I have my vcore set to 1.375v in bios and CPU-z reads 1.328v. As a general rule when Intel states 1.375v is the max safe CPU voltage for the Core I7 920 do they mean settings in bios or what programs like CPU-z read? Also do you think 1.375v for vcore is to much for 24/7? My max core temps are 73,72,70,68 when running the prime95 small FFT test. I manually set all other voltages to stock settings except QPI/VTT which I set to 1.220v to get this 920 to 4.2Ghz.
