These reading were shown by everest ultimate edition,,, i have recently installed an i5-2500k, the PSU is cooler master gx550 watt,, are the voltage readings correct ,, i dnt have gud knowledge about voltages but the CPU is shown underclocked to 1.5ghz most of the time nnd it keeps fluctuating,,,, so i go for a warranty replacement as the PSU is in 5 year warranty!!
