This freeware accurately checks the memory of x86 computers, but Memtest86's floppy-boot-disk installation lessens its mass appeal.
This utility won't install to your hard drive; it can only install on a bootable floppy disk. There is no interface, as it immediately checks your computer's memory. Memtest86 is quick and accurate. However, system administrators looking for a memory tester will probably pass on Memtest86, as many current machines don't include floppy drives.
Home users with older PCs will appreciate the simplicity of Memtest86. It can't get any easier than inserting a disk and rebooting your PC. We can easily recommend this freeware for home users who have floppy drives and a need to check their computer's memory.
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.
Unreliable RAM can cause a multitude of problems. Corrupted data, crashes and unexplained behavior. Bad RAM is one of the most frustrating computer problems to have as symptoms are often random and hard to pin down. MemTest86 can help diagnose faulty RAM (or rule it out as a cause of system instability)
MemTest86 does NOT run in Windows. To use the software you need to copy the files to a flash drive. This wipes the existing content of the flash drive, but makes the drive bootable. Often you need to change the boot order in BIOS to select the flash drive as the boot drive.
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.
Other features include support for DDR3, DDR4, UEFI, XMP, 64bit, secure boot and ECC RAM.
Excellent utility for testing for RAM errors. The test suite is very thorough and will catch all sorts of issues that can arise when physical RAM shows anomalies.
None that I have encountered.
Don't let the low ratings fool you. Those that gave 1 star reviews are simply not technical enough to use the software correctly. Burn it to an optical disc or build a bootable USB drive to use Memtest86. As the Editor's review states, do not simply decompress and run in Windows (or OSX or *nix).
Does a deep test on your RAM sticks. Version 6.0 supports the newer memory technologies. Such as DDR4, 64bit and the UEFI graphical BIOS's found on new PCs. You can now also get a test report written out to your USB drive at the end of testing. Software is free.
This isn't software that runs in Windows like some of the old reviewers seemed to think. It boots from a USB drive (or a CD) that you need to prepare following the instructions in the download.
It can also be slow to run, it can take an hour or more. I run it overnight.
Support for traditional BIOS and floppy disk has been dropped in the latest release. but does anyone use a floppy disk anymore?
