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
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.
