Quick Overview: What MSI Afterburner Can Do

How to Download and Install MSI Afterburner

Step 1: Download from Official Source

MSI Afterburner should only be downloaded from msi.com or guru3d.com to avoid phishing websites that may modify the program or disguise themselves to steal your data . The current version for 2026 is fully compatible with Windows 10 and 11, with support for NVIDIA RTX 50-series and AMD RX 90-series cards .

Step 2: Run the Installer

Double-click the downloaded file. When the installer runs, it will ask you to select a language—choose your preference and click OK.

Step 3: Install RivaTuner Statistics Server (RTSS)

During installation, you’ll be prompted to install RivaTuner Statistics Server (RTSS) . This is critical—RTSS is what powers the on-screen display that shows FPS and temperatures in your games . Make sure to check the box to install this component.

Step 4: Complete Installation

Follow the installer prompts. A second installer window will appear for RTSS—click OK to continue . Once finished, launch MSI Afterburner. You’ll see a dashboard showing GPU temperature, core clock, memory clock, and fan speed .

Setting Up the On-Screen Display (OSD)

This is what most gamers want—real FPS and temperature numbers visible while gaming.

Step 1: Open Settings

Click the gear icon in the MSI Afterburner main window to open settings .

Step 2: Navigate to Monitoring Tab

Here you’ll see a long list of hardware stats you can display: GPU temperature, GPU usage, core clock, memory clock, fan speed, CPU temperature, CPU usage, RAM usage, and framerate .

Step 3: Select What to Show

For each item you want to see while gaming:

• Click the item to highlight it

• Check “Show in On-Screen Display” at the bottom 

Recommended stats to enable:

• Framerate (most important)

• GPU temperature (monitor for overheating)

• GPU usage (see if you’re GPU-limited)

• CPU temperature (if you have cooling concerns)

• Frametime (shows stuttering as a graph) 

Step 4: Customize Display Appearance

Go to the On-Screen Display tab. Here you can:

• Set a hotkey to toggle OSD on/off

• Change text color, position, and font size

• Adjust background transparency 

Step 5: Save and Test

Click OK, then launch any game. You should see the OSD appear. Use your hotkey to toggle it off if it’s distracting during cinematics.

Note: Both MSI Afterburner and RivaTuner Statistics Server must be running in the background for the OSD to work .

One-Click Overclocking with OC Scanner

MSI Afterburner includes an automated overclocking feature that tests your GPU and finds stable settings automatically . This is the safest way for beginners to overclock.

Before You Start:

• Save all your work and close other applications—the process takes about 20-30 minutes 

• Ensure your GPU has adequate cooling

Step-by-Step OC Scanner:

1. Open Settings and go to the General tab

2. Enable “Unlock voltage control” and “Unlock voltage monitoring” 

3. Click Apply, then OK

4. In the main window, slide the Power Limit and Temperature Limit sliders to the maximum (right side) 

5. Click the magnifying glass icon with “OC” on the main window, or go to Settings and select Curve Editor 

6. Click “Scan” to start the automated overclock

7. Wait 20-30 minutes for the scan to complete

8. Once finished, the core frequency curve will display in the editor

9. Click the save icon (floppy disk) to save your new profile to one of the 5 profile slots 

10. Click Apply to enable the overclock

Test Stability:
Run a stress test with Unigine Heaven or FurMark for 10 minutes. Watch for:

• Visual artifacts (weird colors or shapes)

• Crashes or freezes

• Driver timeouts

If any issues occur, the overclock may be unstable. Consider reducing the curve slightly or testing a different profile .

Manual Overclocking (For Advanced Users)

If you want more control than OC Scanner offers, here’s how to manually overclock.

Step 1: Increase Core Clock

Start with +25 MHz increments. Click Apply. Run a quick game or benchmark for 5-10 minutes. If stable, add another +25 MHz. Repeat until you see artifacts or crashing, then dial back 10-20 MHz .

Step 2: Increase Memory Clock

Once core clock is stable, repeat the process with memory clock. Start with +50 MHz increments. Memory overclocks are often more forgiving but less impactful for gaming performance.

Step 3: Adjust Power and Temperature Limits

Max these out—most modern GPUs have built-in protection. This allows the card to draw more power when needed for your overclock .

Step 4: Save Your Profile

Once stable, click the save icon and select a profile number (1-5). Your overclock will load automatically when you open Afterburner. You can also enable “Start with Windows” to have your overclock applied on every boot .

Undervolting: Lower Temperatures Without Losing Performance

Undervolting reduces GPU voltage while maintaining the same clock speeds—lower temps, less fan noise, and often the same or better performance.

How to Undervolt:

1. Open the Curve Editor (magnifying glass with OC icon)

2. The graph shows voltage (X-axis) vs frequency (Y-axis)

3. Find the voltage point where your GPU normally runs under load (e.g., 1000mV)

4. Select that point and the points to the right

5. Drag them down to match the frequency at a lower voltage

6. Click Apply and test with a benchmark

For laptops, MSI Afterburner works with mobile GPUs, but use smaller boosts and monitor CPU and GPU temperatures closely .

Custom Fan Curve: Keep Your GPU Cool and Quiet

Default fan curves prioritize silence over cooling. A custom fan curve ensures your GPU stays cool without sounding like a jet engine.

Step 1: Open Fan Settings
Click the gear icon, then the Fan tab. Enable “Enable user-defined software automatic fan control” .

Step 2: Set Curve Points
A good starting curve:

• 30°C: 30% fan speed

• 50°C: 40% fan speed

• 65°C: 60% fan speed

• 75°C: 75% fan speed

• 85°C: 100% fan speed

Step 3: Apply and Test
Save and run a demanding game. Monitor temperatures with the OSD. Adjust the curve if you prefer quieter operation or more aggressive cooling.

Note: Laptop GPUs cannot use custom fan curves—they are preset by the manufacturer in the BIOS .

NEW in 2026: GPU Protection Features

MSI Afterburner 4.6.7 Beta 2 introduced critical GPU protection features, especially for RTX 50-series cards with 16-pin power connectors .
