I also am not an expert on AMD chips, but ~65C seems acceptable for an |
| 42 |
upper-level temperature to me. |
| 43 |
|
| 44 |
Unfortunately, the AMD documentation |
| 45 |
(http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_739_7203,00.html) |
| 46 |
doesn't really specify what the throttle and shutdown temperatures are |
| 47 |
of the processor. They just say that the case temperature should not |
| 48 |
exceed 42C, and that Tcase_max is 70C. I am reading that as meaning 70C |
| 49 |
is the upper design limit for the processor. |

What does bother me, as Glen alluded to, is that you are not seeing a |
| 52 |
drop/rise in temperature with load. That indicates that maybe your |
| 53 |
kernel configuration isn't correct for the Athlon64. Double check your |
| 54 |
kernel configuration, and make sure you have support for the Athlon64 in |
| 55 |
your kernel. You might also try enabling "CPU Frequency scaling" with |
| 56 |
the "ondemand" governor and the Athlon64 driver. |
| 57 |
|
| 58 |
You could also post the output of dmesg. |

FYI, the pentium-m in my laptop idles at around 60C, but will easily |
| 61 |
reach 85C under full load. Fortunately, it doesn't throttle until 95C, |
| 62 |
and doesn't shutoff until ~105C. |
