I have a Lenovo legion y520 gaming laptop with a i5 7300hq and a amd rx 560 4gb video card. 16gb of ddr4 2400 MHz ram. I want to know how far I can raise the core and mem clocks using msi afterburner? here are the stock clocks. core-1202 mhz. mem-1500 mhz. also im unable to change the voltage, I tried a lot of things including modifying the registry.
