BIOS and Overclocking
Gigabyte’s BIOS always enters you straight into the splashscreen from which you can pick from key tiles or select which BIOS you want. Gigabyte use their “DualBIOS” design which means you can pick from a visually attractive UEFI option or a more traditional AMI legacy BIOS.
In the UEFI we find a full HD, 1920 x 1080, display which gives you lots of information to help you visualise your system. Below you can see our overclock settings where we simply dial in a 48x multiplier and 1.3 core voltage: we’ve extensively tested our i7 4770K and know what this CPU is limited to on our test system.
The legacy style BIOS is what I personally prefer, I feel more at home here but each to their own. At least Gigabyte give you the choice to pick between the two competing styles.
Overclocking
As already mentioned the CPU managed 4.8GHz at 1.3v core voltage: this is a CPU limitation. For those who don’t know, Haswell and Haswell Refresh overclocking on the LGA 1150 platform is largely limited by the CPU due to the onboard VRM controls.
