World Record: Haswell CPU Overclocked to 7193.8 MHz

Do you enjoy overclocking? It's fun if you do it right. One overclocker, Chi-Kui Lam, is probably having quite a lot of fun, as he just set a new world record for the Intel Core i7-4770K. Chi-Kui managed to overclock the chip to a very respectable 7193.8 MHz, which is the highest frequency recorded for any Haswell product to date.

Of course, there are certain costs to reaching such a high frequency. These include using liquid nitrogen for cooling as well as a staggering core voltage of 2.048 V. The CPU's Hyperthreading also had to be disabled, along with two of its cores.

Other hardware used included an Asus Maximus VII Gene motherboard, 256 GB OCZ Vertex SSD, Corsair Dominator memory and a High Current Pro 1300 W power supply from Antec. An Nvidia GT 630 took the graphics load off the iGPU.

Of course, there is no question that this is a completely useless exercise for everyday purposes, but it remains fun to see what certain hardware combinations are capable of.

    No not a Pentium D, a Pentium G3258 20th Anniversary Edition.

    So... This isn't actually a world record, it's just a record for a Haswell? Because those are some seriously different things, and I'm certain that a bunch of AMD chips have been taken past 8GHz, and that was a couple of years ago.

    It doesn't stop this being cool and all, just that if you're going to call something a world record, it really needs to be the world record for all comparable things. It's like saying that a station wagon set a world speed record, then finding out that it was only for station wagons.

    Are you sure? As I understand it, the Pentium D was a true dual core Pentium 4 with hyper threading disabled and the P4 was architecturally quite different from the prior Pentium 3. IIRC Intel scrapped the P4 and went back to the design philosophy of the Pentium 3 when they designed the Core Duo CPUs and their successors.
