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.

Then again it depends on the cpu lottery some chip could take more or less vcore but overclocking without vrm heatsink is asking for trouble you can kiss the motherboard on that. With the 9700k series cpu you could nearly add 150% power comsumtion over the standard stock speed as jay2cent mentioned that on youtube as one of the intel chip was just 400watt in full tilt with cinebench then overclocked it was somethinking like 560 to 580watt in cinebench you would need something like 1500 to 2000 watt power supply to keep all the computer parts happy

XzibitMaybe 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.
Not only that, there is only a 4 pin in the 8 pin socket... something is definetly wrong with that setup unless it was “just for the pics”

1000W is more than enough even for this kind of overclock. Even 850W, unless you go amd vega, which by the way eats up the same amount of power as amd fury did, but I hear no mention of that...
techy1so 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)
Frequency improvements over time due to continuous refinements of the 14nm manufacturing process (lesser errors, allowing all transistors to hit a higher stable frequency), as well as soldered IHS which does help.

The cooler used is this one, or am i wrong?

JalleRWhere is the Sleasy NVidia preorder tactics..... I want to PRE order NOW...… :) If its true it is a really Flimsy cooler for that OC.
As long as folks remain to be primarily driven by "impressing their friends" and getting attention with their new phones, new sneakers. LEDs, "faux" water cooling, and being the 1st on on the block to have the new shiny bauble, pre-order will remain an embarassment to us all. And then there's the other side who want to prove they 'are not sheep" by buying the 2nd most popular thing ... even is it's numbers are worse, damn it, they gonna show everyone they not a follower :).

And as long as that market exists, no company woiuld be foolish enough to ignore them.
StrayKATI guess all the complaints about soldering actually is proven right (I never really doubted it, but I didn't exactly care either).
Actually, since Sandy Bridge (4.8 GHz), I never had an OC determined by temps ... always hit the voltage wall (1.4 in BIOS / 1.5 observed) before heat was an issue. But I skipped Ivy Bridge ... that was the only series where I thought delidding was warranted.

meh, i'm more concerned with the i9.

Yeah, have same problem of failing to find cooler mounting.
But then again it's Intel and hence must be capable to working on by holy spirit...:p
dangrigI like how tech leaks and aliens are always recorded with the most potato camera possible. :D
Maybe that PC crashed before they could actually take and save screen capture?
I mean it's such demanding operation that you can't expect overclocked PC to survive stress of it...

1.215 volts reported in CPU-Z isnt exactly accurate/ or even fool proof! yes it may be reporting 1.215Volts,

*** but is that really the case, as Gamers Nexus has shown before, using a multi-Meter and actually checking / testing the voltage at the CPU socket on the Pin for supplying all the voltage to the CPU could actually be Lower!!! ....
or much much higher than actually being reported !!!!! Not only in the BIOS, But also almost any system monitoring program or application ?? also depends on the LLC, AKA ( Load-Line Calibration ) settings!!!

the actual voltage in CPU-Z ( as reported @ 1.215 V) could actually be 1.025 V or even 1.425V wich could possibly be way too high for a particular CPU and it may run for a long time, it may only run a few hours, or it may even just fail on immediately

or internal cpu components could fail over time, like the iGPU, or Memory controllers, the CPU NB ( aka Chipset in CPU - also known as the memory controller as well)

im 34 yrs old now ! and have been in PC building for the hardware/gaming PC's scence i was 8 yrs old ( THANKS ADD / ADHD -LOL- ) so iv been building / upgrading and repairing and even overclocking for a couple decades.. 2 decades, a minimum of 20 yrs. , ...
26/27+ yrs total i believe, so 30 would be 3 decades_ but 3-4 more yrs and almost 3 decades of working with computers/ mostly hardware interest

all the way back scence 1992/93 back in the 3x86 - 4x86 and pentium processor days, even the OLD Intel Pentium Overdrive CPUS, any one even remember those lol, damn i miss those old days..
