Yes some people require up to 1.6V, even my XMP profile puts it to around 1.5V for 2GHz. On the Corsair forums they say it can take between 1.5-1.6V. I personally don't like taking it above 1.35V.

Tbh QPI is such a tricky voltage as it is needed for both RAM and the CPU - such a pain! Overclocking was so much easier with the 775 socket .
