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).
