to go over 4.6ghz i had to tweak some other bits not just rely on cpu voltage
llc and cpu current capability and vrm fixed frequency mode i think
at least you have very good cooling on there
4.6ghz to 5ghz isnt a huge performance increase anyway
but its nice to see the magic 5ghz
my 2600k will go over 5ghz but the voltage increase and extra heat just doesnt justify the extra 200mhz
