Note: The Free version will still work on higher core count CPUs, but will only use the first 16 cores. MemTest86 support up to 16 cores in the Free version and 512 for the Pro version. These are tests using the CPU's SSE/Neon instructions to read and write 64bit and 128bits of data at a time from the RAM. Currently only available for selected hardware configurations. DIMM and Chip decoding allows the a memory address with an error to be decoded to a physical hardware location (memory slot and silicon chip). The following chipsets are currently supported: ^ĥ. Otherwise, MemTest86 shall report the configured memory settings stored in the SMBIOS (which may be inaccurate). MemTest86 attempts to retrieve the memory settings configured in the BIOS, for a limited number of supported chipsets. The keyboard now works on systems that fail to emulate IO Port 64/60 correctly. Most systems implement Microsoft Secure Boot, which only allows applications/drivers signed with a Microsoft signature to load properly.

Secure Boot is a feature in UEFI that only allows drivers and applications that are signed with an acceptable signature to run on the system. However, is not recommended or supported as USB boot is preferable. While booting from a CD is still technically possible, the CD/DVD ISO Image remains available for download.

If you are looking for old BIOS, floppy disk or CD support, we recommend using MemTest86 V4 which is still available for download under 'Older Versions'. Phone, E-mail, Forum Support, plus free upgrades for 12 months after purchase.ġ. (French / German / Czech / Polish / Russian / Spanish / Portuguese / Italian / Catalan / Japanese / Chinese)
