LATEST VERSION : 4.20 |

Based on the well-known original memtest86 written by Chris Brady, memtest86+ is a port by some members of the x86-secret team, now working at www.canardpc.com. Our goal is to provide an up-to-date and completly reliable version of this software tool aimed at memory failures detection.
Memtest86+ is, like the original, released under the terms of the Gnu Public License (GPL). No restrictions for use, private or commercial exist other than the ones mentioned in the Gnu Public License (GPL). Texts about the original version was taken from the original website and written by Chris Brady.

-= History =-
The first version of Memtest86+ was released on early 2004, based on memtest86 v3.0 that was not updated since mid-2002. Our main challenge was to provide an up-to-date version of this useful tool, as reliable than the original. Our work started when we got the first AMD64 system. Unfortunatly, the original memtest v3.0 didn't run at all. After looking at the source code, we fixed the bug.After some days, I saw lot of other things like chipsets or CPU that were not correctly detected or not detected at all. As I'm the chief-editor of a french hardware website (www.x86-secret.com now integrated into www.canardpc.com), I have access to lot of recent hardware and I can test and debug on quite all available motherboards on the market. After adding detection for all current CPUs, I've added detection for all current chipsets (SiS, VIA, nVidia, Intel) and ECC Polling for AMD64, i875P and E7205. Then, I decided to display some useful settings for the most popular chipsets. For exemple, on i865PE/i875P series, memtest86+ will now display FSB & Memory frequency, PAT status, memory timings, ECC status and the number of memory channels. Next version will perhaps contain several enhancements and bug-fixes.
