On a chipset that is not compatible!
The professional overclocker Dancop has managed to run an Intel Core i7-8700K on an ASUS ROG Maximus IX Apex board , that is, a Z270 board , something that the hardware gods do not allow. The captures of CPU-Z seem to confirm that, indeed, this six-core Coffee Lake has worked on this plate thanks to a modified BIOS "0084" dated June 11 of this year. After carrying out this abomination of nature, Dancop has overclocked the processor to 7.34 GHz (7344 MHz, to be exact) with extreme cooling and using two 8 GB DDR4-4000 memories. This test table has allowed him to break a world record of SuperPi 32M .
But, but , the thing has a trick. The half of the core of the i7-8700K were disabled, like the HyperThreading (although that does not affect the time of qualifying for SuperPi). The three-core, three-wire chip was stable at those 7344 MHz, surpassing the SuperPi 32M record for 7.609 seconds . To get to that frequency Dancop has increased the multiplier to 73.0x, probably without touching the base frequency, at 100.61 MHz. To feed the winning frequency the necessary voltage was 1.984V , and the cooling has been exactly an evaporator of nitrogen that was applied to both the chip and the VRM of the plate. In case you feel more like overclockscrazy, we remind you that recently, Der8auer took the recent i7-8086K at 7.24 GHz and young Ryzen 2700X at 6.0 GHz .
