I went into MSI Afterburner and I checked the box that says "unlock voltage". I also restarted MSI afterburner but the voltage is still locked and I cant up the voltage! I increased the core clock and its unstable and in need of voltage increase! I know that changing the voltage is possible because it was done in this video...
