Memtest86 is great!

I'd like to second the comments made here about Memtest86. It is a fantastic tool (although I recommend the "plus" edition, Memtest86+).

This tool has literally saved our bacon dozens of times, not to mention prevented us from pulling out hair on our heads by the fistful. Big giant kudos to the developers who have invested their hard work into this fantastic app!

memtest86+ is also available, its based on memtest86 3.0, supports newer hardware, and includes various improvements.

In addition, there is memtester, which runs within linux but it cannot test the whole RAM amount.

It's a memory testing and system stress testing utility designed for high performance supercomputer beowulf cluster nodes. It also works on your grandmother's machine, provided its 64bit. It's Free Software, and has provoked instabilities that memtest simply didn't reveal. Read about and download the ISO or netboot package from
