Gigabyte Z77 Overclocking Guide

When we first postulated an article such as this, we chose to stay within the 4.4GHz boundary. It's achievable on almost any processor at all, and doesn't require extraordinary voltage or cooling to attain. Having got 4.4GHz from only a 0.05v bump in voltage we were tempted to see how much more could be had without remotely out-reaching a level of vCore that first timers would be comfortable using. It's also important for us to not do what a lot of guides do and start with a 100MHz overclock and, within a couple of CPUz's, be a 6GHz on LN2.
Retaining the exact settings we've used so far (Turbo off, Loadline calibration to Extreme, manual voltages, CPU @ 1.18v) we bumped the CPU Clock Ratio up from the 44 we left it on to 45. Yet another reboot and off to make a coffee whilst OCCT does its thing, and things are looking rosy.
46 Ratio giving a 4.6GHz CPU speed fell over at the forty minute mark in OCCT, but a final increase of the CPU vCore from 1.18v to 1.2v saw things fully stable, and that's where we'll leave our overclocking adventure. We think you'll agree that 0.07v increase, for a 1.1GHz overclock above stock, isn't bad going at all.
Now let us remind you of why "Auto" is evil, and should never be relied upon.
