4670K overclocking help

Fairly simple sync all cores, multiplier and voltage. On my GB board 4790K running 4.6 I'm at 1.22 volts. Unless your just trying to get the max overclock you can their really no reason to change anything else unless you run into instability issues.
 


I set sync all cores, voltage to 1.250 and actual clock to 4.5 and 4.4, other didn't boot into windows and other bsod ten seconds of prime95

Do i need to tweak bios more to get 4.4 or 4.5?
 
May need more vCore, (CPU voltage), each 4670K is individual and will require different amounts of voltage for a given OC. Also not all can clock as high as others, Silicon Lottery. Below is using 4770K but same true of all CPU lines.
