trying to OC my old i5 2500k to 4.5ghz.
Following are the bios settings
Cpu voltage 1.350
load line callibration Extreme (100%)
C states and intel speed step are off.

Under stress pc is completely fine .Tried 4 Hours Aida64 cpu , fpu , cache and memory stress no issue at all.
Left pc at idle for 2 hours and came back and my pc was completely Froze.
Any Suggestion will be appreciated.
Mobo Asus p8z77-M Pro
Temps are fine max 72 degree after 4 hour aida64.

is it a bad idea or will it work ?
Well it's not a great idea...

With 1.35V on a 2500K, you're looking at probably 150W (+/-), a 3GB 1060 can draw ~120W. Few watts here & there for RAM, SSD etc.

I'm assuming the PSU is an Earthwatts Green 380W? Which could do a max 336W on the 12V rail, when new.
That's an old PSU, which may well have degraded to a point it can't do the spec'd 336W.

As mentioned above, Extreme LLC is not for 24/7 usage and it likely won't be helping the situation here.

yeah , its the green psu.
just dropped the multiplier to 44 bcz i cant get it stable st 45. ( i think its just a degraded chip).
the pc just crashes while idle ? (Its Whea uncorrectable error)
tried prime 95 4 hours blend no crash but at idle it crashes after 2 hours ? thats a weird issue.
Also i am gonna try using my pc as normal ( Games , browsing etc).
If it gets any sudden reboot , system crash , i will buy new psu.
Thanks for Helping , sir.
