Ok so im trying to do some overclocking with this card. I tried on MSI Afterburner but couldnt change voltages or power usage. So I also tried PrecisionX and it lets me change those two settings i just dont know how much i should do each one. Ive watched some of Jayztwocents videos on overclocking but the interface on his videos is a tad different so i cant be sure of what im doing.
