The VID value is the amount of voltage the CPU is requesting. It is not the same as the actual voltage that the CPU is running at. CPU-Z reports actual voltage.

The adjustable Turbo Ratio Limits works great on the previous generation Core i7/i5 Extreme and K series CPUs but I haven't heard any reports of this working correctly on the new Sandy Bridge CPUs. It's possible that the bios has locked this feature so you can not go beyond the multiplier that you originally booted up with. What motherboard are you using? Does it come with any software that lets you raise the turbo multipliers when in Windows?

Sandy Bridge CPUs have a variety of lock bits so motherboard manufacturers can disable a lot of features in the bios which prevents any Windows software from adjusting things. The Intel public documentation that I use doesn't fully explain things compared to the docs that the bios guys get at Asus and Gigabyte, etc. Hopefully I get this figured out someday if it is still possible to increase the multis.
