Intel Core i7-9700K All-core Overclocked to 5.30 GHz On Air

Intel's upcoming 8-core/8-thread Core i7-9700K is in the news yet again, this time with a noteworthy overclocking feat of 5.30 GHz with all cores enabled, under air cooling. An enthusiast with access to an i7-9700K chip and an unknown motherboard posted blurrycam pictures of their setup and a CPU-Z screenshot showing 8-core/8-thread config, and 12 MB L3 cache, confirming this is an i7-9700K. The multiplier of this chip is dialed up to 53.0x, which multiplying the untouched base-clock works out to ~5.30 GHz. The core voltage made it to the screenshot - 1.215V.

The most impressive part about this feat is the cooling. A mainstream-looking tower-type cooler is used. Crossing 5.20 GHz with all cores enabled takes current-generation i7-8700K at least AIO liquid coolers. This is probably a testament to the soldered IHS the i7-9700K is equipped with, which improves heat transfer between the die and the IHS. Then again, it could also be the effect of a lack of HyperThreading. At higher overclocked speeds, disabling HTT on current-generation Core i7 processors contributes to stability.

I guess all the complaints about soldering actually is proven right (I never really doubted it, but I didn't exactly care either).

Maybe i'm not seeing it but how is the CPU cooler mounted? Looks like its just laying on top of the CPU. MB mounting hole is there empty.

so prev gen could push 5.1 max 5.2 (both delided), now this can go 5.3, so same IPC, same old hardware buggs, and +0.1 freq... *sign me up and charge me 350$ for non HT true cpu next gen*
* - (Ture = False)

Anyone can do as much as we know about this (booted at 5.3GHz and took a picture of CPU-Z), even with a not-so-great air cooler and monkey spit paste HEDT chip. Is it actually stable? What are load temps?

1) its not in a case cooling
2) the picture is not clear and cant see what cooler it actually is
3) what is the ambient temp?
4) 5.28 is not 5.3

This is as bad as using a chiller to claim top prize. :shadedshu:

A few things about this:

CFL is CFL - expect the same voltage to frequency ratios.
This is nothing but a post in a frequency, can be done in a much much lower voltage than needed for any kind of stability test

Apparently its using this cooler

DeepCool GamMaxx 400




If you look up the install instruction and look at this pic



Something is odd

maybe they cropped it to hide the chiller? o_O:rolleyes:

I remember my old Nokia 6600 with VGA camera to have better image quality than these pics.

Well, the multiplier is 53x and it's not that uncommon that the BCLK isn't stable 100MHz at least all the time. My i7-5820K seems to be around 100.2 even I've set it at 100 in bios.

So by association we are being led to believe the set up in the second pic is the same as the first CPU-z shot?
Why is the cooling missing from the VRM section, if they used an ordinary tower cooler?
Something is amiss.

That cooler doesn't have these closed sections on the sides.

Not bad...if it's true...too bad it does not work on Z270 :) , anyway I am waiting for the 7nm Zen2

Tech Journalism is dead.
Not really. Before launches these things have always flourished.

Where is the Sleasy NVidia preorder tactics..... I want to PRE order NOW...… :) If its true it is a really Flimsy cooler for that OC.

thats fine but bragging rights means OVER not under.

This could probably be achieved with an 8700k. Just go into IET, crank everything up, hit apply, take a picture of your frozen computer screen.

Yeah it'll boot on 1.2v no problem, even at 5.3

There is just no way these chips will do 1.215 at full load with 8 cores at > 5 Ghz. Just. Not. Happening.

That hole is from VRM heatsink, the CPU cooler mounting screw you can see it a little more to the right.

1.215 volts, lmao thats a 5.4ghz chip on water i bet

1.215 volts at 5.4 gig sounds a little to good to be true.. :)

Nope, the hole to the left is the CPU heatsink mounting hole, the one you point to is the screw in the middle of the bottom of the socket retention mechanism.





It looks to me like the heatsink might only be held down by two screws with an S bracket running between the top left and bottom right screws. It's a lazy way to do it, but probably good enough to keep the heatsink held down on a horizontal board.
