Is your graphics card memory free of errors? Test the GPU memory quickly and thoroughly! Works on nVidia discrete GPUs.

Download GpuMemTest v1.2 (for Microsoft Windows Vista / 7 / 8 / 10 )


  • It's free!
  • Simple to install and use.
  • Fast! Detects most errors in seconds.
  • Reads and writes at full memory bandwidth. Testing time is reduced by a factor of 10.
  • Multiple test patterns: sequential, random, alternating R/W, block copy, random data and sparse inversions.
  • Stresses GPU memory and GPU memory controller.

GpuMemTest is suitable for anyone who wants to verify that their hardware is not faulty.

GpuMemTest is suitable for overclockers (only on nVidia GPUs!) who want to quickly determine the highest stable memory frequency. We recommend setting the memory frequency to be no higher than 90% of the highest stable frequency. Please do not use GpuMemTest for overclocking on AMD GPUs, as it might fail to detect errors.

GpuMemTest is suitable for CUDA and OpenCL programmers, because having confidence in hardware is necessary for serious application development.
