memtest86+ 5.01-3ubuntu2 (i386 binary) in ubuntu cosmic

 Memtest86+ scans your RAM for errors.
 .
 This tester runs independently of any OS - it is run at computer
 boot-up, so that it can test *all* of your memory. You may want to
 look at `memtester', which allows to test your memory within Linux,
 but this one won't be able to test your whole RAM.
 .
 It can output a list of bad RAM regions usable by the BadRAM kernel
 patch, so that you can still use your old RAM with one or two bad bits.
 .
 Memtest86+ is based on memtest86 3.0, and adds support for recent
 hardware, as well as a number of general-purpose improvements,
 including many patches to memtest86 available from various sources.
 .
 Both memtest86 and memtest86+ are being worked on in parallel.
