Overclock already maxed?

[pants18]

Finally got rid of my stock cpu cooler for a 212 evo today to cool my fx-6300 and attempted to oc it with gigabyte's uefi. I got it running stable at 4.6ghz but when I increase the cpu ratio clock to 4.7, I get an error message on boot saying something along the lines of "system has experienced a boot failure possibly due to incorrect configuration". The only options from there are to boot back into the bios, or boot into windows with default clock speeds (I tried inching up the voltage until I reached 1.6v so thats clearly not the issue). Any ideas on whats causing this? Or have I reached the max overclock possible with this chip

If you want more, more voltage then

would prefer not to wreck the chip or my vrms... does it sound like a voltage issue though?

you are most likely hitting the limit of your chip 

a hyper212 is certainly better then stock but it may not be up to the task of keeping a fx 6300 under 70c when oc'd to 4.6Ghz

not a thermal issue though; at 4.6 my cpu only reaches 55c under load with prime95. guess ill just have to leave it at 4.6ghz and be happy with that

Yeah man sometimes a processor just doesn't support going any higher on frequency than a certain range... hell I've known people who bought 4770K's that would only go up like 200 MHz before they hit their brick wall.  You are only ever guaranteed by the manufacturer to achieve the advertised clock speeds, so anything extra is a matter of how good a chip you got.
