hi i have ip35 pro xe with a e8500 and thermalright 120 extreme if i use cpu-z it changes the cpu mhz by stepping from 3054x9 to 2043x6 as you look at the panel of cpu-z is this normal and why ? also if i use core temp it tells me core 0= 19 degrees core 1=31 why is this ? also u-guru only gives a reading for 1 core of the chip . iv checked the bios and the system only shows 1 temp which is well within parameters but why the big difference , ihavent even changed anything ie overclocked as yet as I'm looking advise on that also
