I checked the voltage by setting the clock speed manually and it gets at least closer. -Snipp- > > Your CPU cooling seems insufficient. A 56°C difference between idle and > load is very, very much.

If I just up the clock speed, it doesn't get hot. -Snipp- > When you have come up with a "final" configuration file, please send it > over, and I'll put it on the wiki. > Ok, it's attached to the mail. It remained nearly unchanged, except for the compute lines and the limits you suggested. The two non-trivial compute lines are taken from comparison of values (BIOS<->sensors) and then searching the nearest simple voltage divider that would work. The values are pure guesses! Thank you again for your help!
