Hello guys, I would like to ask for advice because I have the Z68X-UD3H-B3(REV1.3) M/B with the Intel core i5 2500k cpu and 8GBs of corsair vengeance ram (2X4GB). I recently installed the latest bios for my M/B which is the U1L and for some reason when I go to the advanced cpu feauters and change the turbo core ratio to all for cores from ayto to 40 and i press F10 to save and reboot the pc shuts down and restors the default settings. Also I use XMP and I set performance enhance to extreme. Could you please help me?
