Memtest86+ – The Open-Source Memory Testing Tool

guest · Oct 24, 2022

Memtest86+ is a stand-alone memory tester for x86 and x86-64 architecture computers. It provides a more thorough memory check than that provided by BIOS memory tests. Memtest86+ can be loaded and run either directly by a PC BIOS (legacy or UEFI) or via an intermediate bootloader that supports the Linux 16-bit, 32-bit, 64-bit, or EFI handover boot protocol. It should work on any Pentium class or later 32-bit or 64-bit x86 CPU.

Memtest86+ v6 is a unified, free, open-source memory testing tool, released under GNU GPL v2.0.

Troubleshoot PC Instabilities
Memory errors are one of the most common causes of crashes, freezes and instabilities. If you encounter such issues with your computer, testing your RAM thoroughly is probably the first thing to do. Memtest86+ uses various algorithms to reliably detect failures. It will let you know if your RAM is faulty or not.
Ensure Initial Stability
Before using your brand-new PC, putting your new server into production, or after having overclocked your CPU or RAM, it's often wise to make sure there are no memory issues. Troubleshooting issues later can be annoying, costly, and time-consuming.

memtest86+ v6.0 Released As Rewritten Open-Source RAM Tester
by Michael Larabel @michaellarabel - October 25, 2022

Memtest86+ v6.0 has been released for this open-source system memory (RAM) testing utility. Memtest86+ v6.0 is the first major release of this program in nearly a decade and comes as a complete rewrite to better deal with modern hardware.

Memtest86+ 6.0 as part of the rewrite now features proper UEFI support, the ability to stress the latest AMD and Intel platforms with both DDR4 and DDR5 memory module support, support for up to 256 CPU cores, and many other enhancements over the prior nine year old release.

Memtest86+ 6.0 can be downloaded in the form of Linux ISOs or a Windows USB installer. Memtest86+ is available from memtest.org. At least back in the day this was a wonderful program for testing system memory if fearing faulty DDR DIMMs or other memory related stability concerns.
