    [News] Core i7-8700K Overclocked to 7.34 GHz (3c/3t) on Z270 Chipset, Bags SuperPi Re

    https://www.techpowerup.com/245689/c...superpi-record

    German professional overclocker Dancop got the Intel Core i7-8700K processor to work on an ASUS ROG Maximus IX Apex (Z270) motherboard, something that's not supposed to work. CPU-Z screenshots seem to confirm this unholy union between the 6-core "Coffee Lake" processor and a 200-series chipset motherboard, using a custom "0084" BIOS dated 11th June, 2018. Dancop then proceeded to overclock the chip to 7344 MHz using extreme cooling, and 2x 8 GB (dual-channel) DDR4-4000 memory. This bench-stable build was then used to bag a SuperPi 32M world-record.

    There's a rather big catch, though. Half the cores on the i7-8700K were disabled, and so was HyperThreading (not that it's relevant to SuperPi). The 3-core/3-thread chip was still bench-stable at 7344 MHz, crunching SuperPi 32M in a world-record 7.609 seconds. The clock speed was achieved by dialing up the multiplier to 73.0x, with the base-clock probably untouched, at 100.61 MHz (with the +0.61 MHz probably being variance). Supporting this clock was a blistering core voltage of 1.984 V. A liquid-nitrogen evaporator was used to tame the CPU and motherboard VRM. Find the validation in the source link below.

    Wow next stop 3 min! When i used to run 32M I think it took 32M LOL

    Edit - Just noticed those memory settings!

    No surprise it runs on z270, but would have expected those clocks on an i7 8086k. Lots of people are worried the expected 8 core coffee lake will not run on z370 but this post proves anything is possible, z170 on 8 core
