I am trying to overclock my machine. All the changes are made on the BIOS level, but then one needs to check all the temperatures, voltages, etc and test the stability of the overclock. Most tutorials (if not all) are written for Windows. What would be Linux alternatives for:

CPU-Z: to display all the CPU information, including Core Speed, Core Voltage, current multiplier, etc.

HWMonitor: check fan speed and core temperatures

Prime95: stress testing with results validation

Also I would like to be able to monitor VTT and NB voltages (see a short explanation of all voltages) for Intel processors (I have a Q9450) - I haven't actually found a Windows program that does it yet.

For CPU-Z I can't really say (/proc/cpuinfo doesn't give core speed, multiplier etc...).

For hardware monitoring the sensors command (part of the lm_sensors package) should work; it doesn't have a GUI per se, however.

Finally, the stresslinux distro has many stress-testing utilities.

For stress testing I recommend using SETI@home for two reasons:

  1. Great stress testing
  2. Your PC helps science

For changing voltages, use linux-PHC (CLI)

For monitoring temperatures, use lm-sensors (CLI)

For Ubuntu/Debian (as root):

apt-get install lm-sensors
yes | sensors-detect
/etc/init.d/module-init-tools start

Then type:


It should show you temperatures.
