OC Tools for Linux - Overclock.net

Sir Humpsalot · 10-17-07

Ok, so we have dangerousHobo's fantastic cpu-z like tool PerlMon for checking CPU speed and such.

We also have MemTest

Now, what can we use with linux for stress/load-testing the CPU?

Any other useful programs out there?

Live CD

stresslinux - stresslinux is a minimal linux distribution running from a bootable cdrom, usb drive, or via PXE

Monitoring

lm sensors - monitor fans, voltages, and temps

hddtemp - monitor hdd temps

smartmontools - monitor hdd's using the SMART system built into the hard drive

Benchmark Suites

freebench - free memory, integer, and floating point benchmark

lmbench - portable benchmark suite

ltp - the Linux Test Project benchmark suite

nbench - BYTE Magazine's BYTEmark tests memory, integer, and floating point performance

xfbsuite - benchmark suite for X

CPU tests

Kernel compile
You can benchmark your system by simply timing you kernel compile. As long as you use the same config file, this will give you a pretty good idea of how you're computer is scaling as you overclock. It will also give you an idea of stability because an unstable system will cause compilation errors. You will need to keep your own log of compile times for reference. This can be used to compare separate systems as long as the same architecture and config file are used. To time your source compile, simply enter the kernel source directory (i.e. /usr/src/linux/) and type:
Code:
# time make
when it is done, it will display the overall time it took to complete, which you can then throw in to a text document or spreadsheet to graph, if you'd like.
CPUBurn - stress the cpu

gamut - loopable benchmark app (formerly Sstress)
