According to all the documentation that I am reading, I am setting the "CURRENT level in AMPs" limit to the cpu at 77 amps.
( I thought watts as well, but everything says amps. I can limit the turboboost limit in watts, but CPU is amps.)
The Intel extreme tuning utility (in addition to the Asrock bios), lets me control the turboboost in watts and CPU limit amps , and gives nice real time graphs, and allows real time tuning changes as well.
But still want to know if 80C is a reasonable peak Temp.
