I'm sorry that it took so long, here is the Update:

Unpack the file and copy it to the subdir "inc/libs" (replace old file).
I hope it is correct (should be).

Check if you get Values between 1.000 Volts (lowest Frequency) and 1.250 Volts (highest Frequency)
with default VIDs.

Hey! Thank you so much!! It seems to work now. :D :D :D
The default VIDs differ from the values you wrote.
The highest one is 1.40625V and the lowest one is 1.0625V.

Hmmh, okay.

The formula should calculate correctly with the given values.
I rather think the phc-patches provide different values.

Hmm, hard to find the reason since I do not own a newer Core2Duo like you.

But you can provide me with values so I can investigate if you like.
Until I found the reason I recommend you not to set up values to the phc-interface (you can keep the module if you don't want to replace it with the original one).

And you could do the following:
Set your frequencies manually (using the gnome CPU Frequency Scaling Monitor for example).
Begin with the lowest and step to the highest. For each step use the read_msr tool and send me at least the lines "Current VID" and "Current FID".

Thank you.

Hey, thank you! But don´t put too much time in it. I´m sure you have better things to do.... ;)
It´s not that hasty.
Here are the VIDs and FIDs for the default values:

Code: Select all

@ 800 MHz :  cpu0 and cpu1 : current VID:  19
                             current FID: 136
           
@ 1,2 GHz :  cpu0 and cpu1 : current VID:  23
                             current FID:   6
             
@ 1,6 GHz :  cpu0 and cpu1 : current VID:  28
                             current FID:   8

@ 2,1 GHz :  cpu0 and cpu1 : current VID:  34
                             current FID:  74
            
@ 2,101 GHz: cpu0 and cpu1 : current VID:  41
                             current FID:  75
