I too was having problems with motherboard monitor, so I found another one called Hardware Monitor Pro that seems to be working better for me. I wasn't sure I could trust the readings, so I changed by cpu and voltage back to normal, ran some tests, and it seemed to be measuring temps about where I would expect them to be, then upped the speed and voltage little by little, and temps rose correspondingly. So, while I obviously can't be certain of how accurate it is, this program is giving me the most repeatable results of any I have tried on my system--Soyo 6BA+IV and Celeron 2 600@1035. YMMV.
