Eight-core Core i7-5960X overclocked to 6GHz+ with all cores active

Although Intel Corp. decided to set pretty moderate default clock-rate for its eight-core desktop chips aimed at performance enthusiasts, the new Core i7-5960X “Haswell-E” central processing units appear to be pretty good overclockers. Recently a German enthusiast managed to boost clock-rate of the new processor by two times from default using LN2 cooling.

Der8auer, an overclocker from Germany, on Monday overclocked his Core i7-5960X microprocessor from 3.0GHz to 6065MHz, based on his submissions on Hwbot.org, a web-site that overclockers use to share their overclocking results. It is especially noteworthy that all eight cores and the Hyper-Threading technology remained active, as a result, the chip could demonstrate record performance in various applications.

To overclock the eight-core CPU, Der8auer used Gigabyte X99-SOC Force LN2 mainboard based on Intel X99 core-logic set as well as liquid nitrogen (LN2) cooling. The core voltage of the chip was increased to 1.657V, which is not too high.


The record overclocking allowed Deb8auer to set three world’s records for eight-core microprocessors:

  • HWBot Prime – 9698.75 points at 6065MHz;
  • wPrime 1024M – 58.380 seconds at 6065MHz;
  • Cinebench R15 – 2342 points at 5875MHz.

While 6GHz is extremely high clock-rate, it is not the record frequency ever set by the Core i7-5960X chip. Recently Nick Shih, a well-known professional overclocker that works with Asrock, managed to overclock his Intel Core i7-5960X processor to 6594MHz with LN2 cooling on Asrock X99 OC Formula mainboard. He had to increase core voltage to 1.818V and disable seven cores out of eight.

KitGuru Says: The new enthusiast-class processors from Intel overclock very well with LN2 cooling. Unfortunately, far not all of such chips can operate at 4.5GHz+ with proper air or liquid cooling.
