i currently have my intel e6400 running at 8*380=3040 MHz on my gigabyte EP45-UD3P with the latest bios. my concern is that my system is runnin below normal voltage, regular voltage is 1.325 and is currently set to 1.296
should i be worry?
nope. Do not worry at all. Under load you get what is called V-droop. This, while a pain for some higher overclocks will not hurt the system(Intel in fact says it should be there). As long as its stable, do not worry.
