It sorted out the coincidence theory. I agree with you that the
overclocked cpu was more fragile. I spotted a week ago that the cpu was
not as robust as at the beginning.While inspecting the capabilities of
the northbridge I ran stability testings for about ~30hrs with
northbridge voltages at around 1.4V (1.3V is stock). After that the
system was no longer stable at 2.8GHz with 1.3125V (1.3V stock). Going
back to 2.7GHz fixed the stability issues. I ran this for at least a
days without any problems till it froze. It was just a coincidence that
i used lm-sensors and not typical windows monitoring tools.

Exactly in oposite to the user of the DFI Lanparty board with the nvidia
chipset i get no hangups when i load the it87 module manual without
parameters excluding 0x2e.

Other already tried to flash the dfi bios on the sapphire board and i
also used it for weeks because the bios the board was shipped with had
all type of issues.
So I switched to the latest stable DFI bios and attached a dmidecode
dump here.
I also tried i2cdump at 0x4e and 0x6e.
Same results as with the sapphire bios. Again the 0x6e dump stopped at
0x9e and outputs only XX till i reboot, a reload of the i2c-piix4 module
does not help here.
