Gigabyte Z170X-Gaming 7 Motherboard Review

Automatic CPU Overclocking:

UEFI-OC

Gigabyte provides a number of CPU overclocking pre-sets through the UEFI although these use pre-defined settings rather than ones tweaked to an individual chip's capabilities.

EasyTune-Auto-OC-4_7GHz

Using the Auto Tuning method in Gigabyte's EasyTune software our chip managed to run at 4.7GHz with stability. The software cycled the chip's frequency and rapidly stress-tested it until the system crashed. Upon reboot the previous information was used to run the CPU at a relevant stable frequency.

Core voltage for this automated overclock was a positive. The chip was set to operate at 4.7GHz with a core voltage of 1.288V under heavy load. This resulted in positive temperature and power consumption numbers. One disappointment, however, was that XMP was disabled.

Manual CPU Overclocking:

To test the Gigabyte Z170X-Gaming 7 motherboard’s CPU overclocking potential, we first increased the CPU VCore to 1.40V. We also enabled ‘High’ load-line calibration (LLC) in order to supply as close to our selected voltage level as possible. The cache ratio was set to 45x.

4800MHz-load

Gigabyte's Z170X-Gaming 7 motherboard had no problem pushing our i7-6700K chip to its stability limit of 4.8GHz when using 1.4V. Voltage accuracy using the High LLC setting could have been better – our multimeter recorded a VCore of around 1.385V whilst idling and around 1.37V when under heavy Prime95 load.
