It could well be that you have reached your CPUs own limit, and that is that. Not all CPUs can be overclocked as much as others, even units that originate on the same wafer can overclock differently.

Upped voltage to 1.425V, memory set to default values. Anything else I should be doing?
Thanks for your help.
anything past or leading to 4.4ghz needs to be 1.44 to 1.45 your voltage is too low that is why you are failing prime voltage needs to be up to atleast that much

Thank you Solarstashines and Dwarf. For some reason I wasn't getting notifications for this thread.
Solar, later I will try upping the voltage to the values you suggest. Will update when I'm done testing stability.
Right now I'm very tired from moving to a new case.
Tanks again,

Solarstashines,
Achieved 4.525K stable following your advice, but the thing got too damn hot, it touched 59 C after like an hour of p95 and it idles at around 38-39C vs 34C at 4300K. I need better CPU cooling for using this OC 24/7.
I'll stick to 4300K for everyday use till I get a better air cooler or go liquid.
Thanks for your help.
J

Were all glad to know that you achieved it! Solar had lots of success with that chip and i was sure that others would too.

The one I have is way better than the hyper 212+ or evo, although it is cheaper.
Thanks for your help Pedro.
