我用watch -n 1 "sensors"監視cpu溫度
一邊開四個核下去轉x264
然後....
cpu一路從四十幾度衝到七十幾度....囧
顛峰時期四顆核溫度大約 79,72,72,68...之類的...
但是就一直不當掉XD
然後最後終於當掉了...
死前瞬間顯示溫度是 74,67,72,64
....所以這樣是不是幾乎可以用熱當來結案了@@
我現在有在bios設定 60度C時風扇至少轉速要到62%了QQ
..感謝大家的相助QQ
對於熱當跑來linux板亂我非常愧疚XD
只好煞有其事的做個這次debug之旅的總結QQ
好假裝自己真的沒走錯板XD
1.
watch -n 1 "xxxx" 可以每秒執行一次xxxx
就不用自己寫bash loop了XD
2.
magic sysrq key很酷
可以在系統失去回應時手動重開機之類
http://en.wikipedia.org/wiki/Magic_SysRq_key
常見用法是 alt+sysrq+ [r,e,i,s,u,b] (依序)
3.
memtest86+ 可以用來測試ram有沒有問題...
4.
http://linux.vbird.org/linux_basic/0610hardware.php#hw_pre_lm
鳥哥有說
裝了lm_sensors之後
可以用sensors-detect偵測你有哪些溫度sensor
從此之後
就可以用sensors這個指令查cpu溫度 還有其他資訊
gnome 3 有一個extension好像就是用lm_sensors來偵測cpu溫度
fedora下可以yum install gnome-shell-extension-cpu-temperature
之後螢幕上方的那條工具列就會顯示cpu溫度了
還蠻方便的
...沒哏了QQ
謝謝大家!!!
