Hi :)
I'm running Ubuntu 10.04 on a machine with an ASRock 775Twins-HDTV motherboard and an Intel Pentium D CPU. When my cpu gets too hot (above 70°C I think, not too sure) I get these messages in my /var/log/syslog:
"Core temperature above threshold, cpu clock throttled" and
"Core temperature/speed normal" some seconds later.
The problem is: the more often this happens, the slower my machine gets, for whatever reason... So I tried to avoid this by disabling any thermal throttling (for CPU and for mobo) in the bios settings. Gave no change. Installed mcelog, when I run "sudo mcelog" I get more information:

The problem is no longer that relevant since I cleaned my cpu cooler and built in a better fan so that my machine nearly never reaches critical temperatures. But it still puzzles me... So:
- Why is it continiously getting slower each time it throttles and gets back to normal speed?
- How can I disable thermal throttling if not in bios??? At least I'd like to manually set the threshold temperature...
Any HW specialists out there that could help me with this?
