Overklocking - ok with auto voltage?

[MightyNerd]

Hi, I'm overklocking my 2600k on a MSI P67A-GD80 B3 and I wonder if it's ok to leave the core voltage and auto. After a few searches, I found out that most people say that auto voltage usually overvolts the CPU but CPU-Z reports about 1.240 - 1.248V on a 4.4GHz overklock which doesn't seem high, does it? My temperatures are under 63 degrees C with Prime95 and the system seems stable (I've only run Prime95 for about 20min but I will of course run it for mutch longer when I'm done).

Most people seem to recommend the vcore offset mode but it doesn't seem to be available with my board as far as what I've seen. If you think I should use manual voltage instead, what voltage should I start with?

Just to be sure, if you're happy with 4.4GHz, lower the voltage slightly manually and see if it is still stable. If it is, then great, if it isn't, then auto-voltage worked well for you.

yea just keep lowering it slowly, and stress test every adjustment you make until either you're happy or you've hit the limit.

I use auto-voltage for mine as-well, my voltage doesn't go above around 1.220v.

Theres no harm in using it if you are getting low voltage levels.

Thank you for your replies! It seems to be ok at 1.25V (CPU-Z reports 1.24V) and I'll probably stay here. But I wonder if there is a way of lowering the voltage when the CPU is on idle? Without Prime95 running, the core speed goes down to about 1.6GHz but the voltage stays at 1.24V. It seems like I would need to use offset voltage mode which I don't think I have on my board (unless it's hidden somewhere or named completely differently).

I believe in your BIOS there should be an option along the lines of 'Power Saving' or something like that, not exactly sure though, wait for the pros!

i don't trust auto voltage cause they make the voltage bigger then the cpu needs

NO! Never let your board decide! If you OC to more than 4.5Ghz your board could kill your chip with voltage, one guy OCed his i5 to 4.8Ghz on auto and the board overvolted it to 1.56V...
