It is possible to change on a warranty ?
There is no point, the CPU is not faulty, it is just that the factory settings are odd. My 960T is exactly the same.
You've already have the answer as you have discovered that the default 960T p-states and corresponding CPU VID and frequencies are:
B0 1.475V 3400MHz (Turbo)
P0 1.325V 3000MHz
P1 1.325V 2300MHz
P2 1.325V 16000MHz
P3 1.325V 800MHz
So, if your BIOS CPU voltage is on AUTO and Turbo is also on then the CPU voltage will be 1.475V, which is unnecessarily high.
If you turn Turbo off in your BIOS and leave CPU voltage on auto it should default to 1.325V. But your m/board design/BIOS may even leave it a little higher, say 1.35V.
Left like this, CnQ works as the CPU freq varies with load ,but the CPU voltage range is as you know is 1.325v - 1.475v.
The only options I know of to lower these voltages are:
(a) undervolt your CPU by manually setting the CPU voltage in your BIOS
(b) use the AMD overdrive program
(c) use the k10stat program in Windows, or k10ctl in Linux on its own, or combined with (a)
Unfortunately, options (a) and (b) will still leave you with states p0-p3 running at the same voltage.
The most flexible solution is (c).
The 960T is capable of running at 800Mhz with a voltage of just 0.8v.
Finding the lowest stable voltages for your own 960T at for each p-state is a case of trial and error. You could use data from AMD's desktop processor power and thermal data sheet as a guide. There is no data for the 960T itself, but the 1045T is pretty close in specification.
