I've been trying to get my 4770k stable beyond 4.4GHz. I have a sufficient power supply and a good MOBO. I've been playing around with many different settings but nothing seems to get it stable past 4.4GHz, at least not for any useful amount of time. I have a Tripp Lite UPS that displays the voltage from the outlet. The battery backup is rated at 600W, and the unit has surge protection, and noise filtering. With the new house that I'm in, the voltage is constantly fluctuating, like every second. On a good day it will vary anywhere from ~109-125V but I've seen it go from 95-135V every once in a while.
To sum it up, I'm wondering if having purchasing a voltage stabilizing unit could solve my problem. I'm aware of the silicon lottery, but I wanted to try one more solution before I just left my processor as is.
