To overclock the Gaming Z, we used MSI Afterburner. We maximised the power limit and temperature target sliders, before adding +40MHz to the core and +700MHz to the memory. This isn't a whole lot of extra clock speed – but we do have to remember the Gaming Z ships with a fairly aggressive factory overclock in the first place, so manual overclocking headroom is limited.
3DMark and Games Testing
This overclock – even if not hugely significant – still brought some decent gains. We saw our frame rate jump up by about 4FPS when gaming at 1440p, while our Fire Strike score also rose over 1200 points – a 5.4% increase.
