HI all, I have a MSI Z68AGD55 B3 motherboard and I 5 3750k, I have had this cpu overclocked to 4.5 ghz stable for month or more no problems but I had to crank the voltage way up to get it stable compared to what others out there have there voltage set at to get 4.5. I understand the v droop and such to some degree , all my bois allows is to set it at a % not low high and such. I still get huge v droop I have it at 1.35 v and drops way down around 1.26-1.28 v but even at these settings prime 95 run for hours temps are at 68c max is my cooling that good with the cooler master 212 evo? or are my voltages wrong. My case is full tower nzxt phantom full of fans as well. I am happy with this as my first build and all but still wondering why I have to crank voltage so high
