Memtest86+: Comprehensive Memory Testing

Free, open source memory testing utility for x86 computers, detecting RAM errors and faults to help troubleshoot faulty memory issues

What is Memtest86+?

Memtest86+ is a free, open source memory testing utility for x86 computers. It is one of the most popular tools used for testing RAM, as it comprehensively tests all memory and can detect a wide range of errors and faults that may be causing issues.

When launched, Memtest86+ bypass the operating system and directly tests RAM chips and modules. It writes test patterns to all memory locations, reads back the data, and compares it for errors. This allows it to detect failures in RAM that may manifest as random crashes or boot failures in operating systems.

Memtest86+ has a simple, text-based user interface that displays ongoing tests and any errors encountered. It provides details on the type of error, the location, and sometimes suggestions for resolving the issues. The tool is useful for troubleshooting mysterious crashes or boot problems by testing the RAM and eliminating any faults.

Overall, Memtest86+ is regarded as one of the best free memory testers available. It can run for days continuously testing RAM without supervision. The utility runs independently from operating systems like Windows, Linux and OS X, making it useful for any x86 computer.
