![]() ![]() Improved USB keyboard support, including systems that fail to emulate IO Port 64/60 correctly (eg.Graphical interface with mouse input where supported by the underlying UEFI system.Option to disable CPU caching for all or individual tests.Improved multi-threading support, where supported by the underlying UEFI system.No longer requires the use of the PAE workaround to access more than 4GB of memory.This is the result more moving to native 64bit code, removing the PAE paging hack, switching compilers and using faster random number generation algorithms. Speed improvements of between 10% and 30%+.Addition of 2 new memory tests to take advantage of 64bit data and SIMD instructions. ![]() When booting from UEFI, MemTest86 has access to additional services not available in BIOS including: MemTest86 supports booting from the newer UEFI platform. Other features include support for DDR3, DDR4, UEFI, XMP, 64bit, secure boot and ECC RAM.What's New in MemTest86 for the UEFI platform (Version 5 and later)? Once booted, MemTest86 runs through thirteen different tests as well as reporting on the specifications of the RAM installed in the machine.Tests can take between 30min to several hours to run, depending on your hardware and the amount of RAM installed. Often you need to change the boot order in BIOS to select the flash drive as the boot drive. This wipes the existing content of the flash drive, but makes the drive bootable. To use the software you need to copy the files to a flash drive. MemTest86 can help diagnose faulty RAM (or rule it out as a cause of system instability) Bad RAM is one of the most frustrating computer problems to have as symptoms are often random and hard to pin down. Corrupted data, crashes and unexplained behavior. Unreliable RAM can cause a multitude of problems. 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. MemTest86 is the original, free, stand alone memory testing software for x86 computers. ![]()
