MSI Afterburner is an overclocking tool for PCs which allows the users to customize their graphic cards to use the core voltage. Some of the users reported that it doesn’t have the GPU voltage control and so they can’t change core voltage in MSI Afterburner.
There could be unsupported desktop GPU models that require a temporary fix so as to have the Voltage Control and work on the MSI Afterburner. Below, we have provided guide how you can unlock the Voltage Control for a notebook GPU.
Steps how to unlock Voltage Control on MSI Afterburner
Using modified BIOS with the high bas voltage to allow the voltage control to use the remaining 100mV of excess voltage in MSI Afterburner. If you don’t want extreme overclocking, you should limit to +100mV. Here is the quick guide how to enable voltage control fix:
- Under the MSI Afterburner Profiles folder, navigate to VEN_10DE&DEV…, right-click on it and select Properties,
- Click on Security> Edits and then click Users,
- Check Allow permissions checkbox and then click on OK button,
- Click OK again to save the file,
- Now, open VEN_10DE&DEV… file in WordPad and replace what you see there with the below lines:
[Startup]
Format=2
CoreVoltageBoost=
PowerLimit=
ThermalLimit=
ThermalPrioritize=
CoreClkBoost=
MemClkBoost=
[Settings]
VDDC_Generic_Detection=1
- Go to the MSI Afterburner’s settings now and check Unlock Voltage Control and unlock the voltage monitoring option and then click Ok,
- Restart the app now and you will see that the GPPU voltage unlocks and can be used up to 100+mV.
Increase or decrease core voltage in MSI Afterburner
Increase the core voltage is more risks than benefits. It causes the increase in the heat output of the GPU and draws current. Also, it may permanently damage it if you exceed limits. There is a little chance of 5% for the MSI Afterburner when you try to force constant voltage. If you exceed, it might crashed at certain point.
You can tweak the changes of the core voltage of the MSI Afterburner using some benchmark app. It is easier to tweak the GPU settings if you run it on Windows mode. You can use the Settings to tweak such changes. Here are the steps:
- Modify the vBIOS voltage to 100mV below the suggested max Voltage for the GPU,
- You can flash the BIOS,
- Go to the check boxes under settings for the Voltage Control and Voltage monitoring the change the core voltage.
Remember that increasing the boast clock and voltage will lead the temperature load as you have switched from the default voltages and clocks. So, use the core voltage in a way that increased clocked speed, balance the power draw and reduce heat to operate in higher frequencies.
Conclusion
Now, we are round off the article. Hope so, you get the detailed guide on what to do if you are dealing with can’t change core voltage in msi afterburner. We wish the steps are helpful for you. However, if it does not, you should look for PC related issues and get their automatic repair using the recommended tool whose direct download link is provided below.
