memtest86+

memtest86+ is an open source and totally free command-line software, an enhanced version of the original memtest86 memory tester application created by Chris Brady.

The memtest86+ project aims to be as reliable as the original, it has been patched to work on AMD64 platforms, and it can also properly detects all current motherboard chipsets and CPUs.

The software supports ECC polling for AMD64, E7205, and i875P, and displays some useful settings for the most popular chipsets, including Intel, nVidia, VIA, and SiS, FSB & Memory frequency, memory timings, as well as PAT status.
