Intel Core i7-4770K Overclocked to 7 GHz
Launch of Intel's Core i7-4770K "Haswell" processor may be a month away, but the chip has been in circulation for some time now. An overclocker going by the handle "rtiueuiurei" managed to get an engineering sample of the chip past the 7 GHz mark, 7012.65 MHz to be precise. A base clock of 91.07 MHz, multiplier of 77.0x, and a staggering 2.56V core voltage, unless CPU-Z read it wrong. A single 2 GB memory module was used; no other details were revealed. Core i7-4770K and a fleet of compatible socket LGA1150 motherboards launch around the first week of June.

:roll: But you cannot. Too bad. :p
One user from OC kingpin cooling who posted this info at guru3d forums said so.. I take his word for granted, becasuse he's no noob ^^
And if you look at that quad 6.2Ghz @ only 1.21v:rockout:
Anyway I can't wait to get my hands on 4770K, looks like 5.4ghz won't be a problem, probably 6.2 ghz for sure, woot! :]
Things are a bit different with Haswell, it seems, compared to SB and IB overclocking.
I wish I caught that sooner even though I already knew the vcore was bogus, now I know the entire thing is bogus.
Maybe that's why CPU-z reads 2.62v, hmmmm.
And have you ever seen some of the extreme shit these extreme overclockers do to their motherboards?
They add phases, bridge phases from other motherboard into one, etc.
Have you never seen that?
This was a suicide run, obviously, and they'll do crazy shit just to get a CPUz screenshot before the system dies.
The point is that you would need to at least replace all of the caps with ones that support twice the voltage (which could easily translate to caps that are twice in size.) Now that you've swapped out the caps you would need to hack the BIOS because the caps will burst if you even attempt to run VRMs at this voltage. Also if the capacitance of any of the different phases changes, you need more than a custom bios, you need to update it to handle the hardware changes you've made.
Also the addon board you speak of I've only seen for Kepler-based GPUs since voltage control is locked. I've yet to see this for the motherboard and CPU power phases, but once again there is a different reason for that. It would have died the second it booted with a voltage like that. LN2 doesn't let you overcome physical limitations like the breakdown voltage of the caps. You'd pop the caps (haha!) before the VRMs could even charge. :laugh:
From TechPowerUp three weeks ago:
I don't know, but if you're throwing out words like "bogus" and "now I know", wouldn't you at least spend 30 seconds making sure you were standing on solid ground ?
