OC Menu
This menu allows you to configure the frequencies and voltages for overclocking.
Please note that, higher frequency and voltage may benefit overclocking capability but
cause system un-stability.
⚠
Important
Overclocking your PC manually is only recommended for advanced users.
∙
Overclocking is not guaranteed, and if done improperly, it could void your warranty
∙
or severely damage your hardware.
If you are unfamiliar with overclocking, we advise you to use GAME BOOST function
∙
for easy overclocking.
