I have the same cpu. For some reason my motherboard by default automatically
overclocks all my voltages upwards. So I end up for example with a 1.69V
Vcore. Almost 1.7. This is with deafult bios settings. So basically, depends
on the motherboard you use, it will vary. If you get automatic voltage
increase and everthing goes well and no heat problems, don't worry and enjoy
your pc.
