Memtestx86.

If you have 4GB or more memory, make sure you are testing with memtestx86 3.5a or higher.

just about any live_cd from any 'nix distro

- will have a program called memtest86+
or something similar, to that, on the boot menu, when you boot from that cd.

just run that for an hour, & see if any errors show up ( usually red in colour)

I would recommend to always use the latest version. I also think that one hour for an production machine is far to less, and it is totally dependent on the amount of memory. On my 8GB workstation you wouldn't test the RAM completely in one hour. I wouldn't even count the necessary runtime in hours but in passes. For a important production machine I would recommend to run at least 10 passes, for a home machine I would recommend at least 3 passes.
