MemTest64
TechPowerUp Memtest64 is a free lightweight, standalone utility that lets you check your system memory for
problems at the hardware-level. It has a graphical interface, and can be run from within Windows.
Memory hardware errors can cause major application crashes, blue-screens of death (BSODs), and data
corruption. It is caused due to either faulty hardware, or bad memory timings/frequency. Memtest64 lets you
test your memory without having to pull out an MS-DOS boot disk. The utility loads your physical memory with
test-patterns, and can push other applications into the pagefile to free up memory for testing.
It can also be useful to overclockers who are looking to maximize memory performance by playing with timings
and DRAM speeds.
Features
- Runs on Windows XP, Vista, Windows 7, Windows 8, Windows 10, Windows 11. 64-bit OS only
- Supports all modern processors, including Intel Core and AMD Ryzen
- No reboot or DOS-mode required
- You can control how much memory to test, to reduce operational impact
- Memory is tested using various detection algorithms
- Errors will be detected automatically
