Hi, I wrote a while ago because of problems with the w83l785ts. I think the problem is solved since I swapped the order in which the modules are loaded: First i2c-nforce2, then w83l785ts, and then asb100. I also updated my BIOS from 1007 to 1010 but the problem was gone before that. Thank you Johannes H?bner Jean Delvare wrote: >>I have an Asus A7N8X-X mainboard with the asb100 (bach) and the >>w83l785ts chip. Latter one reads the internal CPU-temp-diode.
