Why am I getting constant GPU voltage even though it's unchecked on Afterburner? - Page 2

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?

It turned out that the fix was in the NVIDIA Control Panel. In the 3D Settings under "Power Management Mode" I had "Prefer Maximum Performance" selected. When I switched it to "Adaptive", my OC finally downclocked as did the overvoltage. I would also recommend that you have the Windows power management policy at least set to "Balanced" to ensure that your video card will ease up when idle.

Thank you for your answer, there is one thing I need to know however. Is it safe to have the card overclocked 24/7 or is it recommended to use the energy saving feature? Does either of those settings affect performance?

It doesn't affect performance, and it's better to have power saving on. Reduces heat, reduces voltage, makes the chip live longer.

http://downloads.guru3d.com/NVIDIA-Inspector-1.94-download-2612.html

Download nvidia inspector, your BIOS has 3 performance presets with different clock speeds / voltages for each preset. Generally it has 2 "downthrottled" presets and 1 performance preset.
Run nvidia inspect, click the overclocking tab on the bottom - are your BIOS presets, actually set to downthrottle?

Now if your BIOS is messed up, you can try to fix it in nvidia inspector OR you can switch to your other BIOS on your card.


After checking, this - also make sure your power management in nvidia control panel is set to "adaptive" and not "prefer maximum performance." Further, go into power management in your windows control panel, i'm not sure if that interacts with anything but it can't hurt to try. Once you've changed your settings, reboot - when you're back at your desktop minimze everything for 2-3 minutes and then open up AB to check your clockspeed/voltage.

Any luck with this? And yes, you absolutely want your card to downthrottle smile.gif No reason to be fully clocked when browsing the web.

Well, it is "safe" to do that, in that your card won't explode while it's sitting there doing nothing some day. At the same time, it's recommended that you use the energy saving feature for reasons already listed.

Neither will affect performance; you might come across a situation where you might be playing an older game for example, and it won't run well because it can't get your card out of the downclock. To fix this, you would go the the 3D settings in the NVIDIA Control Panel, then hit the Program Settings tab, find the .exe file of that game, and adjust the power management from there. Doing that will make your card go at max performance when playing that game, while at the same time retaining the adaptive setting when you're not playing it.

do u have multiple monitors or the max performance mode selected in the nvidia control panel?

I am using one monitor and it's on Adaptive. Also the power settings on Windows 7 are on balanced. However I have the Apply overclocking at startup enabled (on MSI afterburner). Shall I disable it?

No, you shouldn't. Did you check your BIOS presets? There are 3 preset voltage / clock speed settings in your BIOS depending on how heavily your GPU is being used. Referenced in my post above

So I'm guessing you're still experiencing issues? If so, I'd look to xoleras and what he has stated.
