overclock no longer stable

[star_weaver]

for like 2 months or so i had a 100% stable overclock, i5 4690k @ 4.8 Ghz and now i can barley pull 4.5 on same voltage, temps are fine without going over 70c on 1.45v with a long session of stress testing,~4hours

1.45v, not the most desirable setting.  It might be the reason for the now unstable clock.  That is way more juice than OC'ers here would recommend for a 24/7 OC.  <<I might be wrong

 

Normally 1.3v or less is the 24/7 voltage recommendation.

so should i up the voltage or make it go down

I would revert to stock settings, and then test it.  If it unstable, contact Intel and try to get a new CPU.  They do exchange CPUs that are damaged.

 

If it is stable, then do the overclocking again.  BUT... do not throw 1.45v at the thing for a 24/7 overclock.

It sounds like you've deteriorated the CPU pretty bad there.

so i should try a 1 Ghz overclock on stock voltages then?

no

[star_weaver]

everything on stock is fine though

Oh, ok...

 

Sure, try to gauge how much you can OC... but stay under 1.3v. 

[star_weaver]

ok

[Coaxialgamer]

1)Your OC never was stable and you just crashed

-or-

2) You are using too much voltage , which causes the transistors to deteriorate , and require more voltage to operate

1.45v on an intel chip... where did you see that was safe?

Lol and my Intel I7 3930K doesn't even reach that on 4.7.
