The following configuration is something which works on MY hackintosh.
It might not work on other systems and it might harm your computer.
I did do some old fashioned screen shots as the bios do differ a lot though.
Dynamic Vcore (DVID) +0,000V (you might need to increase this by +0,010v till your system is stable)
Best done under windows as the tools are just better there.
Overclocking the PowerColor Liquid Devil is easy, it is Overclocked out of the box 😀 At least if the Bios Setting is set to OC.
But you can even go faster by switching to the Unleashed Bios.
