I have a 2600k OC'd to 4.8GHz and I had to set the voltage to 1.44 so that I won't get the blue screen while trying to run Prime95 I feel like it's due to my vdroop (btw I don't feel comfortable having to set my voltage so high due to this problem). I have the AsRock Z77 Extreme 6 Mobo and I set the VCore voltage to 1.44 like I said yet on idle without any applications running, I'm at 1.415V and with Prime95 running it goes down to 1.338V after a couple minutes. Any suggestions that might help?
It's set to Auto by default which is most of the time level 5 as far as I know. What would be the best way to OC? using a fixed CPU ratio with a fixed VCore? or using a fixed CPU ratio with an Offset VCore setting? or what?

Are you talking about enabling/disabling SpeedStep? If so, I recommend leaving that enabled (at least after you get to a stable OC) because it allows the CPU to throttle down and save power an creates less heat.
As far as voltage goes, I recommend using offsets for the same reason. With a fixed voltage, the CPU will be at whatever voltage you set it at constantly, creating more heat needlessly, even if SpeedStep is enabled and the CPU drops to 1.6Ghz idle.
Also, I think Level 1 is the highest LLC setting on that board.
Close from the bios Intel speed step, Enhaced halt (c1E), Thermal Monitor, turbo boost, etc…
Lower the volts to your cpu 1 step at a time and run a prime95 torture test 4 threads with minimal fft 8192 (8Mbytes all your cpu cache), half the ram usage. If the voltage is wrong you will lose 1 core with error pretty quick this way less than 2 minutes usually the last one….
Continue the same procedure as loop until you will find the lowest operational volts for your i7 2600K at 4.5 Ghz finally you will lose a core with error. You go back to the bios and set the voltage one step back you done.
I run my cores at 3 Ghz idle I don’t need ‘helpful’ vdrops…
