Core i5 2500k safe 24/7 overclocking @ 4.0-4.5 GHz

1555 7
Hello people!!

I have a question regarding the i5 2500K oveclocking @ 4.0 GHz or max 4.5GHz BUT consider that i need this thing for 24/7 so i dont want to stress it much. Running full load in stock clocks brings me the temperature of 58C on cores and 47C on CPU and idle on cores is 29C and on CPU is 20C.
Im reading generaly that the only thing to do to get it working above 4.0 GHz is by switching the multiplier to 40x and up, then save bios and exit, but im sure its not only this...

Thanks in advance for your answers!

No problems detected after 20 linX runs with 4096k memory used while the cpu-z shows 1.056 core voltage, bios says 1.296 Vcore, the cpu running @ 4.0GHz with 40x multiplier with 1333Mhz stable ram, auto CPU PLL, disabled intel turbo boost and everything else on default. The temps on cores are max 65C and average 58,4C and CPU temps max 54C and average 48C.

Tell me your opinions on that

Read the guide?
overclocking voltages on auto can be dangerous sometimes

Ok, because of the low Vcore voltage in Cpu (1.296v) nvidia driver crashed and recovered by itself. So i've turned it to auto tested with prime95 for 10 hours 0 errors 0 warnings. The settings for 4.0Ghz that worked for me are the below:
Multiplier -> 40x
RAM -> 13.33
Voltages -> AUTO
disabled the CPU PLL, Intel turbo boost and the change in core clock inside the OS.
Everything else stayed on defualt and auto.
Max temps were 54 for CPU and 66 for cores after the 10 hours of testing.
