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.
