Hey Duders, I'll be streaming a playthrough of Star Wars Rebel Assault 2 shortly, It's a fun game with a dumb story. If you have nothing better to do come watch me fight the mouse controls in this game.
Most likely you have to do it manually on your bios and adjust the voltage. When I bought mine I also tried setting it to 2400 but it didnt work. I went with 1600 and worked fine and can't really complain about it.
If you know nothing about it I wouldn't recommend messing around too much, research how to do it properly for your brand/model first.
