This program, as well as memtest86+, are the best memory (RAM) test programs you can find. It implements the most important memory testing algorithms (there are more advanced algorithms out there, but those would take much more time and are suited to specific types of memory only), so you get a quite good coverage of memory faults. For some time this version was not supported, but recently Passmark took up support so it should be up-to-date again. Use either this (I didn't have any problem of burning this to a bootable CD, although nowadays I rather put this to a bootable USB disk), or memtest86+, and you cannot go wrong.

I use this for all memory tests and basically, it detects when ram is bad and is very thorough. It's easy to use, free, and is trusted for results by many techs. I feel it's a must have.

I recently bought 2 new sticks of ram for a home pc that I wanted to run a test on.
I tried unsuccessfully to use memtest86 as I was unable to burn iso image to disk. After researching I found another version, memtest86+, based on the original mtest86, and was able to use the guide to burn a bootable disk and run the program. I let it run for a couple of hours in which it stringently ran 10 different tests, gave diagnostics and thankfully found no errors with the ram.
Review details
I had built a new high-end gaming/development PC and everything was running fine. Two weeks later I was having all sorts of issues booting up and running applications. It wasn't until I used this utility to check the 2 GB of RAM I had placed in the box that I found the issue. A bad memory module from a cheap supplier I had chosen. You get what you pay for, right. It's the best memory diagnostic I've come across so far.
