What is memtest_vulkan?

memtest_vulkan is an open-source video memory stability testing tool built with Vulkan compute shaders. It was developed primarily to verify whether a graphics card’s (GPU) VRAM is operating correctly.

Unlike traditional CPU memory tests, it leverages the GPU’s parallel processing power to quickly scan large memory areas. It is particularly useful for confirming stability during overclocking, after repairs, or when checking used GPUs.

The tool is publicly available on its official GitHub repository (https://github.com/GpuZelenograd/memtest_vulkan) and runs on GPUs supporting Vulkan 1.1 or later. It supports Windows, Linux, and ARM64 environments with zero installation required.

Its key strengths are simplicity and immediacy. When an error is detected, it instantly displays the address range and bit error details, making problem identification straightforward. A minimum test duration of 6 minutes or more is recommended for reliable results.

Installation and Usage (Windows / Linux)

The biggest advantage of memtest_vulkan is that it requires no installation. Downloading the binary from the GitHub releases page is all you need.

On Windows

1. Go to https://github.com/GpuZelenograd/memtest_vulkan/releases and download the latest .exe file.
2. Save the downloaded file to any folder.
3. Double-click the file to launch it (no administrator privileges required).
4. The test starts automatically, showing progress in the console window.
5. Press Ctrl+C to stop the test at any time.

On Linux

1. Download and extract the appropriate Linux binary from the releases page.
2. Open a terminal and navigate to the extracted directory.
3. Run ./memtest_vulkan.
4. Stop with Ctrl+C as needed.

It also works on ARM64 systems, including Apple Silicon Macs and ARM-based Linux servers, provided the Vulkan driver is correctly installed.

Running the Test and Interpreting Results

Running the test is extremely simple. After launching, the tool automatically scans the entire VRAM and checks for errors.

During the test, real-time progress and any detected errors are displayed in the console. If no errors are found, it shows “PASS” upon completion.

Interpreting Results

• PASS (No Errors): The VRAM is stable and functioning normally. This is a good sign for overclocked setups or post-repair verification.
• Error Detected: Detailed information such as the exact address range, bit error locations, and patterns is shown. This helps pinpoint which part of the VRAM has issues.

Test duration varies depending on VRAM size and GPU performance, but running for at least 6 minutes is advised. Shorter tests may miss intermittent problems.

Supported Platforms Comparison Table

OS	Binary Format	Execution Method	Notes
Windows	.exe	Double-click	No admin rights required, Vulkan 1.1+ needed
Linux	Binary		Extract then run from terminal
ARM64	Compatible binary	Same	Apple Silicon / ARM Linux supported, Vulkan driver required

What to Do When VRAM Errors Are Detected

If errors appear, consider the following steps:

1. Retest: Run the test again under different conditions (e.g., change room temperature or update drivers) to check reproducibility.
2. Update Drivers: Install the latest graphics drivers from the GPU manufacturer’s official website.
3. Review Overclock Settings: Reset clock speeds and voltages to defaults and retest for stability.
4. Improve Cooling: Check case airflow and GPU temperatures, then improve cooling if necessary.
5. Hardware Inspection: Frequent errors may indicate physical VRAM failure. Contact manufacturer support if under warranty.

Errors do not always mean immediate failure, but ignoring them increases the risk of system crashes or data corruption. Prompt action is recommended.

Frequently Asked Questions (FAQ)

Q1: Is memtest_vulkan truly installation-free?

Yes. Just double-click the downloaded executable. No additional libraries or installers are required.

Q2: Which GPUs does it support?

Any GPU compatible with Vulkan 1.1 or later. It works with recent NVIDIA, AMD, and Intel models.

Q3: How long does the test take?

It depends on VRAM capacity and GPU speed, but at least 6 minutes is recommended. For 8GB+ VRAM, expect around 10 minutes.

Q4: Does an error mean my GPU is broken?

Not necessarily. Overclocking or driver issues can also cause errors. Retesting or adjusting settings often resolves them.

Q5: Can I use it on operating systems other than Linux?

Yes, it supports Windows and ARM64 environments as well, as long as the Vulkan driver is installed.

Q6: How do I save the test results?

Manually copy the console output or redirect it to a file (e.g., ./memtest_vulkan > output.txt). The tool does not have built-in auto-save.
