Unstable Vcore - I5 2500k and P8Z77-V

post #1 of 5
Thread Starter 
Hello everybody. I have been trying to overclock my new i5 2500k, and that is my first Overclock ever.

After reading lots of guides here, i learned how to overclock it, and got my cpu to 4.5Ghz @ 1.328V (My core number 4 seens to be quite weak, as it always fails with lower voltages.)

The problem is with my motherboard Asus P8Z77-V when i use the Offset Mode.

No matter how much i try to tweak the Vcore or the LLC, CPUZ and HWMonitor reports peaks of 1.336v under load. When idle it has a nice low Vcore (dont remember the number right now).

Btw, im running Prime right now, 6h so far w/o any errors. It is Air-Cooled. Avg. Temp: 63C°. Max. Temp: 70C° frown.gif

And my case isnt even closed yet (my old one is too small, will get a new one soon)

Any idea of what to do? Is it safe to keep this way? It is a Gaming computer, and it wont even stay on 24/7. Thank you for any help.

Anyway, my Complete Specs are:

Intel I5 2500k
Asus P8Z77-V
2x4Gb Corsair Vengeance 1866Mhz
Corsair GS800
Cooler Master V6GT
Antec Formula 7
Seagate Barracuda 7200.12

1.336V at 70C is nothing to worry about.

Welcome to OCN smile.gif

Those are very good temps for 4.5GHz & you would never put a load on the CPU as Prime95 does when gaming.
So its a nice oc with decent temps. My guess it would never go above 55c when gaming thumb.gif

Btw, to put your rig in your sig:

Thank you a lot. So if the temps dont get high (in games is usually is 55C°), those voltage variations wont do any harm?

No, they're fine.
