On Saturday 10 July was on the old T. just-headquarters in Amersfoort, a overklokcompetitie place, where the participants loose allowed to go on the easy overklokbare Core i5 655K and i7 875K-cpus from Intel.
In the preliminary round was overclockers on GoT asked for chips based on the socket 1156 platform as far as possible to overclock. Dualcores were then the Super Pi 1M benchmark tested and quadcores were subjected to Wprime 32M. Cooling only with air and water was allowed. Sub-zerokoeling was excluded, because the K processors more on water and air cooling have focused on extreme overclocking. Nevertheless, there was also a third category, in which users any 1156 processor with all the available resources were to increase.
For each of these three categories, two overclockers invited to the at the office of T.net against each other. They were available on Intel’s Core i5 655K and Core i7 875K processors. These Clarkdales and Lynnfields were in Asus Maximus III Extreme motherboards inserted. Corsair provided XMS memory, and the TX950W and HX850W power supplies. Asus had for the occasion, Geforce GTX470 cards delivered. The operating systems, Windows XP and Windows 7, on Intel’s X25V ssds of 40GB installed.
Just as the first round was the final in three groups divided: one for the Intel Core i5 655K, Core i7 875K, and finally the free competition with the Core i7 875K. The finalists, pascalhaegens and Kobus71 in the 655K category, BTU_Natas & Xtrafris in the 875K-group and Thijszor and Viss in the exceptional category, had two run benchmarks:

i5 655K
Pascalhaegens and co-overclocker Michel klokten their air-cooled 655K cpu under Windows XP on 5112MHz and did Super Pi 1M in 8,125 second. For the 32M WPrime-bench, Windows 7 started and it was the cpu also 5112MHz clocked. In that setting, could the benchmark in 9,422 second to be rotated.
Opponent Kobus71 made of a Mugen 2 cooler use the Core i5 665K to keep them cool and to 4515MHz to clocks. At that speed could Super Pi 1M in 9,578 second to be completed. With a slightly lower clock speed under Windows 7 could WPrime 32M in 14,743 second be rotated, with the cpu at a clock speed of 4365MHz.
i7 875K
With eight Sanyo Denki San Ace fans that a double radiator, and knew Xtrafris & BTU_Natas their Core i7 875K under Windows XP on 4767MHz to clocks. That speed was sufficient to Super Pi 8M in 1m 52,031 s to run. Although the core-voltage a not sick 1,608 V was kept the water-cooling the temperature of the cores also under load is well below the 80 degrees. Under Windows 7 was the cpu test of 3DMark Vantage is rotated, whereby the processor speed to 4497MHz had to be lowered in order to safeguard stability. The 3DMark score came on 27.413 points out. Competition in this category was due to holidays, unfortunately not.
LN2
In the outside category names Thijszor and Viss against each other. They each had a Core i7 875K cpu at their disposal, and, of course, had Tweakers.net for liquid nitrogen is provided.
Viss knew his 875K under Windows XP to just above the magic 5GHz threshold to clocks, namely on 5052MHz. The required voltage at the processor was 1.616 V only marginally more than the water-cooled processor. Over 5GHz was sufficient for a score in the Super Pi 8M-a benchmark of 1m 32,141. For the processortests of Vantage under Windows 7 also had Viss are cpu speed lower to 4748MHz. At that speed put the 875K a 3DMark score of 29.138 points down.
Thijszor tried Viss fire to the shins, but also after repeated changes of hardware continued to be problems. The high ambient temperature played him probably tricks and made possible for too much condensation on his setup. Unfortunately he could not score drop.
The overclockers were allowed virtually all of the hardware used, including the used processors, motherboards, graphics cards, memory and power supplies and solid state drives to take home. In addition to the overclockers we like Intel, Asus and Corsair thank you for the provision of all hardware. Of course we want the winners pascalhaegens & Michel, Viss and Xtrafris & BTU_Natas congratulate for their victory.
