Which voltage reading is correct?

[kmax86]

Coretemp says 1.336 - 1.382v
CPUz says 1.240 - 1.256v

the only thing i changed from the bios is the xmp profile of ram
everything else is in stock in the p8z68-v and 2500k

the difference is quite huge so I dont want to start changing the voltages until I know what software should I read

thanks

bios says offset +

Im having problems with the asus monitoring tool it keeps crashing / not responding when used along side with IBT.

sorry the voltages in my first post have intel burn test running.
