sort of stress test and then I will be impressed.

also in that video it went to 6.5ghz for about half a second.

how many cpu cores were enabled on that amd Overclock? 2? since that is few cores you can have enabled on an amd now, this has 4 enabled so its much harder to get up high numbers.

DANG! thats impressive. i wonder what he did to get that high of an overclock.
Also anyone know if there is a video of AMD over clocking the CPU for the world record?

Even if that clock speed screen capture was legit, WHO CARES?

That's not a STABLE sustainable speed. Any idiot can run their car engine at max RPM and burn out your engine, show me a fast and stable clock.

Now that would impress me.
