Overclockix is a decade-old Linux distribution originally spawned from Knoppix that was formed around interests in hardware tuning, stress-testing, and of -- course -- overclocking. Overclockix .017 was released today and this release is its first to be based upon the recently released Debian Wheezy. Prior to the .017 release was a .016 release in February as its first release since early 2012. Overclockix was resurrected in 2011 after the distribution fell apart in 2005, two years after its original debut.
The Wheezy-based Overclockix .017 is still designed around its original purposes and includes programs like MPrime and Y-Cruncher for stress-testing. Sadly, that's about it for its specializations these days. You can get pretty much the same stress/load testing effect by choosing your favorite Linux distribution's LiveCD and then simply installing the Phoronix Test Suite and firing up your favorite subsystem's workload in a fully automated and streamlined manner.
