Overclocking tools in Linux

Question

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.

google search the highlighted names for more infomation

CPU-Z alternatives (CPU information)

CPU-G (Simple)
i-nex (Advanced)

installation tutorial

HWMonitor alternatives (temperatures & fans speeds)

Psensor (Easy)
Xsensors (Simple) [GUI for lm-sensors] use [watch -n 1 -d sensors]

for Desktop integration use gatotray or the [Panel applet] sensors

Prime95 alternatives (Stress testing)

MPrime (command line) [linux version of Prime95]
system stability tester (Easy) [CPU]
unigine benchmarks (Awesomely Easy) [GPU]
Phoronix Test Suite |Stress-run| (expert) [all hardware]
Breakin stress-test (Expert) [bootable OS] [all hardware]

System & hardware information

HardInfo (easy) [System profiler and benchmark]
kinfocenter (Simple)
sysinfo (Basic)
lshw-gtk (Advanced) or [sudo lshw -short]

install with sudo apt-get install (name here)

terminal commands & utilities

stress testing stress & stress-ng cpuburn stressapptest

System information commands

sudo dmidecode --type processor [ for help google dmidecode Details]

sudo cpufreq-info

cat /proc/cpuinfo

inxi -xSCs

hwinfo --short

you can help by adding appropriate links to numbered & highlight names, because i can't — Vencen, Feb 27 '17 at 04:52

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

Great stress testing
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:

sensors

It should show you temperatures.

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.

stresslinux makes use of some utitlities available on the net like: stress, cpuburn, hddtemp, lm_sensors ...

stresslinux is dedicated to users who want to test their system(s) entirely on high load and monitoring the health.

Stresslinux is for people (system builders, overclockers) who want to test their hardware under high load and monitor stability and thermal environment.
