Help me with adjusting the voltage settings for the Radeon VII.
Help me with adjusting the voltage settings for the Radeon VII.
You want to lower the voltage on your Radeon VII for better stability and lower power usage, but you're not sure which settings to adjust in Wattman. It can help to increase stability and cut power without making the fan too loud. Please let me know if you need further guidance.
Do you believe that since the voltage is set to normal, it will fail?
If you reduce the voltage, will it no longer cause a crash?
[H]ardOCP: AMD Radeon VII Chilling & Undervolting
Looking to boost power efficiency, lower GPU temperature, and reduce fan noise while keeping gameplay smooth. Could Radeon Chill or GPU undervolting be the solution? We test the Radeon VII in real-world games and demonstrate the effects clearly...
lowering the voltage won't improve stability; it will actually harm it. to boost stability, you should raise the voltage, lower the clock speed, and increase fan speeds. though it's possible there might be an issue with the game, if not, consider getting a replacement card from the manufacturer.
Is the crashing coming from another place than your system RAM? Reducing the voltage will help maintain FREQUENCY stability. That means the clock speed would stay higher rather than slowing down. For GAME stability (avoiding crashes), lower voltages could actually hurt performance. If your settings are set to auto, that’s usually the most stable but also the most power-consuming option. Here’s a guide on undervolting: I’ve adjusted settings for AMD Polaris cards. You can’t directly reuse the voltage-frequency chart, but it shows what WattMan displays. Similar to tweaking the CPU, you’ll need to check stability with your chosen changes.
