When Setting vCore i am supposed to drop my voltage by one notch. Exactly what is a notch? My BIOS will only let me drop in chunks. I started at 1.3500V and the next lowest voltage is 1.3375V, 1.3250V, 1.3125V, 1.3000V, 1.2875V
Seriously all you can do is go to the next lowest setting as you search for the lowest Vcore setting to reduce unwanted heat but that will be stable with your OC. After testing you might have to bump it back up.
1 bump = 1 notch = 1 chunk
Be gald we are not adjusting by RCH's , find an older engineer and ask what that is, I dont want to say in here.
