Core i7-4790K Overclocked to 7003.38 MHz on ASRock Z97 OC Formula
Nick Shih has set a new overclocking record using an ASRock motherboard and an Intel CPU.
Overclocker Nick Shih has set a new world record for overclocking the Intel Core i7-4790K processor. To do this, he has used the Z97 OC Formula motherboard from ASRock.
The overclocker has brought the CPU up to a frequency of 7003.38 MHz, with two CPU cores enabled and hyper-threading disabled. The core voltage was brought up to a staggering 1.792 V, and to cool this, we can only assume that a lot of liquid nitrogen was consumed.
Of course, such overclocks are not sustainable on a day-to-day basis, but it's always nice to see how close the hardware can be pushed before reaching its breaking point, which seems to be quite high here.
So, when you buy a new motherboard, does this kind of information sway you in favor of the motherboard itself, the vendor, or does it not affect your buying decision at all?

LOL that "Hyper-Junk" would allow a stock i7-2600K to outperform yours in some games.
I wouldn't call it holding back, but it degrades the chip and shortens the life of the CPU. Not exactly a good thing..

What game(s) utilize more than 4 cores efficiently?

I would like to see a stock i7 compete against an OC i7 lol. Even with Hyper Threading disabled. I have a 2600 too @ 4.3 and I really don't see any reason to upgrade.
And this overclock to 7ghz, who cares, its not stable, you can't use it. If it were 5.5 or 6ghz and underwater and stable for daily use with low temps, I would be very excited. I like practicality and usability, those are most important IMHO.

You do know that hyper-threading actually decreases FPS in games, right? Look it up before commenting...

Guild Wars 2 is the big one here... my friend upgraded his i5 to an i7 3770k, and running that at stock speeds against my i5 2500k (4.4 Ghz), he gets about 30% more FPS than I do. Sure that shows that the game has some coding inefficiencies, but still, I just wanna play my game
In all honesty the only real reason to upgrade the CPU is for more bandwidth and PCI lanes. I’d say the best place to look at speeding stuff up is the GPU memory size/bandwidth utilization and storage. Most cards haven’t come close to touching the bandwidth that the PCI-E can provide. And storage devices are still fairly slow even the new M.2 standard is fairly slow in the grand scheme of things.
You might want to look at BF3/BF4, Watch Dogs and other higher-end game benchmarks.
HT has a SLIGHT negative impact on single-threaded games but also has a significant positive impact on more heavily threaded games and applications.
Which model of i7, and what benchmark tests are you interested in?
Ian.
Most likely not since they already need to disable HT and two cores just to get the thing to boot into Windows.
I wish OCing contests required that overclocks be Prime95-stable for 10 minutes to qualify... and have separate categories for fully-enabled CPUs and completely unrestricted crippling.
Even better, 10 mins stable using 1344 and 1792 FFTs.
with P95 but don't last 5 mins at these sizes. Good idea about the categories aswell.
Ian.
Dont comment if you dont understand the tech.
im curious if they get diminishing returns on performance as clock speed increases. At what point is it not worth it?
Yepper! I found better FPS with HT disabled and a higher clock speed than having HT enabled. Even BF4 was tested. But yet again I do have high video card bandwidth.
