Memtest86+ v6 is a unified, free, open-source memory testing tool,
released under GNU GPL v2.0. The new v6 code base (originally called PCMemTest) was
provided by Martin Whitaker, based on Memtest86+ v5, developed by Sam Demeulemeester.
Both are now working on Memtest86+.
Memtest86+ is unrelated to 'Memtest86', a closed-source `Freemium` software
released in 2013 by PassMark Software Pty Ltd.
