i5 4670k 4.5ghz need help with some voltages !

I was messing with my i5's 4670k settings so that i can overclock it from stock all the way up to 4.5ghz , and ive succeeded.

But... the smallest voltage that i was stable with was 1.278v.

Is there any other voltages that i can mess with maybe i will be able to run my cpu at 4.5ghz with just smaller v core ?

All voltages are on auto except for the cpu input voltage (1.9) and the vcore (1.278).

Cooler is Coolermaster V6GT. Temps gets high with prime95 , but during BF4 with high settings the highest it gets is about 80degrees.Most of the times its 60-75deg.

Can this be my chip ? Maybe i got one of the unlucky chips that cant get any lower voltage with such clock ?

Your chip is preety good. A sucker haswell would not be able to go past 4.3 or it would reach 4.5 at 1.3 or above voltage. I don't think you can reduce the voltage if it bluescreens under that level.

Don't be so disappointed! 4.5 GHz on 1.278v. is a very good result.

Try reducing your cache/ting ratio to 35-38, and set cache/ring voltage to 1.190v. on Override.

So cache ratio to 38 and cache voltage to 1.190 ? Whats the difference in cache ratio from auto to 38 ? What is cache ratio ?

"Cache Ratio" determines the frequency of the "Ring Bus". The Ring Bus connects the CPU with the caches. Similar to adjusting the CPU frequency by setting the CPU ratio, you set the frequency of the Ring Bus by setting the "Cache/Ring Bus Ratio". The ring bus operates at a multiple of the Base Clock (100Mhz) so setting the ratio to 38 will give a Cache/Ring Bus frequency of 3.8 GHz.
