Memtest86 is a comprehensive, stand-alone memory diagnostic. Memtest86+ is software designed to stress test an x86-compatible computer's random access memory (RAM) for errors. It tries to verify that the RAM will accept and correctly retain arbitrary patterns of data written to it.
Memtest86+ is designed to run from a bootable floppy disk, CD-ROM, USB Drive, or from a suitable bootloader without an operating system present. Memtest86+'s tests are comprehensive so it can find otherwise hidden problems on machines that appear to work normally. With many chipsets, Memtest86+ allows counting of failures even in error-correcting ECC DRAM.


Memtest86 was originally developed by Chris Brady; Memtest86+ is developed by Samuel Demeulemeester. The first version of Memtest86+ was released on early 2004, based on memtest86 v3.0 that was not updated since mid-2002.

Memtest86+ writes a series of test patterns to every memory address, reads back the data written, and compares it for errors. Information about the chipset can be used to enhance these tests — particularly in an overclocked system. Many chipsets can report RAM speeds and timings, and some even support changing the memory timings on the fly; in this way, Memtest86+ can test that memory remains error-free with the more aggressive settings.

Thanks for sharing

anybody try it ?? feedback ?

how to use it?i already dlod it..dunnow how to start...

install to the floopy disk and boot it. Correct me if wrong

thanks for sharing bro.

Actually can we run the Memtest86 under window instead of in the boot screen? What I means is, got a version to run under window?

Dun think that you can run it under Window...

memtest has a version that can run in windows
