2500k

so tonight i was bored and decided to play with my overclock a bit....i figured i would get the voltage back under control and down to about the 1.35V mark. so at the 1.35V mark i was able to get up to 4.2GHz stable. under load the voltage in cpuZ drops down to 1.32 - 1.33 volts. on idle it bounces between 1.35 - 1.36 volts. loosing the loto sux

Well first of all I'l just have to say you've been quite unlucky with your CPU cuz 1,35V for 4,2GHz on a 2500K just isn't very good at all =/

Second, it's completely normal for the CPU voltage to drop when it's under load. It's called Load Line Calibration or LLC and is supposed to bring down power usage and suppress voltage spikes when the CPU goes from load to an idle state.

I saw a thread describing in good detail what LLC is. I'l try to look it up

looks like you havent won the silicon lottery

sort the LLC and it shouldnt bounce around so much

ive played with the LLC a fair bit....got it set to 8 right now.....if i set it to 10 it goes all a mess.....cant get the idle voltage below 1.48, thats with the voltage in the bios set to 1.18, and under load it drops to 1.2 and freezes, so set to 8 with the bios set to 1.3, gives me 1.35 - 1.38 in windows, drops to 1.32-1.33. this is with a new AX760i PSU installed, so i guess i just want to blame the motherboard now for the voltage spikes......gigabyte Z68X UD3 board.....should of listened to my buddy when he told me to get the UD5 lol if i had my time back i would have
