Memtest86 Free v10.5

Industry standard for memory diagnostics.

• MemTest86 is the original, free, stand-alone memory testing software for x86 and ARM computers.
• Boots from USB flash drives to test the RAM in your computer for faults.
• Utilizing algorithms that have been in development for over 20 years.
• Industry standard since 1994.

• 13 different RAM testing algorithms - including row hammer fault detection
• All RAM types supported (DDR2, DDR3, DDR4, DDR5, SODIMM, XMP, ECC)
• Self-booting off USB without needing DOS, Linux nor Windows
• Optimized for UEFI-based x86/ARM systems
• Native 64-bit code (since version 5)
• Secure Boot verified – Code signed by Microsoft
• Graphical interface with mouse input
• Save logs and create customizable HTML reports
• Full test automation via configuration file
• Support for memory blacklisting in Windows (badmemorylist) and Linux (BADRAM)
• Multi-language support (Chinese, German, Russian, Spanish and more)

• IMPORTANT: MemTest86 V10.2 images support only UEFI boot. On machines that don't support UEFI, MemTest86 will not boot. Please download the older V4 BIOS release of MemTest86 instead.

Changed units from MHz to MT/s when referring to DRAM transfer rate (typically double the clock speed for DDR RAM)
Reduced the execution time of hammer test by increase minimum segment size per thread from 128MB to 512MB
Reduced the execution time of hammer test by reducing the maximum number of memory segments to hammer from 64 to 32
Fixed crash when running the Block Test RAM benchmark
Added ECC support for Intel Raptor Lake chipsets
Added DIMM temperature support for Intel Broxton chipsets
Extended DIMM decoding support for additional Alder Lake and Raptor Lake chipset variants
Fixed disabling of hyperthreads for CPUs with hybrid cores
