Safe voltage for a 2500k on my Gigabyte mobo?

[Red Hawk]

I recently got a new rig with a 2500k, and I've overclocked it to 4 GHz. I have no real reason to go higher, my rig will GPU bottleneck at most games long before CPU bottlenecking. For the overclock, I simply turned up the CPU multplier in the BIOS to 40. I changed nothing else. It seems that automatic voltage adjustment is enabled in the BIOS, and CPU-Z indicates that the voltage goes up to 1.44 V when the CPU is under load. Is this a safe voltage, and is it overkill (meaning I should disable automatic voltage adjustment and manually set a lower number)?

Voltage is not going to kill your chip, but it's way too high. You could probably shave off .07 to .1 volts and maintain your clock.

1.44 is very high and is insane for just 4.0. 1.22 or so would be all that's needed for 4.0.

Thanks for the tips. I tried going in to the BIOS to adjust the Vcore manually, but Gigabyte's BIOS seems a bit weird in that it doesn't let you adjust the Vcore directly. I read online that it allows you to adjust the Dynamic VCore offset, and the only way to tell if that's giving you the voltage you want is to check the general system status in the BIOS. The guy writing this also said that third party apps don't seem to detect quite the right current voltage, so CPU-Z may have been inaccurate in the first place.

Anyways, I have the Vcore showing up as 1.358 in the BIOS. I may overclock it higher in the future, seems pretty easy to go over 4 GHz.

Interesting. FYI, I have the Z68P-DS3, and use Core Temp 1.0 to monitor vcore. When my 2500 (non K) turbo's to 4.0, the values fluctuate between 1.22 and 1.25. When running Prime95 large FFT's, though, Core Temp reports the voltage as 1.32 @ 3.7 for all cores, which seems a bit high, even with the offset set to +0.000 (LLC enabled). Has latest BIOS (F7). Not sure what's going on with this board.
