What power supply are you using? A cheap PSU might be your answer.
Well the PSU I am using is not a cheap one altough it is not as good as antec.
It is 500W power-supply by L&C and in india considered GOOD (after antec and cooler masters) and people who can't afford antec buy this powersupply
Surprisingly at load the voltage seems to not fluctuate.
What is the ideal voltage which needs to be supplied to core 2 duo E6300?
