MemTest is a RAM tester that runs under Windows. It
verifies that your computer can reliably store and retrieve data from memory. A correctly functioning
computer should be able to do this with 100% accuracy day in and day
out. A computer that fails these tests, perhaps because of old hardware, damaged
hardware, or poorly configured hardware, will be less stable and crash more
often. Even worse, it will become even less stable over time as corrupted data
is written to your hard disk.
By running MemTest you can ensure that your computer's RAM correctly functions. It is wise to test this when you buy a new
computer, install new RAM, or change the configuration of your machine (for
instance, to overclock it). Are you the sort of user who likes to push
the performance of your machine to the edge? Relying upon whether your machine
will boot after your new BIOS tweaks is a poor way to determine the safety of
your new settings. Use Mem Test as a true test of stability.
6.0: optimized for computers with >4GB ram. Particularly
significant for Deluxe users. If you are testing 8GB or more you need
this version. If testing less than 4GB, 5.x may actually be slightly
faster. Based on extensive empirical research we have updated the
percent coverage metric; testing to 100% will catch all errors except
for intermittent failures; to detect intermittent problems test to 400%.
5.1: /nice switch, and test starts faster
5.0: 30% faster than 4.x!
