...if some NHM owners can post somes screens of this beta (Read only version): CPU-Tweaker-beta1.zip
I need it before continuing writing...

Note that it's a new version wich support only NHM and K10 CPU (with integrated Memory Controller).
The interface is the same for both CPU, and I use WinRing0 driver now (unstead tvicport in memset).

I keep memset for chipsets with integrated memory controller (P35, P45...) and athlon64.

Thank for the report...
