So i re-applied my thermal paste and changed my voltage so i get 1.052 at 100% load at 4.2 ghz. As it turns out, my overclock yesterday was not as stable as i thought and by changing the voltage it made it work better. I heard that anything under 1.2-1.3 on an i5 3570k is safe so at the moment, i think my overclock is in the safe zone. Hell, when i ran stock, voltage got to 1.048. Can someone confirm if the voltage is safe as a second opinion. I asked this question yesterday, but that was with a different voltage.
