I have an i5-3570K installed into a Gigabyte Z77X-D3H board.
I've manged to get a decent stable overclock with this board simply by cranking up the multiplier to 44 and leaving the VCore on Auto. Now I know that leaving VCore on Auto is not recommended but at this current setting CPU-Z is showing the voltage at 1.29 which is fine I believe for this processor.
I can knock the multiplier down one to 43 and the voltage in CPU-Z drops to 1.21 or something similar. If I knock it up one to 45 though the voltage cranks right up to 1.41 in CPU-Z which of course is a no-no so I immediately reboot the PC and set it back.
My question is to why the board takes the voltage in such high steps for that 100MHz increase. What would I need to do?
I'm happy really with 4.4GHz as it's a free 1.0GHz over stock for basically no effort.
Temps are fine with my Seidon 120M water cooler in Core Temp not going above 70-75 under load at 4.4GHz.
I did try to go at 4.5GHz with the VCore fixed at 1.31V but it wasn't stable and I didn't want to push much past 1.3V.
