Product Description:

This small command-line utility thoroughly checks available memory under OS X. Memtest is licensed under the Gnu Public License and is distributed with source code. This program was originally authored by Charles Cazabon for Linux platforms and the MacOS X port is maintained and enhanced by Tony Scaminaci.

What's new in this version:

Version 4.21 adds
  • A quick option to shorten the total run time. This feature is still under development so the improvement is only slightly better at this time. Future versions of memtest will improve performance significantly when using the quick option.
  • When the user chooses to write out a log file to disk, memtest now reports the full unix path in the header messages. This should resolve confusion over where the log has been written.
Memtest OS X is distributed as a universal binary that runs on all PPC and Intel-based Macs and can be downloaded for a minimal fee of US $1.39.

  • Mac OS X 10.4 Intel

Memtest Usage TipHow to legally get memtest without paying for the download - Version: 4.21, 1/6/2008 03:58PM PST

Rember uses memtest at its core. However, Rember isn't able to test any memory that is being eaten by the OS, so, if you want to really test your RAM, you should:

1) install Rember

2) Boot into single-user mode:

hold command-S on boot, then:

/sbin/fsck -fy

/sbin/mount -uw /

3) Once you have the hard drive mounted, run the memtest executable buried in Rember. If you installed Rember to /Applcation/Utilities the path would be:

/Applications/Utilities/Rember.app/Contents/Resources/memtest

For memtest switches look here:

It's one thing to charge for the software, but as I understand it, this is open source software that he's modified, so any changes he makes to it are required to me made open source as well. By putting it behind a locked door (i.e. you don't get the source until you pay for it) he's breaking the license, last I checked.

The developer could charge a higher fee, and automatically email the latest revision the way SoftRAID does. That should address his concerns and not be a hassle for users wanting the latest version.
