can't past over 4.4 i5 4670k

[oldschoolh]

Hi All,

After 2 month trying to find best clock I stuck at 4.4ghz..
1.26 bios manuel vcore,digi+ options are all extreme,SVID disabled,LLC 8,on xmp(1866 2x4)
On full load it is 1.28 and fully stable..

I can boot with 1.2 vcore 46x successful I think I have a good batch but there is something I missed.
Can't pass over 4.4 even 1.31-1.35 vcore..It crash with prime or occt..

Any advice?
Thanks.

VI Hero

I would suggest that your CPU needs a huge amount of extra voltage to make the step up to 4.6GHz stable. I do not think it would be worth it to even worry about it.

You can test this of course. If you cooler is up to the task just use 1.4 volts and see what your system does multiplier wise.
