It is the very first value reported (Top of the list) in the Hardware Monitoring BIOS screen.

I ran this test for about 15 minutes. The system voltages changed slightly...no more than 5 hundredths up or down: that looks like a very stable power supply. System temperatures did go up: it pushed CPU temp up about 5 degrees Celsius, from ~42 to ~47, but never reached 50 degrees Celsius. Systemgraph shows CPU MHz ramped up to full speed: this system can use the "userspace" governor with ~200 MHz steps starting at ~200 MHz and topping out at ~1600 MHz. > > -- > Jean Delvare > http://khali.linux-fr.org/wishlist.html > _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
