Daniel Schier, AKA Dancop, has achieved a new SuperPi 32M record using the Intel 8700K processor clocked at 7.4GHz. He used a few unusual techniques that helped him find the edge on his overclocked rig.
The stock frequency of the processor of the Intel 8700K is clocked at 3.7GHz with 4.7GHz in boost mode. Overclocking the processor all the way to 7.4GHz was no small feat. Daniel opted to disable half of the cores and hyperthreading for a balance between performance and stability. A stock 8700K has six cores and hyperthreading by default so he limited the build to three cores with no hyperthreading.
The SuperPi 32M record that Daniel accomplished was a 24-iteration test that was completed in 4 minutes, 7 seconds and 609 milliseconds, while the runners-up score was about half a second slower.
A 73.0 multiplier was used to bring the CPU up to 7.4GHz, while the voltage was set to 1.984V. The dual-channel 16GB (2 x 8GB) DDR4 memory was set to 2078MHz with timings of 12-12-12-28-1T. To keep the CPU and memory cold enough for the extreme overclock, Daniel used a liquid nitrogen cooling rig, which gave his rig a snow landscape look.
One of the more interesting things about his setup was that he used a Z270 chipset motherboard, which normally would not be compatible with the Intel 8700K. Overclockers often find ways to use older boards for increased stability. The motherboard in question was the ASUS Maximus IX Apex. Another odd choice was Windows XP as the OS for the build. Microsoft ended official support for Windows XP over four years ago.
Just last month Daniel won the G.Skill OC World Cup, which earned him a grand prize of $10,000. He also announced that he will be retiring from the competitive overclocking scene after winning the prize.
