A comprehensive suite of 13 RAM testing algorithms, all targeted to check your RAM for potential faults.


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. To make this process easier, It comes with a built-in image USB tool. 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.

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. 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. The download links for the V4 downloads are still provided for those that prefer to work with the V4 bootable images.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. In order to run MemTest86, PCs with legacy BIOS platform must use the older V4 release of MemTest86. However, you must use either Windows, Linux or Mac to create a bootable USB drive.įor information on creating a boot disk in Linux/Mac, visit the Technical Information pageĪs MemTest86 V10.5 supports only the newer UEFI platform, older PCs without UEFI support would be unable to boot MemTest86.

The version of Windows, Linux, or Mac being used is irrelevant for execution.
