Step 1: Download and install MemTest86 to your USB drive. To run this program, you need to install it onto a USB drive. MemTest86 is designed to run as a stand-alone, self-contained program from a bootable USB flash drive, CD-ROM, or floppy disk without an operating system present. However, MemTest86 supports Windows, Linux, and macOS, while MemTest86+ only supports Windows and Linux.

MemTest86+ is completely free and the latest version released in October 2022, has been rewritten for UEFI support and DDR4 and DDR5 RAM.

The free version lacks some features like DDR5/DDR4 DIMM Decoding, New 64-bit/SIMD tests, ECC error injection, SPD data validation, etc.

MemTest86 has a free and a pro version.

You need to download the older 4.3.7 version separately.

The latest MemTest86 version will not boot on non-UEFI systems.Which one should you use? I will prefer MemTest86+ and the reasons are as follows: They are developed by two different teams but started with the same code.īoth versions now support current multi-core processors and the corresponding chipsets. Memtest86+ is a development fork of the original MemTest86. Many people may be confused about the relationship between MemTest86 and MemTest86+. MemTest86+ is also a memory test program. Once it detects serious errors, you may need to replace the memory bar. MemTest86 is a memory test program designed to test and stress test an x86 architecture computer’s random-access memory (RAM) for errors, by writing test patterns to most memory addresses, reading back the data, and comparing for errors.
