![]() They are diverging slightly now but once you get either version running they should both provide a solid RAM test. Nonetheless the core test algorithms in both versions were common for a long while and can be traced back 40 years. So it won't work on most machines without a deep dive into the BIOS settings. The lack of secure boot being especially problematic for novice users as Win11 requires secure boot to be on, but Memtest86+ requires it to be off. So for example, it now has DDR5 support, but is still missing a lot of important stuff like ECC support, Secure boot support, row hammer testing and the ability to log a test report to disk. This release today brings it forward a few years. So the plus version was around 9 years behind. PassMark added ECC support, Secure boot support (with Microsoft code signing it), Mouse support, a graphical UI, logging of test reports to the disk, Native 64bit, Some 128bit testing, support for a heap of new CPUs, DDR5 support, row hammer testing, command line boot configuration, PXE network booting, multi-language support, inventory checking, ECC injection, debug logging, performance improvements, ARM CPU support, memory address decoding (to tell you exactly which memory stick and chip on the stick is bad) and a bunch of other stuff.ĭevelopment on the MemTest86+ version was discontinued as there have been minimal updates since 2013 (until today that is, with this new V6 release). PassMark did five major releases between 2013 and today. However, from V5 with the the software is being released under a proprietary license. The MemTest86 v4 project (for traditional BIOS) is still maintained and remains GPL open source, for use on old machines. The core software still remains free to use without restrictions. Starting from MemTest86 v5, the code was re-written to support self-booting from the newer UEFI platform. The 64bit era was here, DDR4 was coming, UEFI had already arrived and Microsoft's Secure boot technology threatened to prevent MemTest86 from booting on future PC hardware. This was around the time that a lot of technological changes were occurring. In Feb 2013, after another long period of not much development, PassMark Software took over the maintenance of the original MemTest86 project from Chris. Added Motherboard Manufacturer & Model reporting. Added experimental SMT support up to 32 cores (Press F2 to enable at startup) Added complete detection for memory controllers. MemTest86 (the original) and the plus version exchanged a bunch of source code in this period. Added support for up to 2 TB of RAM on X64 CPUs. The original MemTest86 was continued to be developed across 2004 to 2013, with multiple updates made - most notably the stable Version 4.0 release. Nevertheless, both Memtest86s subsequently continued to be developed. ![]() MemTest86 boots from a USB flash drive and tests the RAM in your computer for faults using a series of comprehensive algorithms and test patterns. The naming was unfortunate as it now leads to total confusion between users. Free Download PassMark MemTest86 Pro for Windows is the original, free, stand-alone memory testing software for x86 computers. MemTest86 was released as free open source (GPL) software during this period.īetween 2002 – 2004 (during the time period of the MemTest86 V3.0 release and there wasn't much activity from Chris) the code was 'forked' by Samuel Demeulemeester (formally part of the French CanardPC publishing group in France) into another version of the software called MemTest86+. Between 19, support for 64bit was added (but only via PAE paging), new CPU types, symmetrical multiprocessors and many other features have been added during this period. ![]() Since then, there have been more than a dozen new versions released. However, some of the testing algorithms used have been under development since 1981 and were previously implemented on Dec PDP-11, VAX-11/780 and Cray XMP (an old super computer) architectures. Memtest86 Free Edition has not been rated by our users yet.MemTest86 (without the plus) was originally developed by Chris Brady (BradyTech Inc) with a first release in 1994. Memtest86 Free Edition runs on the following operating systems: Windows. The most prevalent version is 9.0, which is used by 100 % of all installations. It was initially added to our database on. The latest version of Memtest86 Free Edition is, released on. It was checked for updates 31 times by the users of our client application UpdateStar during the last month. Memtest86 Free Edition is a Shareware software in the category Miscellaneous developed by PassMark Software. Therefore, if the computer does not work properly, hangs, there are various types of "rubbish" on the screen, we should first use this program. Memory (especially the lower class) is next to the operating system itself the most common element that can affect the unstable operation of the computer. Download Memtest86 10. A very good program for testing RAM memory bones in your computer.
