Well it's definitely running stable now. Does this mean when I get a video card I should be able to swap it back over to automatic?
Yes thats what im doing now running auto overclock of 4.6 but i can only do that because im using discrete video card and also you will see better performance when your not using your igpu.
when i tried a 4.6 auto overclock using the igpu it just wasnt stable but now im using discrete card 4.6 overclock is stable.
