Memtest86 is a free utility application that allows PC users any model of x86 CPU to run comprehensive tests regarding the stability of your RAM memory. This includes a wide array of tests that will determine if your RAM is causing or will potentially be future cause for system instabilities, crashes, corrupted data, and a wide array of unexplained behavior.

System RAM memory is integral for the proper functioning of your OS and handling of your data, and confirming that it is at fault (or ruling it out) can save you many worries and help you with troubleshooting errors on your PC.

Itis built from the ground up to run independently of your OS. To run it, you need to copy it to a self-booting USB stick, and then restart your PC and boot this mini-app from your USB. To make this process easier, It comes with a built-in image USB tool. In addition to USB sticks, Memtest86 (which can handle older BIOS and not modern UEFI BIOS) can also be booted from CD/DVD or even floppy discs.

Features and Highlights
  • Self-booting from USB flash stick
  • A comprehensive suite of 13 RAM testing algorithms, all targeted to check your RAM for potential faults.
  • Modern graphics interface, suitable for both novices and professionals.
  • Support for all current RAM versions - DDR2, DDR3, and DDR4.
  • Ability to recognize XMP profiles.
  • Support for ECC RAM, error-correcting code RAM.
  • Full support for UEFI, the latest visual UI BIOS.
  • Since version 5, It has become a native x64 app.
  • Memtest86 is a Microsoft registered app that can handle SecureBoot feature of modern BIOS
  • Expanding support for foreign languages.
  • Support for a wide array of enthusiast networking features, including Network Boot (PXE), full test automation, exporting of test results to file, and more.
Differences between BIOS and UEFI versions

It is very important to note that PC users who have older motherboards with BIOS need to download a free version of the program. Users with newer motherboards that feature the UEFI interface need to download newer and feature full the app. The tool is safe & secure, tested to be virus-free. All of its files are in their original form. This benchmark tool is great and very useful.
 
Differences between FREE and PREMIUM versions

Have no fear, because the free version of Mem test 86 packs in incredible functionality that can help both novices and seasoned veterans of the PC repair in testing RAM memory. Premium version of Memtest 86 expands on the already great functionality of the base free version and adds several advanced features that are focused on more premium types of RAM memory (ECC RAM), networking features, automation, and data collection.
