In the event the exhibition Computex 2014 in Taipei, Taiwan, Intel introduced a new processor model called Core i7-4790K. Chip code-named “Devil’s Canyon” was specifically designed for overclocking enthusiasts.

Now, to prove the toughness of the Core i7-4790K, Intel held a contest put on overclocking the processor on Tuesday (03/06/2014) night at a shopping center in the city of Taipei.
Overclocking itself is a technique to improve the performance boost processor frequency as high as possible while still maintaining stability. The processor in question should be able to run the application as normal despite being forced to work beyond the normal limits. This activity is a hobby for computer enthusiasts who are fond of the person who tinkers.
One of the biggest challenges is keeping the temperature in overclocking the processor from getting too hot and make the experience a computer crash or error.

In a race that was held Intel, as many as 20 participants using a wide variety of processor cooling, ranging from the fairly “reasonable” as alias aircooling alloy heatsink and fan, to extreme methods like wearing liquid nitrogen.
"Of the 20 people, eight of whom are amateur overclockers who were randomly selected through HWBOT site is the reference in the world of overclocking. Remainder is a professional overclockers are often involved in the competition" said Product Marketing Engineer Intel Darrin Lynch when met on the sidelines KompasTekno race event.
the participants come from different countries all over like Taiwan, Russia and Greece. Two representatives of the Indonesian segment helped enliven amateur overclockers. One of them had won the title three categories.
Liquid nitrogen and a bottle of beer

KompasTekno observations in the arena of competition, most participants seemed to rely on liquid nitrogen as a coolant. “The shape of the liquid from the gas does have a very cold temperatures, up to -200 degrees Celsius until the processor can reduce hot as any,” said Lynch.
The problem is, not like plain water, liquid nitrogen can not be piped to the surface of the processor because it will continuously raises condensation and frost which can make electronic circuits shorted out the computer, in addition to the highly volatile at room temperature.
Be the participants were forced to pour liquid nitrogen slowly and in a certain time interval as needed into the container named “bong” is affixed to the surface of the processor.
Her whole body bong made of aluminum or copper metal coated with insulating material to prevent water condensation dripping onto the bare PCB boards around it.

Liquid nitrogen is stored in a large tank designed specifically to accommodate the gas. When about to be used, the liquid nitrogen must be transferred into another smaller tank, before being transferred back to the flask.
Thermoses is used as the final container before pouring liquid nitrogen into a bong. A number of empty beer bottles strewn size pint looked at the table some of the participants. Either it has been poured into a bong or abdomen to overclockers.
Because of the cold of liquid nitrogen, some of the runners carrying a portable welding tool or torch to raise the temperature of the processor when needed since the system can also crash if too cold.
The fire of the tool was poured into a bong-to the same place with location-pouring liquid nitrogen to increase when the temperature dropped too far as a result of liquid nitrogen.
Balancing the temperature is one of the biggest challenges in overclocking, not to mention all sorts of other parameter settings that can affect the stability, such as voltage magnitude, frequency memory, and so on.
In addition to the participants, space bar is used as the overclocking arena filled with hundreds of others. There is a host of the show, the organizers were busy pouring liquid nitrogen, to busy reporters covering the race.
"I’ve heard no one can reach 4.5 GHz, 4.7 GHz, let’s move on, do not give up!" cried Lisa Graff, group vice president and general manager of the PC Client Group Intel Desktop Client spark from a stage, cheering greeted the participants.

When the contest ends midnight, a record for the highest frequency successfully etched. Frequency of Core i7-4790K managed to be boosted up to 6.3 GHz with liquid nitrogen cooling. A participant who wears aircooling managed to force the processor that runs at the speed of 5.5 GHz.
