my 9600kf was able to do 5ghz with 1.35v for the first year, and i’ve had to lower the clocks again and again as it gets unstable. it’s now only able to do 4.4ghz. recently upgraded to 7800x3d and i’m afraid to see how long this one lasts as it’s 5ghz stock and gets quite warm even in light use. performance is amazing though, realized my old cpu bottlenecked in many games.
