Having 1.232v idle is stable with Orthos but with Linpack not quite.

Note: It is C0 stepping
I was missing some of the screen shots when I first viewed you post. I now see that some of your CoreTemps show a 1.1625 VID... I don't think that 1.248v is too much but those temps... that 10 hour orthos run showed peak temps as high as 82C/84C... your chip seems to run pretty hot.
I guess you have tried to reseat/remount your cpu/cooler?
