Intel Core i7-7700K Cracks 7 GHz Bench-Stable Overclock

It may have practically no IPC gains over its predecessor, but Intel's 7th generation Core "Kaby Lake" unlocked processors are shaping up to be an overclocker's delight. A Core i7-7700K sample tested by professional overclocker Allen "Splave" Golibersuch was able to breach the 7 GHz barrier. To achieve this feat however, HyperThreading was disabled, and two of the four CPU cores were also disabled.

Paired with an ASRock Z170 OC Formula motherboard, the i7-7700K was bench-stable at 7022.96 MHz, at the chip's maximum base clock multiplier of 69x, and a base-clock of 101.78 MHz. The Vcore voltage was set at a scorching 2.00V. The chip crunched PiFast in 9.02 seconds, SuperPi 32M in 4 minutes 20.25 seconds, wPrime 32M in 2.953 seconds, and wPrime 1024M in 1 minute 33.171 seconds. Paired with an ASUS GeForce GTX 1080 STRIX OC graphics card, it scored 643,316 points in Aquamark, and 86,798 points in 3DMark 05.

2 of 4 cores disabled? Nope, sorry... doesn't count as a real overclock in my book.

It's only stable at 6.7 GHz in Wprime 1024M too

Are we back to Intel overclocking records to make news?

I hope AMD doesn't phenomenally fail, and go under the bulldozer.

Basically an overclocked i3 then, with no practical usage...

Full cores and HT or go away. Why not just have 1 core and claim 8GHz? :rolleyes: Even if it's just a highest clock bench, like for others, I only consider it valid if all cores and HT were used. If not, they've basically cheated their way to 7GHz...

Pretty much what everyone else said.

Its not a real over clock if you disable cores...

Lmao it's not a daily type cooling it benching big difference...

I would be happy to getting back in to ocing but it's expensive when you don't have sponsors and it's lots of fun killing stuff lol

You can definitely tell what kind of page this is. @EarthDog WTF?

This is why TPU's hwbot team is dead.

SuperPi 2M in 4 minutes 20.25 seconds
Should read 32M

1 core or 20 cores, its still a good overclocking feat.

I guess some people don't get the logistics of overclocking...

Well, I tried last year. Now all of my relatively overclockable HW is gone.
What's really sad, is that after a year of doing nothing I went from #11 on TPU team up to #8 :banghead:
Not even sure if there are any active members left...

could you validate it?
wait, what? you can run kaby lake on windows xp?

you misspelled pentium dual core,

Yep, meaningless in the practical sense. Interesting as a purely academic exercise. When are these chips released?

Why not?

So as overclocking in general. Or car tuning. Or competitive eating. Or yoga.
Fun does not have "practical applications"

Almost all benchmark runs are meaningless in the sense of general practicability. They prove a concept of speed and performance, nothing more.

As @EarthDog and @cdawall have lamented, it's not performed as an indicator of how fast the chips will run 24/7 but how fast they can run balls out.

Yes, I fully agree. The "concept of speed and performance," as you nicely put it are still interesting, but yes, of course, not for regular 24/7 usage.

Oh, I didn't mean to sound like a wet blanket. It's definitely fun, and I am very glad people do it.

EDIT: Thanks for the hwbot link. Interesting

I must say I would be impressed even if it was one core. To see a piece of silicon of that complexity hitting clocks in the 7GHz realm is quite something...

Overclocked quantum bit
Only two cores working to achieve this? Ok fine. Well, why not simply disable all cores and see how high the clock circuit will go? I'm sure we could hit 10GHz or more with that. /sarcasm

Heh, that's a great idea. I reckon at least 10GHz, probably more. /sarcasm

This a "kind of but not really" record. Disabling HT and turning off 2 cores means its not a 7700k anymore in my opinion.

Not even an i3 because those have HT iirc.
