MemTest86 is the original, free, stand alone memory testing software for x86 computers. MemTest86 boots from a USB flash drive or CD and tests the RAM in your computer for faults using a series of comprehensive algorithms and test patterns.

Main Features:

The latest version of MemTest86 supports all the current technologies, including

13 different RAM testing algorithms
DDR4 RAM (and DDR2 & DDR3) support
XMP - high performance memory profiles
UEFI - The new graphical standard for BIOS
64bit - From version 5, MemTest86 is native 64bit code
ECC RAM - support for error-correcting code RAM
Secure boot - With MemTest86 being code signed by Microsoft
Graphical interface, mouse support and logging of results to disk
Foreign language support (Chinese, German & more)
Self booting off USB or CD, without needing DOS, Linux nor Windows
Dual booting - Will boot to V4 in BIOS and V6 in UEFI from a single flash drive

MemTest86 supports booting from both the newer UEFI platform and the traditional BIOS. When booting from UEFI, MemTest86 has access to additional services not available in BIOS including:

Native 64-bit support
No longer requires the use of the PAE workaround to access more than 4GB of memory. (PAE = Physical Address Extension)
Mouse support, where supported by the underlying UEFI system. On older systems a keyboard is still required.
Improved USB keyboard support. The keyboard now works on systems that fail to emulate IO Port 64/60 correctly. So Mac USB keyboards are now supported.
Improved multi-threading support, where supported by the underlying UEFI system.
Reporting of detailed RAM SPD information. Timings, clock speeds, vendor names and much more.
Support to writing to the USB drive that MemTest86 is running from for logging and report generation. In all prior MemTest86 releases, there was no disk support.
Use of GPT. (GUID Partition Table)
ECC RAM support (limited hardware support, ongoing development)
Detection of ECC support in both the RAM and memory controller
Polling for ECC errors
Injection of ECC errors for test purposes. (limited hardware only)
Support for DDR4 RAM (and associated hardware), including retrieval and reporting of DDR4-specific SPD details. This includes DDR4 RAM that support Intel XMP 2.0 DDR4 RAM timings
Option to disable CPU caching for all tests
Having a configuration file to allow settings to be pre-defined without the need for keyboard input. This can help with automation.
Support for Secure Boot.
Speed improvements of between 10% and 30%+. Especially for tests, #5, #8 & #9. This is the result more moving to native 64bit code, removing the PAE paging hack, switching compilers and using faster random number generation algorithms.
Addition of 2 new memory tests to take advantage of 64bit data and SIMD instructions.

New Features:

New config file parameter REPORTNUMERRS for specifying the maximum number of errors to include in the report
Language support for Spanish
RAM details obtained from SMBIOS are now displayed if SPD information cannot be accessed
