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. > Looks a lot like that older bug report I mentioned where probing > address 0x2e rebooted the machine.

Can you provide the dmidecode information for the > DFI board / BIOS? > 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. -------------- next part -------------- # dmidecode 2.9 SMBIOS 2.5 present. 54 structures occupying 2274 bytes.
