[VIDEO] HKEPC Shows Haswell Core i7 4770K at 6.4GHz with 1.445V

Featured Replies

O lot of theory being posted lately :rolleyes: The most important factor is being ruled out (for the sake of sensationalism): good, highest bin sample.

Does it also mean that with 1.45V the CPU will bench at, say, 6.2-6.3GHz or this 'theory' is only good for 0.1s suicide screens?

why does it look like fraud? john Lam made this video i think and i don't think he'd make a fraud, but as you see just for a split second it works.

We have binned a 3770K that easily does 6 GHz benchstable and maybe a bit more with 1.4 volts under cold. But guess what ... it does not scale with voltage, so 6.2 GHz is about the maximum the cpu can do with 4 cores. And that was one piece out of 55 cpus we tested.

John Lam video_reliable?

i know the guy a little bit, he is either showing a vulnerability or something legit.

 

That really narrows things down.

Correct !! Only works for 1~3 Sec , not benchable voltage , that's why I need to need "LN2" switch.

 

For the 3770K chip which can reach 6.92GHz @ 1.488v , it is a 7.18GHz Benchable Chip @ 1.908v and max freq is 7.219GHz .

Just for the record, I will repeat myself. One, if you post something in public I will assume it's to be viewed by everyone and it's okay to relay the news. Two, if you happen to see something you wish to have removed from the site all you need to do is send me a private message or email.

 

Thanks.

 

(ps: if you still feel it is necessary to fulminate in public, that is your choice)

Saws nothing to me screan for 1 sec?

Other thinks are important as cold scaling cold bug etc. That video does not improove anything so its usless for me.

googles "fulminate"

Wiki definition looks good to me Dino :D (Or Mad just feedin Andre's ...)

 

*popcorn alert*

Understand the theory but what's the point if full pot, 1.9v gets you the highest valid speed and benching speed?

HKEPC @ GA-Z87X-OC @ i7-4770K @ DDR3-3850 Bootup:

 

//EDIT: I was asked over email to remove the link to this video due to NDA. (always nice to just have someone contact you instead of reading angry stuff on Facebook)

 

Huh,

it's already on ocaholic.ch.

Oops, sorry Stasio.

 

To clarify, that I in the previous post is me. I got an email with the request to remove the video due to nda. It doesnt matter if it is posted on other sites; i dont have admin rights there
