Disable automatic downclocking?

post #1 of 3
Thread Starter 
I'm unable to disable the hardware automatic downclocking and undervolting while idling in a 3D application with my 570. If I open 3DMark11 for example and take some time picking my settings, both the voltages and clock speeds drop to regulate power usage when not necessary (takes ~10 seconds before it converts to 2D power state). This also happens in between the Graphics Tests in 3DMark11 and similarly for during any loading screen in a video game. It is a cause of instability with an otherwise completely fine OC.

I've forced max performance through Windows, Nvidia Control Panel (I changed from "Adaptive" to "Prefer Max performance") and MSI Afterburner ("Force voltage"), then rebooted, and it STILL keeps downclocking. In Afterburner I also tried setting both the 2D and 3D profiles to my max OC, along with forcing the voltage in the first tab. No dice...

If I'm playing a game I want the voltage at the OC setting 100% of the time, regardless of whether I'm in a lobby, loading screen, or whatever. Otherwise it can downclock and power save all it wants. If I can't do this then I have to drop my OC a bit which is kind of sad face.

Does anyone know how to force this? Nothing seems to work.

this probably isnt the best way but you can leave gpuz running and it will force your card to its 3D clocks and voltages. some of the very old versions dont work though and some newer versions dont either. i can confirm 0.4.6 does work however.

Hmm yeah because that wasn't working for me. In fact I was using GPU-Z to monitor my voltages. I'll look around for 0.4.6 to see if that works.
