Why am I getting constant GPU voltage even though it's unchecked on Afterburner?

post #1 of 19
Thread Starter 
Hi there, I have selected a 1025mV voltage value via MSI Afterburner, however I didn't check the "Force constant voltage" box. I assumed that MSI Afterburner would reduce the voltage when the card is idle and bump it to 1025mV when stressed, but that is not the case.

The card is on constant 1025mV even when idle on windows. Doesn't that kinda beat the point of having a force voltage box? Is this normal?

MSI AB does reduce the voltage on my cards when the Force Constant is unchecked.. Maybe something is making your card run 3D clocks all the time?

eh..once you use an overclocking tool..it stays @ the overclocked voltage..if you want it to throttle down..only apply the OC when you're ready to use it..disable afterburner starting up with windows n stuff..

So what does the "force constant voltage" on Afterburner do? I had the impression that the program would throttle down when idle.

it depends on what voltage regulators your card has. but technically msi afterburner only officially supports msi cards. since you are using another brand, theres no guarantee any of the functions will work 100%

If the card runs 24/7 at 3D clocks and voltage, could it be a problem if it runs all the time at 1100mV and overclocked?

Make sure the option is disabled, then exit afterburner, and launch it again.

It seems bugged with voltage and fan control, ie, it keeps both voltage and fan speed constant for some reason. It has lead to overheating for me in the past.

Never had either of those issues with none of my cards. Everything works, guys, just not for you smile.gif

The card sits on around 42c on idle and around 55-60c when gaming. I assume the temperatures are fine, but I am worried about the constant voltage and clock speed. Aren't thouse diminishing the card's life cycle if they are forced 24/7?
