Can't change core voltage in MSI Afterburner: 3 ways to fix it

After installing MSI Afterburner, you may notice that it does not have GPU voltage control.

Some unsupported desktop GPU models require a temporary fix for voltage control and work in MSI Afterburner.

Find below a method to unlock the MSI Afterburner lock voltage for your laptop GPU.

How to unlock the voltage control of MSI Afterburner?

Unlocked Voltage control on MSI Afterburner is limited to 100 modified boost allowed values.

Try using a modified bios with a high base voltage to allow voltage control to use the remaining 100mV overvoltage in MSI Afterburner, making it a primary OC utility. If you don't want to do extreme overclocking, you should limit it to 100mV.

Let's see how to enable voltage control fix:

1. First, go to the MSI Afterburner Profiles folder.
2. Right click on the named fileVEN_10DE&DEV…
3. Select Properties.
   
4. Click Safety.
5. Select Edit and click User.
6. Check the Allow permission box.
7. After editing, click "OK" and "OK" again to save the file.
8. You can now open the file named VEN_10DE&DEV... in WordPad and replace what you see with Startup]Format=2CoreVoltageBoost=PowerLimit =ThermalLimit=ThermalPrioritize=CoreClkBoost=MemClkBoost=[Settings]VDDC_Generic_Detection=1
9. Enter MSI Afterburner settings, check "Unlock voltage control" and Unlock voltage monitoring, click OK.
10. After that, you can restart the application.
    

#GPU voltage control unlocked, can use up to 100mV, including GPU voltage in OSD.

Can I increase the core voltage of the MSI afterburner?

Increasing core voltage brings more risks than benefits. It increases the heat output of the GPU and consumes current. Additionally, if you exceed the limit, you may permanently damage it.

There is a small 5% chance of MSI afterburner when trying to force constant voltage. This is because MSI has an automatic overclocking feature to regulate core voltage. So it either works or breaks down at some point.

How do I lower my core voltage in MSI Afterburner?

If you can't adjust the core voltage, you can use MSI afterburner with a baseline. Download and install Heaven Benchmark and remember to deselect the full screen option from the settings menu. When running in Windows mode, it is easier to adjust GPU settings simultaneously.

How to change the core voltage of MSI Afterburner?

1. Modify the vBIOS base voltage to 100mV below the recommended GPU maximum voltage.
2. You can flash the bios; some GPUs need to be refreshed to unlock.
3. Go to the checkboxes in the "Voltage Control" and "Voltage Monitoring" settings to change the core voltage.

You should also note that increasing the boost clock and voltage will result in higher load temperatures since you have switched from the default voltage and clock.

How to use core voltage?

You can use your device's core voltage to increase clock speeds, balance power consumption, and reduce heat to run at higher frequencies.
