Meanwhile, I also made sure that the CPU temperature wasn't fluctuating too much by occasionally refilling the pot (thankfully, G.SKILL had plenty of liquid nitrogen to share). As I was going from 55 to 65 for the CPU ratio, I went up by increments of two units each time before hitting the "apply" button, and I would always wait until CPU-Z reflected the new clock speed before applying my new settings. Plaisier set me off with a couple of settings in TurboV Core: He bumped the CPU ratio to 55 to reach 5.5GHz clock speed (this is derived from the 100 MHz default base clock), then he also pushed the CPU core voltage to 1.855V. Once the pot reached just a little below -190☌, the liquid nitrogen stopped boiling frantically, and this was when I could actually start overclocking. My instructor, HWBOT director Pieter-Jan Plaisier, started by running Cinebench in Windows to ensure the CPU's stability while I slowly poured liquid nitrogen into the pot. The main objective of the workshop was to push the CPU from its 4.2GHz base frequency all the way to 7GHz, and this required lowering the CPU's temperature to nitrogen's boiling point -195.8☌ or -320.4☏ - in the first place. To keep track of the CPU's temperature, an industrial thermometer was hooked up to a thermal probe inside the liquid nitrogen pot.
#CPU Z OVERCLOCK SOFTWARE#
The monitor was showing the ASUS TurboV Core software along with CPU-Z - the former for accessing various CPU parameters, and the latter for keeping an eye on the CPU's status. There was a fan hanging off the pot to suck vapor away, in order to avoid condensation on the motherboard.
#CPU Z OVERCLOCK PLUS#
At first sight, I was slightly overwhelmed by the setup in front of me: I was staring at an ASUS ROG Maximus IX APEX motherboard, which carried two 8GB G.SKILL Trident Z DDR4 RAM sticks, an Intel Core i7-7700K plus a chunky copper pot directly on top of the CPU to hold liquid nitrogen. Rather than getting me to build from scratch, the instructors had already put together a rig that would let me dive right into the overclocking process. The one-on-one workshop was jointly set up by G.SKILL and overclocking-enthusiast group HWBOT.
